Title: Hobbs NX-Studio Build
Post by: Hobbsmeerkat on 23 Aug 2020, 10:45 pm
I don't yet have the actual driver kit, but since I have the flatpack, I might as well get started with the assembly now that I have some proper tools and my raw-wood veneer/stain etc.

Here are my pics from the flatpack thread:

Raw quilted-maple veneer: (2 matching sheets)

I only have enough clamps for one speaker at a time, so following Peter's video, its time to start assembly with the slope:

I should be able to get everything for this speaker all glued and clamped up tonight! So expect some more pics as I go along!

That quilted maple is going to look gorgeous.
I certainly hope so! Still not 100% sure how i want to do it, but the first thing i need to do is flatten it. Its a really wavy veneer. Ill probably run up to the store and get a couple 2'x4' sheets of plywood and some shop towels to then clamp down with the wood plasticizer i got along with the veneer.  :thumb:

I already have a small test strip being flattened out on the porch that I'll then use to dye it a deep "mahogany red" and figure out what allows for the best application. Luckily it can also be added to laquer if staining doesn't achieve the desired results. Tho i will say, finding denatured alcohol was a total pain. But with the massive amounts of sanitizer being produced, im also not too surprised.

I was only able to get 6 clamps, and both HD & Lowe's were running really low on them, and most that remained were 6" or 36" or $30-40 a piece... lol  :o
So I got 4x 24" clamps and 2 strap clamps instead and they seem to work really well thankfully!

Here's a rough dry fitting with the clamps!

(https://www.audiocircle.com/image.php?id=213629&size=large)

The clamp on the bottom will get put on the front instead once i start clamping them down after glueing..
Title: Re: Hobbs NX-Studio Build
Post by: Hobbsmeerkat on 24 Aug 2020, 12:22 am
Glue up done! The dry fit definitely made planning a little easier, by putting the strap clamps under the side panel first then adding all the other sides/braces/shelf using the straps first to keep it all in place, putting one clamp running front to back, then adding the other  24" clamps to the top/bottom, moving the one that was front-back last.

(https://www.audiocircle.com/image.php?id=213631&size=large)

Now I just gotta let it dry!
Tomorrow, I'll flush trim the back and start on the 2nd one.

I agree with Alex, that veneer  will be killer  when you're all done.

Not sure if you've seen this but here is a pair of Encore's I did  some time ago for my nephew... he and his  girlfriend wanted red so....

I used   some  water based red  dye I picked up from Lee Valley, they do have  a  few differentshades, you'd have to go look at  a color chart but it worked well.  The more you  put on, the darker it will get,  don't  get it on  your cloths or the  shop floor.....    trust  me

Hobbs, looking at that I'm betting you're using stain of some type. If you want it to look like the guitar you've pictured elsewhere, dye and tone coats are in your future. Stain will surely obscure that lovely grain. Dye doesn't do that but has other sometimes weird characteristics.

 Conceptually you can think of it as if you're looking through a red colored lens at the wood.

If you're willing to take time and effort to get there, I can help, but it's not what I'd call a quick and dirty process.

Count me as one person that would be very interested in any knowledge you share in this area! I did find that the depth of the grain on my ribbon mahogany veneer came out nice but not as three dimensional as I was hoping. Perhaps it was the use of stain before the poly.

I am sertainly using a dye,

But by all means! The stain im using says i can use it in the wood, or mixed into laquer, so maybe be latter option is my best bet? Any info you can share will be greatly appreciated!

If you want the curl to pop a little bit you can always dye your veneer black sand it off and then use your red dye. By sanding the black is left in the curl.  Here is a pic of some Infinity RS-3000 speakers I worked because I was getting bored this last srping.

What is the product you're using? Are you planning on spraying lacquer?
Title: Re: Hobbs NX-Studio Build
Post by: Hobbsmeerkat on 24 Aug 2020, 07:59 pm
What is the product you're using? Are you planning on spraying lacquer?

Its a product from VeneerSupplies called Transtint. I don't have a sprayer or booth, but I do know some guys that paint/restore cars that may be able have them do for me or let me borrow their booth
Title: Re: Hobbs NX-Studio Build
Post by: Peter J on 24 Aug 2020, 09:23 pm
Transtint is a good and versatile product. Jeff Jewitt of Homestead Finishing developed it. If you're going for the bright red like guitar you've shown, I think Perfect Red or Bright Red would be a place to start. I'm guessing what you've got is Bordeaux or something else.

If your friends are willing to work with you or loan you a gun the process in essence is:

1. Get surface flat and sanded to 180 or perhaps 220
2. Dye to desired color and intensity. Sneak up on it, get to saturated in color and it's hard to unwind.
3. Tint next few topcoats, clear the last.

 I've also dissolved Transtint in lacquer thinner and  feather sprayed in between topcoats. You can do bursts or darken edges and lots of other effects by concentrating  in specific areas or even over stencils or frisket paper. 
The nice thing about using dye to tone coat is it doesn't cloud grain so you don't obscure all that's going on in that grain. The lens analogy is a good thing to keep in mind. Pigment in lacquer is more opaque.

Jeff's got some good info on his site and I think a forum, although I don't visit often. I have several of his books, but I suspect the web and YouTube have all but replaced them.

Post by: Hobbsmeerkat on 24 Aug 2020, 09:41 pm
Yeah i started with "Mahogany Red" cuz the site made it appear like a darker red, but it definitely looks more like Bordeaux, which i imagine leans further purple. But the brighter red is definitely the look im going for, with a black front, tho i may just veneer the whole front and sides & paint only the waveguide/bottom/grill/shelf. I've got a fair amount of veneer to work with thankfully. Matched pair of sheets.

I ended up going with "Perfect Red" this time, which will be here in a couple days. But I definitely plan on having this project be a slow & steady one, read up on that site to figure out how to best proceed.l in the meantime

Should i be sticking with lacquer, dye and lacquer thinner to make it thin enough for a spray gun, & when you say "dye to desired color" do you mean the dye the wood or the lacquer? Im guessing the lacquer and spray on test strips to get desired results?

Concentration in carrier (alcohol) will control intensity. Lacquer shouldn't have to be thinned for spraying, but you may want to for the tone coats. Transtints can be mixed and matched.  I'd get your base color with dye alone, then build depth and shift color slightly with topcoats.  Alcohol evaporates quickly so while you can't thin lacquer with it, it can be used in between lacquer topcoats as long at it's allowed to dry.

I like lacquer and almost all nasty solvent finishes for their versatility, quick drying, and sometimes toughness (conversion varnish), but I'm old school in that regard. Choose a workable path and stay on it. The wheel has been invented already. You need a good respirator and ventilation with all of it.

So if I'm reading you correctly, add the dye to the lacquer for the desired intensity, and blend in more lacquer with each coat, to reduce intensity with each coat, and none for the last coat?

Or are you saying to spray clear lacquer, spray the dye at full strength, and lessen the concentration with alcohol between each layer of lacquer?
Title: Re: Hobbs NX-Studio Build
Post by: AlexH on 24 Aug 2020, 11:01 pm
I think what Peter is saying is to dye your veneer if not as deep red as you would like then add some transtint to you finish and use it as a toner. When adding transtint to the finish it is more translucent color (ie not as colorful)  and you can keep adding coats until the desired color is achieved. This allows you to sneak upon the color you were looking for. And IMHO gives you a color with more depth. Finishing is everything. It can make or break your project.

Dye at full strength to me is undiluted, don't do that!

Alex says it better than me, it's a lot for me to convey in a few sentences. It just gets too in depth and most folks would like pat answers, which is why I hesitate to bring it up on this forum.

 There isn't a specific formula, it's a work-up-to-it methodology that lets you decide with each coat. Not like paint. One cool thing about lacquer is film thickness isn't critical and it dries fast so you get previews along the way.

Your painter friends will relate to this: It's kinda akin to candy finishes on cars. Base color, then translucent color, then clear top coat(s).

LMAO okay I think so get it now. lol
Stain the veneer & add tone coats as needed. Got it!  :thumb:
I'm all about learning, tho I'm definitely a person that learns better by watching & doing better than just reading. lol so probably a good idea to run off to youtube then!
I can't blame ya for not wanting to delve too deep into it tho, all of these projects take time. Once the new dye arrives ill take some new strips of the veneer and brush on some thin coats of dyed veneer to see what sort of effect I can achieve. Before I move to the actual towers.

Candy finishes are a good way to explain it.

Thanks, Peter!

Hobbs- That quilted maple is going to be stunning!  I am super excited to see this build :D

Quilted maple has always been one of my favorite woods visually, as are birdseye, curly and flamed.
So working with some for this build is gunna be interesting!

Not 100% sure yet, but probably paint on the front/bottom and veneer on the back/sides/top. But i may veneer the majority of the cabinet except the waveguide, shelf and bottom. Not 100% sure tho.. but if i wanna do a more guitar style veneering, itll need to be a split veneer along the center of the face, but i dont think im skilled enough for that yet.. :p
Title: Re: Hobbs NX-Studio Build
Post by: Hobbsmeerkat on 30 Aug 2020, 11:09 pm
Got the "perfect red" dye in this time.

I also did a little bit of "tone coating" with a small brush to get a better understanding of how this is supposed to look in a more "finished" appearance.

(https://www.audiocircle.com/image.php?id=213841&size=large)

Left: dye & toned lacquer
Right: dye only

While it is definitely more "red" than the "Mahogany Red" it's still not quite the tone I'm looking for, so I've already ordered a bottle of "bright red" which will go thru the same process as above.

I want to do a few different tests as well, where 3 strips will be dyed and toned with the same base color, then strips that are dyed one color but toned with different colors to find which option I think will look best.

So look forward to that in the near future!  :thumb:

Okay! I got the "Bright Red" dye in finally, & its much closer to what I'm looking for!  :thumb:

(https://www.audiocircle.com/image.php?id=214068&size=large)
Natural, Bright Red, Perfect Red & Mahogany Red.

Next is to tone-coat the samples with different dyes to see if I can find a combo I like most!
Title: Re: Hobbs NX-Studio Build
Post by: Hobbsmeerkat on 4 Sep 2020, 12:12 pm
Heres the same samples with 3 "perfect red" tone coats.

(https://www.audiocircle.com/image.php?id=214079&size=large)

Next will be fresh strips coated with "Bright Red" tone coats.
Ill also do a 3rd test with "Mahogany Red" tone coats after that.

Test batch #2!

(https://www.audiocircle.com/image.php?id=214111&size=large)

Top: 3x Perfect Red coats
Bottom: 4x Bright Red coats

I personally like the Bright Red base with Perfect Red tone coats.
The Bright red only is a little more "warm" red, with the BR+PR is a little more balanced. Imo


(https://www.audiocircle.com/image.php?id=214112&size=large)

My dad seems to like the PR only strip most, but I think it's mostly cuz that strip has more of the curl in it.

This is gunna be a tough pick lol
Title: Re: Hobbs NX-Studio Build

Post by: DonJoe on 6 Sep 2020, 05:39 pm
Those darker finishes remind me of the B&W Signature 805s they made years ago with a red birds eye maple.  It was a great looking speaker in terms of finish and I am sure yours is going to look and sound even better.

That is really nice looking for sure, i really do love the look of birdseye maple, esp with really deep wine colors like burgundy.

(https://www.audiocircle.com/image.php?id=214450&size=xlarge)

This is how they appear in my room under the diffused lights rather than using indirect sunlight or a more singular source.

Still leaning towards center-left, tbh, but its a tough choice, cuz center-right looks good too..

I've also wanted to start working on flattening out the veneer, now that I've got the supplies I need, but the weather lately has been absolutely atrocious, with constant rain & ultra-high humidity. Also, with the product I'm using to flatten the veneer, this process really needs to be done outside for adequate ventilation.

So hopefully things will clear up soon so I can finally get started..
Title: Re: Hobbs NX-Studio Build
Post by: hawkeyejw on 12 Sep 2020, 01:40 am
Not sure if it’s Just the variation of grain pattern but center right has some really cool depth.
Title: Re: Hobbs NX-Studio Build
Post by: Hobbsmeerkat on 12 Sep 2020, 02:19 am
It's definitely a variation in grain pattern.
For these test strips, i used the edges which have areas that are far less wavy/textured than the areas in the center I plan to use for the speakers themselves.
Title: Re: Hobbs NX-Studio Build
Post by: hawkeyejw on 12 Sep 2020, 07:11 pm
Got it. I think any of them applied over the whole speaker will look great.
Title: Re: Hobbs NX-Studio Build
Post by: Hobbsmeerkat on 12 Sep 2020, 07:23 pm
For sure! Im still not 100% sure if I want to do that yet though.
I'll just need to take a closer look at my sheets and figure out what layout will work best. Im still debating on going with a black front with veneer on the sides/back/bottom.

But ill definitely be showing my progress one way or another!  :thumb:
Title: Re: Hobbs NX-Studio Build
Post by: Hobbsmeerkat on 16 Sep 2020, 02:27 am
Okay, I think I've found the color Im going to go with!

It's actually a hybrid of roughly 50/50 Bright & Perfect red for dye & 65/35 for tone coats.

It's the bottom-right sample.
Its got plenty of depth, without being burgundy or too bright.. :thumb:

Still hoping weather clears up this week like its supposed to so I can cut & flatten the veneer to start making progress again.
The gulf & atlantic have been incredibly active with storms the last few weeks, hopefully this week we'll finally get some good weather soon. *crosses fingers*

FINALLY!  A day without 100% humidity and rain!

Got the first 2 sheets of veneer flattening under plenty of clamps & pressure. Ill check them tomorrow to change the paper towels and hopefully finish drying it out perfectly flat.

Title: Re: Hobbs NX-Studio Build
Post by: Hobbsmeerkat on 19 Nov 2020, 03:43 am
Between weather and life in general, I haven't been able to get far with the veneer, and flattening hasn't been a particularly fruitful endeavour..

The outsides look good, but the middle has tight ripples I cant get rid of, so I'm trying one more time, but I don't really expect much to go any different. I suspect I just can't apply enough pressure esp in the center to prevent the ripples.

I may have to call around & see if a carpenter in the area can flatten it for me, or even apply it to the cabinet..

But in the meantime, I got the flush bit Peter recommended in his XLS veneer video, and trimmed/sanded down the ledges/edges.


I'm only planning to paint the front in a matte or satin black, so I rounded over the top front edge & it honestly looks really nice.

Ill check the progress on the veneer again tomorrow but I'm not particularly hopeful, but only time will tell.

What brand/kind of veneer will you be using?

I hope it goes well with your build!!! I will check in tomorrow night. I will start my build this weekend. Did you purchase Danny's speaker wire? I purchased 9 feet minus the six inches on both ends for the terminals. I'm hoping 8 feet will be enough. I will mostly do near field listening, but just to be safe I bought a couple feet extra in length if I ever do move my system to a bigger room.

Its a raw quilted maple veneer. Probably should have spent a little more for some paper backed maple instead.. :P

Thanks! Ill try to write up an update sometime in the morning tomorrow.

I did! Im currently using them on my X-LS.
I ordered 12-ft of the 16-strand cable which when the rope is inserted made both lengths roughly 5'4" which is just long enough for my current desk set up. When I get ready to work on building a longer pair, i plan to order about 22 ft or so, which should give me closer to 10ft per side.

Hope Depot. Tho I should have gone with 3/8" or 1/2" rope instead of 5/8" just to make it a little easier on myself, its a little tight for the 16-strand cable.

Hope depot? You mean home depot? If it's not too much to ask could you send me a link of the rope you bought? Thank you for the advice!! I was actually thinking last night how much length I would lose if I bought something too thick.

Ye, Home Depot. My bad. lol
Uhh... I bought it in store so I didn't need to buy a 200' spool. I just got 10" and trimmed down the excess.
Here's the specific item tho: https://www.homedepot.com/p/Everbilt-5-8-in-x-200-ft-Polypropylene-Solid-Braid-Rope-Black-72650/206094558

You loose a little over 2" of cable length for every foot of 5/8" rope.
If you use something a little smaller like 3/8" or 1/2" rope you'll probably be closer to under 2" per foot.

--

Checked on the veneer again and its still got that heavy center ripple..
So I guess ill start calling around to seeing what my options are.  :roll:

For anybody reading this with the speaker wire don't get 5/8. Get the 1/2 like I did. It's easy to run it through. Though the cord may come untangled at first due to the ends of the speaker wire poking at the cord. Make sure you isolate the ends from the cord when feeding the cord.

I actually put electrical tape around both the ends to prevent it from unraveling. It worked prefectly for me, & made sliding  the rope thru a little easier, despite it's tight fit.

But I'll definitely plan on using 1/2" rope once i make a 2nd pair for a more dedicated listening space. :thumb:

Hobbs, thank you for the advice in regards to the speaker wire.
Again I originally purchased 9 feet from Danny 16 strand. I purchased 1/2" cord and I "lost" 1.5 feet. I have 7'5" feet to work with which is enough for my room. I did use masking tape on each end and it did help.

Good news on the veneer!
I changed up how I clamp the veneer, mostly removing the outer clamps to focusing on just the center, and that has really helped flatten those ripples out.
Now I'll focus getting a 2nd set of veneer flattened so I can work on gluing it to the sides of the cabinets.  :thumb:

The wire is already braided, you just need to feed rope into it. Then separate the different colored strands at each end to terminate into connectors.

Danny has a great video showing the assembly process here:

General update so I can keep tab on things that are either in progress or working on down the line.

Veneer:
Glue & flush trim the first batch of veneer.
flatten 2nd batch, repeat for back side.
Stain, tone, & clear w/ lacquer.
Prime & paint all remaining surfaces. (Face, top/slope & bottom)

Top grill:
Prime & paint black
Cover with black cloth.

Crossover plans:
Sonicaps & Miflex Copper bypass caps
Path Audio resistors
Erse 14AWG foil inductors

Servo sub stands:
Danny was looking to sell a pair of them when I visited last month, & the OB setup should compliment my Studios really nicely where/when I can listen to them in the unused family room, since it's a spacious room with a vaulted ceiling. (I dont remember if they're dual or triple 8" subs tho) I'm really excited for these! :thumb:

(I was really tempted to buy his X-Omnis from him too... :lol:)

Cables:
I plan to purchase another set of Danny's 16-strand DIY kit, but for use in the main room, probably doing 8-10' runs. Bananas & Tube connecors.

Etc:
Awaiting availability of New NQ woofers to place the order.
No-rez for inside & upper slope.
Assemble & mount crossover
Quick setup & listen in room before 40-100hr break/burn-in time.
Then finally, enjoy.

Thank ya both! I'm really happy that im finally making good progress on these!

Hopefully i can get to work on flattening the next set of veneer tonight, and have that glued to the 2nd speaker by the end of the week. So I can start work on the back/bottom and get them dyed/stained, tone coated & cleared asap before latent moisture becomes a problem. Thankfully, a cold-front is moving in today which should mean cool dry air for the next few days.

The M165-NQ is the standard woofer for the studios and the NX series, tho most use the 16-Ohm version in parallel around the tweeter.

The model that should hopefully be arriving in the next couple weeks is a little different from the older versions that have been used until now The phase plug is more rounded than pointed, and the back is flat. According to Danny, when I visited back in October, the response on the current production run is a little bit smoother than the older models, but is otherwise identical.

I just started building the same kit and I'm already wondering what to do with the electronics.

The values of the electronics are all chosen by Danny and are already included in the kit along with the wiring diagram. But you can also chose to pick out your own parts if you wish.
That said I can imagine that the base kit with Sonicaps, Mills resistors, & air core inductors is already a fantastic way to go.

My choice for Path Audio & foil inductors was based on a couple different upgrades by others on the forum who have also done the same/similar upgrades in the past. I havent ordered them yet cuz I want to verify their values before purchasing.

But yes, essentially I wanted to get the best I can reasonably afford, hence why I'm passing on all copper caps, and going with Sonicaps & Miflex copper caps instead.

Nice job so far on the monitors, that finish is going to be beautiful. Looking forward to hearing what you think of the Statics too. Do those have upgraded crossovers?
Title: Re: Hobbs NX-Studio Build
Post by: Hobbsmeerkat on 1 Dec 2020, 03:50 pm
Ive listened to them for about an hour or so, with a single servo sub stand in the middle.

But so far they sound great! The mids are really clear & spacious, and since they dont play down very low, they offer plenty of detail.
That said, it does lack a bit of clarity and depth in the treble that my X-LS have, so I'm guessing its still the stock crossover.
But there are songs that sound better on these than my X-LS

The subs are really fast with lots of detail and easily hit into the 20s  without the boom of my 12" Rythmik, I'm definitely excited to hear them running as a pair in the future tho! should help with the low end extension a fair bit. The lowest notes in Boz Scaggs "Thanks to You" are just a little thin, so the 2nd tower should help.

I've got their placement about 5' into the room, crossing just behind me, but I still need to dial in the sub a bit more. Depending on how I'm sitting the bass is either full or drops out. It's likely playing up too high, causing cancellations at the listening position.

Unfortunately one of the X-statiks was damaged in shipping, but I'm working with the seller on filing an insurance claim.  I've sent a message to Danny to ask about possible repairs. Luckily its not catastrophic. but still a bummer.  :(

(https://www.audiocircle.com/image.php?id=217699)

I would love to upgrade/replace the crossovers & add a pair of tube connectors in the future tho.

Having owned and upgraded several X-series speakers I could easily identify what you're talking about.  It's kind of a graininess.  Sonicaps are much cleaner sounding. 

Here's a shot of my upgraded X-Statik crossover with Sonic Platinums and Gen 2 as bypasses.

(https://www.audiocircle.com/image.php?id=217709)

My Statiks also had some flexing of the open baffle section during shipping.  Fortunately the Moho veneer does a good job of hiding it. 

(https://www.audiocircle.com/image.php?id=217710)

BTW, if your 12" sub is boomy then it's not dialed in right.  Or it's in a bad spot in your room.  There should be no boom unless it's in the recording.

Yeah thats likely the case, i dunno if grainy is quite the right word, but but there's definitely a softness or veiled aspect to the sound.

My XLS just has the base kit with tube connectors, but i know it's already a head of the game in terms of overall quality. So ill probably order the sonicaps as upgrades, or go all out and do point to point wiring with the bigger inductors.

Hah thats interesting that your crack pattern is nearly identical to my own. At least yours does hide it really well.

I may do it "right" & replace the whole front baffle, or i may go the easier route and just sand it down and fill & seal in the problem spots then paint to match.
But I know if/when it gets shipped in the future, another hit like that will likely destroy it totally.. unless i can come up with an easy way to reinforce it & still remain hidden under a fresh coat of filler & paint.. or reinforce it before shipping..

It's no longer boomy since I've gotten it dialed in, thankfully. That said, it still loads the room differently than the OB servo stands, which still do a great job once they're dialed in.
After I get that room a cleaned up, (cuz its a total wreck now) I want to get both stands up and playing, cuz there's not quite enough room at the moment for both, unless I move the XStatiks aside and put my X-LS on the stands.

I have tried that before, but it didnt really make much difference, sadly. But I'm sure i can get it worked out its just gonna take some time.. I've made progress since last night thankfully, but not ideal.

Steam isn't recommended tho, since it will cause the veneer to swell.

I have in the past, sprayed wavy veneer with super soft the night before applying. Then give it a spritz with super soft just before applying it to the substrate the next morning. This was done using Veneer Supplies Heat Lock glue, and it has come out flat and is still in place to this day. I just started in the middle of the panel and worked out to the edges. You do take a chance though of the veneer splitting when being force flat with the glue and a hot iron. If it does not work it is hell trying to get the veneer back off, just to warn you.
Title: Re: Hobbs NX-Studio Build
Post by: Hobbsmeerkat on 5 Dec 2020, 01:30 am
Yeah that's basically what I did with the first speaker.
Tho I'm not using heat lock adhesive, I'm just using their standard veneer glue which requires pressure for the first few hours, with pretty decent results, but it really takes some doing to get the veneer flat, & there's still a small bit of ripple in the middle, but its not noticable thankfully..

Pressing out the ripples really takes some doing. Checking on the veneer this evening, it's looking better, but its a slow process..

I need to find a better means of flattening than plywood 2x2 rods & clamps. But I'll get there! lol

I know nowhere near as good as real purpose-built tools, but maybe an aluminum or steel plate instead of plywood?  Wandering down another hobby/tangent, a 45lb old school deep dish machined cast iron weight plate or a calibrated 20kg or 25kg steel weightlifting/powerlifting disc at 450mm diameter might be just big enough to do the job that might be handy to get if you don't have a lot of manufacturing or fabrication shops around where you live?  A pair of plates and some clamps could make for a nice big flat press?

Thanks so much! They've still got a long ways to go, but i've finally made some good progress with the veneer and have the first side, being glued onto the 2nd speaker! Hopefully i can have both sides finished today, & work on the remaining sides here soon.  :thumb:

Nice! Quality sheets of Quilted Maple certainly arent cheap, but if my dye/tone samples are anything to say about it, 100% going to be worth it onces its done.
Getting the right "Red" was tough but, I'm excited to get these finished soon!

And I'm glad I could inspire you to do something similar with your own pair of XLS! I love my pair of XLS, but they were always meant to be a stepping stone for my Studio build, even if my original plans for the veneer was a stained walnut, with a gloss black front.

I really recommend watching Peter's video on applying veneer to his XLS kit and using heatlock glue & paper-backed veneer instead, will be a lot easier to work with, since it wont require any clamps.. :P

Hobbs:
Use multiple  clamping cauls to evenly spread the veneer clamping pressure.
A  Caul is a simply a  slightly tapered  clamp block that redistributes the clamp pressure from the clamped edge to the center of the panel.
Google ‘clamping  cauls’  for creation and use  instructions.

If you are using an intermediate  melamine veneer pressure plate, the absolute caul quality does not matter nearly as much as for a typical full edge tabletop glue up .

The dye is still wet, so the colors are still vibrant, it'll fade more purple/, but once I start adding the tone coats it'll come back really strong. Tomorrow I'll pick up some filler to hide the step/edge of the veneer.

Feels good to be making progress again.  :thumb:

Exactly! I need to give this one a day for the lacquer to cure before sanding & another coat. After that all remaining coats will be clear coats. Hopefully over the weekend I can coat the 2nd speaker, but it needs to be a day when im off so i can take advantage of the warmer weather, otherwise I risk the lacquer turning cloudy.

Here's how it's looking now.

I've also started working on the grills for the top, both have been primed, & one has been painted, ready for applying the grill cloth.

Nice work Hobbs. Can't wait to see it with a few coats of clear. I would also give it a cut and polish at the end once the final coat of clear is hard enough.

Thanks y'all! I'm really happy with how they're coming along!
I definitely plan to cut the current layer to hide some of the ripples before applying another tone coat & going clear from there once the rest of the speaker is ready for top the coats to hide seams.

I'm really happy with how nicely the color pops, quilted maple was definitely the right choice, much of a pain as it is to work with.. :lol:

Now that my mini vacation is over progress has haulted, aside from spraying the grill frames, may give them a light sand & another coat with the magnets intalled for easy removal.

Still got a long ways to go, but its all coming together~

Both cabinets are tone coated, but still need a few more layers.

And in the process of working on these I learned a neat technique today that will replace the issues with sanding.
It's basically taking a razor & scraping along the length of the cabinet to flatten out the surface by taking down the high spots. Wish I had known about this technique sooner, but hey it'll make my life a little easier going forward.  :thumb:

Hopefully Sunday I can make some more progress!

Hi Hobbs,

How are you planning to install the NoRez?  If you already had it on hand, would you have chosen to install it prior to completing the boxes?  I assume it has to be cut into smaller pieces to get through the woofer hole if installing after completing the box.

I have the flat pack but not the speaker kit.

Thanks!

I think I would still plan to apply the norez after assembly.
I did the same with my XLS build.
And that is largely since its easier to glue up without having to worry about the norez being in the way.
It can be a little more cumbersome to apply after assembly, but I dont mind cutting the Norez into smaller strips, its fairly easy to do with a sharp razor or bow saw blade

I dont have the speaker kit either tbh. I'm still waiting on availability of the next batch of NQ woofers.

Small update!

Done with tone coats! Now onto preparing the rest of the speaker!

I used wood filler to help hide the edges of the veneer, and fixed some small dings caused from frequently handling them for the tone coats, sanding, etc.
Used de-waxed shellac as recommended by others to help seal the MDF, tho the edges were far too absorbant, even after several coats. So I switched to a latex-based sealing primer for those sections, which has worked really well!

And how they're in the process of being primed!

Hobbs, I'm curious about the "latex based sealer/primer". What is it? My experience with sanding latex paint is it's  like sanding an inner tube. OK maybe not that bad, but you get the drift. Do they give a "dry enough to sand" time?
Title: Re: Hobbs NX-Studio Build
Post by: Argoncat on 3 Jan 2021, 02:02 am
I used a two heavy coats of dewaxed shellac sealer (zinsler) followed by a 2-part high build epoxy primer 70-80 um layer all MDF parts. (Taken from the auto body world)

https://www.amazon.com/gp/product/B00B3I2E8E/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

Ventilation is key, this is certainly nothing you want to breath or saturated your kitchen...  light sand with 800 grit followed by a few coats of black on top followed by the spray max 2k matte clear coat..  hope this helps

It's the Valspar bonding latex primer. It says it has a "30min dry time," but thats likely more "to the touch." i gave it 2 layers and let it for 24 hours since i had plans for the evening and work at 4am..
I sanded it with 600grit to smooth the texture from the brush i used, but It actually sanded really nicely. No gumminess or clogging, thankfully. I used it on all exposed edges and it does a pretty good job sealing over the open fibers and allowing for a smooth finish.

Hobbs, sorry to jump in here but I have a suggestion for Peter.  If you are going to use a latex paint as a sealer/primer I recommend using a flat paint. That might solve your sanding issues.   Or better yet, Sherwin Williams has a latex product called Premium Wall and Wood Primer. It sands very nice.  But the best stuff to use IMO if you don't mind the set up time, smell, and have the ability to spray is a white lacquer undercoat.  As you may know cabinets are often sprayed with a lacquer sanding sealer before they are stained.  For paint grade house trim some painters will spray the pine or MDF with a tinted lacquer undercoat so they will have an easy time sanding the trim smooth before applying paint. 

 Sherwin Williams used to carry a product by GSW paint called Bushwhacker which was a nice white pigmented lacquer undercoat but I can't find it locally any more.  I finally found a product by PPG paints (their house paint stores not their auto paint stores)  called Speedline Lacquer which is a white lacquer undercoat and it sands beautifully and allows you to build up a very smooth base for paint without breaking the bank.

Lastly, to keep MDF from soaking up the paint or sanding sealer I know painters that take drywall compound and basically smear it into the pours.  I'd use the powder drywall mud and play with the consistency by adding more or less water.  Sounds like a hassle but it is really quite easy. Drywall mud sands really easy as long as you buy the right one.  They have a few different types.  Little longer than I planned but hope it helps.

I'm just not a latex kinda guy, preferring nasty solvent based primers and top coats. But I am curious what others find useful. I've read of folks using drywall mud, but it is really ill suited for the task. Hot mud (powder) would be a little better but when better products exist I have to ask why? To me, painting a speaker cabinet has little in common with house painting.

 Lacquer is another story. There's lots to like about it from my point of view, but less and less available to consumers. Sherwin Williams has an industrial coatings side, but not all stores carry it or even know it exists.

Rain on my previous day off, Sunday, prevented any progress so I made some progress today instead!

(https://www.audiocircle.com/image.php?id=219235&size=large)

I plan to do some more coats over the next couple days, with plenty of drying time in between. This is a satin black, and its pretty cool getting to see it finally all coming together!

Once im happy with the coverage, ill pull off the tape and begin coating the whole cabinet with clear spray lacquer, and probably by brush for the shelf/rear baffle. Since getting any sort of coverage in there has been a big test of my patience.. lol

That looks promising.

Do you sand down the surface after each coat? I have no experience with this but that's what I saw in several YouTube videos of people who looked like they know what they are doing.

Not after each coat, but i did do it once after i was starting to finally see full coverage, with an abrasive pad, and ill probably do it again before I lay down the next coat. And before I plan to finish it all with clear lacquer.

I’m planning to use Minwax Sanding Sealer for my base coat on the MDF.  I already sanded the MDF down to a pretty good surface quality.   I bought Krylon satin finish paint but am second guessing that decision.  The plan was a dark baffle with light colored panels.  I have a large supply of high quality sandpaper, all grits.

When you start cutting the NoRez, do you mind documenting the dimensions for the pieces?  I forgot to measure the box pieces before assembling them.  Otherwise, I’ll probably just cut up cardboard pieces and go through the guess and check iterations.

Thanks!
Title: Re: Hobbs NX-Studio Build
Post by: jonsk2514 on 8 Jan 2021, 01:05 pm
How were you thinking of applying the Krylon?  I would suggest trying it on a practice piece first.  I used Krylon satan black for the back and bottom of the cabinets I am building.  This was applied with a brush and I found that it didn’t level much at all and brush marks were left when it dried.  I suppose that, if applied with a roller, it would leave a nubby texture.  That could an interesting.  As a simple way to finish his smaller speakers, Danny showed how using a roller with the black he sells results in a similar finish.  I considered that sort of finish for mine, but went with a more traditional varnish finish.
Title: Re: Hobbs NX-Studio Build
Post by: CaptainBill on 8 Jan 2021, 01:28 pm
I was planning to build it up, spraying thin coats over a few days, then sand it down.  If the orange peel gets too bad, then sand down after a few coats before I lay down some more.

Nice job with the top grill.

I keep debating on whether to use fabric on mine or not.  We have dogs and the house seems to be quite dusty, generally speaking.  I'm afraid the cloth won't look good for very long and will be hard to keep clean, especially being a horizontal surface.

I'm eager to start finishing my baffles but other plans keep getting in the way, especially on the weekends.

I don't see a problem with the fabric at all. Dusty, dog friendly environment here and have never had an issue with any speaker grill cloth. Plus the grills make for a nice finish touch. When I ordered my fabric from SpeakerWorks, the smallest option was a piece 36"x67". (well under $20) You could stretch new grill clothes for years and still have material left over. Frankly, the exposed 5" driver would be far more worrisome than a grill cloth if you have large dogs.

My fabric is moderately thick cuz it was the nicer of fhe two main black cloth fabrics, (Mellowtone) but not crazy by any means, around $25 for a roll.

the adhesive sollution I used added some thickness as well, especially around the corners, and bottom  so it sits up a little higher (1-2mm) than it would otherwise, and on the sides, its fairly snug, but it wont get stuck and can easily be pulling out with a magnet or by hand if needed, but also won't rattle or shift when I test fit them yesterday.

No, different thicknesses are available. So you have decide if you want material that's thicker and more durable or material that's fairly light weight. The lighter material will be bit more transparent if the grills are left in place. But I have a feeling most will take the grills off when listening anyway.

Yeah the main differences are mostly of either of quality or style/color You could easily get away with a generic porch-screen material if you wanted, or a nice fabric from a craft store.
Hell you could even use a plain q$5 cotton/polyester blend t-shirt from Wal-Mart if thats what you wanted to do.. :lol:

The NX Studio is definitely different that its probably the only speaker to have a top-mounted grill. (Not including the AV-O/X-Omni which some models had a front/top grill) 
90%+ of speakers only have drivers on the front. Tho I have seen some OB setups with grills on the backs to prevent children from messing with the crossover/wires.

Luckily it wasn't too bad, so i just put down some fresh glue and clamped it back into place, now I just gotta fill in the cracks with a few layers of lacquer..
Ive got the first layer on now, but it's been too cold outside to apply any more at the moment..

No kidding, it could definitely have been a lot worse, all things considered.. i remember watching a video a month or so ago on how to repair old veneer that had peeled up, and that really helped me already have a plan on how to repair them in case of such an issue.

Yeah.. once I get it resprayed I'm not gunna fuss with it, just leave it be. But thats also why I wanted to brush it on instead of spray, but it looks like the solvent in the brush lacquer is strong enough to break down the paint.

Absolutely! I had to give up the AV123 XStatik tower that was damaged in shipping in order to get a refund from Fedex. So I'm gunna use that money to build a replacement tower and upgrade the crossovers in both the new and old towers. (Sonicaps w/ copper bypass caps & mills resisitors)

I'm not trying to salt your wounds, Hobbs,  but I thought it might be beneficial to point out to anyone reading this what went wrong here.

Latex paint is very susceptible to the solvent in lacquer, which is lacquer thinner. Most anything that wasn't designed to have lacquer thinner as its solvent would have a similar reaction.

Common thinking is that you can coat over a cured lacquer based finish with water base, but the reverse isn't true. In some cases, vinyl sealer or shellac can be used as a barrier coat between dissimilar finishes, but typically that's between oil based products and lacquer. I've never tried experimenting with a barrier coat in a situation like you have, but imagine there's enough movement differential between the two that it's going to be a problem over time if not immediately.

I have sprayed lacquer over what I thought was well cured DuraTex and it seemed fine initially, but ultimately failed in a kind of spectacular way. Mike had the evidence of this, I don't know if he still does. I think he intended to strip and refinish, but I learned a good lesson. I may have photos but suffice to say I won't do a repeat of that performance.

Yeah that's something I should have considered might be an issue, so its not salt in any wounds. It's definitely a live & learn thing, and I'm okay with that, esp if it also helps other's in the future.

Luckily, spraying canned lacquer onto the front didn't have the same issues, since its much thinner and there isn't a force being applied via a brush, and it's also much thinner coats being used, but that may have changed as more coats were applied.

Ill probably try a test tomorrow with some paint coated in shellac before going to spray lacquer onto it.
Title: Re: Hobbs NX-Studio Build
Post by: Peter J on 23 Jan 2021, 03:47 pm
Hobbs, I would encourage you to rethink your plan if possible.

 Lacquer, no matter how applied, is not a good idea over latex products. Bear in mind that to get material thin enough to exit a spray can, it must be considerably thinned down...with lacquer thinner in this case. Clear acrylic or even oil oil based polyurethane might be a safer bet. It would involve less "hot" solvents. Lacquer thinner is among the hottest.

Intentional or not, what's unfolding is a bit of a chemistry experiment. Here's the failure I alluded to earlier. I don't know how long it took to manifest, because they were stored out of sight, but if guessing probably months. From a forensic standpoint, it's evident that the strata of finishes were moving differentially. Specifically I suspect the DuraTex shrank underneath the lacquer, most noticeable around bolt heads.

Title: Re: Hobbs NX-Studio Build
Post by: Hobbsmeerkat on 23 Jan 2021, 04:07 pm
A fair point, for sure. I just applied the lacquer to the shellac coated paint this morning, i imagine it'll probably look fine, but considering your issues also took months to develop, the same will probably happen down the road regardless.

Ill probably look at getting clear acrylic then.
Im assuming it can be applied to lacquer as well for a clean transition between the paint and lacquer sections?

I can't say with certainty. If each coat of differing material is viewed as a separate stratum within the "sandwich" many things come into the picture. Not the least of which are differential movement and adhesion between layers. So in some ways introducing a new element just increases the potential for failure. This is mostly conjecture based on my experience. It may be fine in the long run but, unfortunately, only the long run will tell the whole story.

I guess it kinda proves that  test sampling of something new is good practice. I wish I had a pat answer for you, but I'd be lying if I said I did. It's just the way experiments unfold.

I did some searching online to see if acrylic can be applied onto lacquer, but it doesn't adhere well and will likely peel over time. But I did find that lacquer can be applied to polyurethane so long as a layer of shellac is used between them. But ill check out the results of my test in a couple hours. It went on really easily without any pulling or struggle, thankfully.

Guess I should have thought ahead & used black lacquer, instead of a standard latex spray paint to avoid unforseen incompatibilities.
Title: Re: Hobbs NX-Studio Build
Post by: Hobbsmeerkat on 23 Jan 2021, 06:55 pm
I checked on the sample and its looking pretty good. It's dry to the touch, but still needs some more drying time before it's fully hardened to see if any cracks or peeling forms.

With my X-Statik project still ongoing, and the delays with the NQ drivers, this build has been pretty quiet since the last update.

That said, I got my 2nd cabinet ready for some edge touch-ups before it's time to seal the cabinet and get it ready for the clear coats. Pending the weather tomorrow, it should be an easy task.

Tho I'm considering swapping out the Sonicap in the tweeter circuit for Danny's Copper Caps or go with some Miflex copper foil caps instead. But with the thread no longer being a sticky, I'm not sure if they're still available, or if the Miflex are a suitable alternative, esp since I'm already going to be upgrading to foil inductors a Path Audio Resistors.

For the bass circuit, I plan to keep the Sonicap to save a little space, (and money) and paired with a Miflex bypass.

Just curious about peoples feedback/thoughts.  :thumb:

I'm actually getting pretty concerned about that with mine.  Right now the braces provide really nice grab bars for moving them around, once the front baffles go on things will get tougher.  I'm probably going to cut a shallow handhold into the bottom with a router to give myself a more secure handhold once those go on.

I used the holes for the ports as hand holds.  Even after I “cemented” them in they still worked well for that.  The PL adhesive worked great for those.

As mentioned in a previous post, i was considering going with Danny's Copper caps for them tweeter, circuit, but it looks like there aren't any left, so I decide to get a pair of Miflex copper caps instead. They measure less 0.5% off of the mark, and are perfectly matched, which is about as "perfect" as you can get!  (Not to mention they're currently 25% off! :D )

It'll mean some extra burn in time, but considering the strong reviews of Miflex copper caps, I'm excited to see how these all come together, once the kits are finally ready to ship!

They came really well packed, each individually wrapped, in a box, then double wrapped in Fedex bubble packs.

These caps makes Dannys massive laminated iron inductors feel light..  :lol:

I'm not planning on changing the box volume tho. (Too much effort) tho If I was also getting copper caps for the woofer circuit, I'd be doing an external crossover assembly... But I'm happy just sticking with Sonicaps & a miflex bypass. :P

I appreciate the suggestion, but I already had a desire to use copper caps on these for some time now, but wasn't sure if it was the direction I wanted to go yet. And seeing them on sale was enough reason to finally pull the trigger.

You’re planning to stick with internal crossovers with those things?! How much internal volume will the entire network take up? Gonna be like lifting mjolnir trying to move those things around.

Yup!  8)
That cap is going to be the single largest unit in the entire circuit, the foin inductors are fairly tightly wound and sonicaps arent particularly large either. If I was going to use a massive copper cap on the woofer circuit, I would have to use an outboard crossover..
But I dont plan to move these around much once they're finished tho. But I'll definitely give them a weigh in once they're complete. :P

After showing Danny my over-sized Miflex cap, he recommended that I go with an external crossover, since it would take up too much airspace within the cabinet.

So I spent about 30 min this morning laying out some possible design ideas that sould work for something I can place bedside the speaker, or on the floor, as needed.

Here's what I think will work best within a roughly 8.5x10x6 inch box:

(https://www.audiocircle.com/image.php?id=225822&size=large)

Internal space will be roughly 7x8.5x4.5 inches. I left out the resistors cuz they're small and easy to place, even with 4 of them.
(They also dont make/sell the exact values I need, so they'll be run in series pairs to match what's needed).

They'll probably just be black boxes, each with 6 female tube connectors & a removable panel once theyre all finished. And a couple sets of wires for desk or stand use as needed. :P

The real trick will be drilling another pair of holes in the cabinets for the second pair of tube connectors, without damaging the veneer or blowing out the inside of the MDF.. lol

You trying to compensate for something with that Miflex cap?  :lol:

I’m curious about the foil conductors you’re using there. What brand and who sells them?

Looking forward to seeing these finished and your impressions.

I’ll add that I ordered some Vcap ODAM’s for the tweeter to try in my Studios. Have used them in amps and they’re superb.

LMAO, Nah they're honestly just A LOT bigger than I expected them to be...  :lol:
But I wanted to take these as far as I "reasonbly" could afford, plus they were on sale, and had lots of great feedback from several others here.

Plus the foil inductors are going to be an available upgrade on the site fairly soon, and they were already part of the plan to push them that next step further. I'm excited to get these finished and have them.

I'm probably going to make the crossover boxes match the towers, tho probably using figured or curly maple, tho I'm planning ahead and going to use paper backed veneer this time.. (Raw, quilted maple, while beautiful, is not a good place for a noob like me to start... But I somehow managed... Lol

Red dyed & toned the same with a black top that can be removed for maintenance if needed. Theyll probably get finished in a satin or semi gloss.

I've seen a couple people recommend VCap ODAMs lately, but I'll probably save that for another project in the future.

The amount of copper in this box will be wild.. Probably 6-8 pounds per crossover? The tweeter cap alone is 3-4lb, easy.

It'll be interesting trying to design a mounting board for these like i did with my X-statik. Esp since they came out to be roughly 7"x8" when tightly packed like in the pic. Not to mention the cap being massive... It might end up as an L-shaped board that just fits around it. Or has a sort of "cradle" built into it... Hmmm

Once i get moved into my apartment this week, i can work on designing things again.. :P

Hobbs I have such cross over envy happening right now. Not to mention they are going onto  :lol: the NX studios. I just want those caps to look at all day. Sad I know but the drool Hobbs the drool..... :lol: :lol: :lol: Got to love a Miflex the size of an orange.

I would, but I've already got my dual 8" Servo sub stands. plus i need to be able to adjust the length of cables im using, depending on how/where i have them set up. (i.e desk or in the room)

Trust me, if Soniccraft sold the smaller 250V versions, that's the route I would have gone. Partsconnexion does sell them, but doesn't offer matched pairs.. (at least to my knowledge)
So 600V monster cap it is.. :P
But yeah, I totally understand.. its a whole lot of beautiful copper parts to oogle over~ 8)

I forgot to answer Tomy's question about the foil inductors,
They're mafe by Bridgeport Magnetics. Its the brand that Danny currently stocks for the NX line. We just got the foil inductor for the Studios in last week, abd will be an upgrade available on the site soon once we get out from under the backlog of current orders, and parts shortages that are really holding us back.

Is that inductor upgrade a ‘must-have’? I just placed my order for the Studios today, and waffed on the upgrade. My sensibility says that in my untreated family room, I’d likely not even notice. But I don’t want this to haunt me! Is the upgrade strictly for the audiophile who might appreciate such minutia?

None of Danny's kits need an upgrade. His base kit is far superior to what you find in most commercial speakers. The upgrades are beneficial but how much you will realize depends on the capability of your electronics. If you have a budget level system you won't notice as much of an improvement as you would with a mid-fi system. High end systems give even better performance.

On the one hand, fully upgrading the crossover components will give you a speaker you will never outgrow no matter how good the rest of your system gets. On the other hand, if you start with the base crossover components then later on upgrade the rest of your system to a much higher level you can always build another pair of crossovers with better parts.

Mike has it right.
My kit is wildly overkill, esp for my system as it stands currently, but I'll never have to worry about it being the weakest link in my system.

For anyone curious about the difference between the original NX studio Danny built vs the first production run by Jay/Captainhemo,
Here's a quick side-by-side comparison of Danny's build vs my own.

(https://www.audiocircle.com/image.php?id=226363&size=large)

(https://www.audiocircle.com/image.php?id=226364&size=large)

Danny said the differences in design dont make much difference to performance, but the current production runs should be a little more similar to the original design, mainly raising the tweeter and woofer about an inch or so it's further from a desk or console it may be sitting on.

I still haven't had a chance to purchase my own kit yet, but I have the parts I need set aside once we get caught up on the current backlog of orders as best we can. Gunna spend the weekend pre-packing a ton of orders and making invoices so that come Monday & Tuesday, We can get a good chunk of them out the door while we have 4 people in-house.

But I'll be sure to update you all once I get my kit and start assembling my crossover and planning out the building/veneering of it's box.  :thumb:

Yeah,  I actually did both designs  of the Studio's .  When we donated that pair to Peter so  a build could be done to present to Danny,  he (Danny ), measured them   and they measure  fine, basically  the same  as  thebaffles   only   he had  cut.

After   a number  of  folks asked aboiut it and most   said they felt   the  higher tweeter/woofer  looked better  (guess my taste  sucks !),   we've  done a n alteration  and  are now  shipping,  I guess youi could say,  the MKII.

Tweeter/woofer have been rraised and we're  adding roiundovers to all external edges of the   grill frame.  I"m still debating onadding  a  7/32  wire pass through hole  to the  plate right below the tweeeter.... problem is if I put it in the center ,  there will be folks  who  want it on the  side.... and the opposite applies as well.  May just  leave as  with no wire pass through and folks drill one  where they  want  it.

Will try and get  some  pics posted in the flat pack thread later  today...

I went and found the cheapest available parts I could find on Parts express that will work for the NX studio crossover.

(I could have gone cheaper for a few parts like the iron inductor, main cap, and shunt resistor, but I'd be waiting a few more weeks to save like $15)

I did get a Dayton bypass cap, but I'm gunna wait to install it later.

I also snagged some super-cheap brass/nickel banana binding posts with an steel nut, and some 24-gauge zip-cord wire to act like your typical internal speaker wire..

Just having a little fun~

I'm still learning about such matters, but is the bypass cap still necessary when the primary cap is of equal or greater quality?  I am of course referring to that beer can in your network.  When I did my Otica build, I opted to upgrade the mid circuit to soniccaps, which had a small bypass cap on the base kit.  Did I even need to include that tiny cap?

Title: Re: Hobbs NX-Studio Build
Post by: Norman Tracy on 18 Aug 2021, 06:47 pm
Swooping in with a thread-jacking, now its all about who's got the most out there crossover.

Contender #1 -  Kawero! Vivace Supreme crossover with the best silver/gold/oil Mundorf capacitors and VertexAQ structural acoustic absorption techniques together with VertexAQ radar absorbing material to reduce Electromagnetic Interference. And just for good measure Panzerholz plywood for the mounting structure. 100% maniac.

(https://www.kaiser-acoustics.com/en/speakers/vivace/vivace-components__340.jpg)

Contender #2 - BØRRESEN crossovers using foil inductors (na na na na GR got there first) but unique to my knowledge in speaker crossover application surface mount plastic film caps. The black and silver boxes soldered to PCB beside the front inductor. These eliminate the inductance of the lead wires but are a BITCH to solder, over heat just a little bit and the metalized plastic layers melt and cap goes open or suffers wild value changes.

(https://www.borresen-acoustics.com/images/2021/02/09/borresen_delefilter.jpg)

Contender #3 - Living Voice's Auditorium range of speakers use exactly the same driver set and box and as you go up the range what changes is better and better crossover parts. This tops out at the Auditorium OBX-RW3 where the parts in the crossover have gotten so big they require their own enclosure about 50% the size of the speaker it serves.

(https://www.livingvoice.co.uk/assets/images-auditorium/900/obx-rw3-090-900.jpg)

And now back to your regularly scheduled programming.

To some extent? But it's actually been a learning experience more than anything. Getting to play with high end hardware, amps, DACs, cables etc. is fun, but it helps me understand the things Danny, Ron and others talk about beyond just a conceptual level. I can see how changing cables on a DAC alone can help/hurt, how tubes affect the sound/tone. Differences between OB/sealed/horn speakers.
There are times when Danny is testing a speaker and I'm starting to pick out when a tweeter or woofer sounds odd.

And all that knowledge helps me relay that information back to customers based on my experience.

I've also had these parts set aside for probably close to 5-6 weeks now waiting for Danny to tally up my total since I was piece-mealing it together rather than just getting a standard kit, so there's quite a few other kits that got foil inductors long before I did. lol

That said I did also get one of the early samples of the new 10W chip amps, just need to get a battery and charger to power it. We've had one of them playing in-house for a few days now and it honestly sounds fantastic, incredibly clean and detailed with excellent bass control. It's one of the few things Danny has said are one of the best sounding devices, esp for "right out of the box." I'll be pairing it with My Studios for sure.

Not quite sure on the release date for those yet, but I believe we just gave to go ahead for making the remaining models.. should be about 25-30 units available once we're ready to release them.

I'm still learning about such matters, but is the bypass cap still necessary when the primary cap is of equal or greater quality?  I am of course referring to that beer can in your network.  When I did my Otica build, I opted to upgrade the mid circuit to soniccaps, which had a small bypass cap on the base kit.  Did I even need to include that tiny cap?

The bypass cap is intended to act like a siphon, allowing the larger cap to discharge much faster. By design, most copper caps are fairly slow to discharge due to the limitations of the materials, and without a bypass, it will tend to smear the details. And keeping the brands/type the same allows them to keep their tonal quality while also increasing the speed of the cap.

Sonicaps are really fast discharging caps, but adding a copper bypass imparts the tonality of a copper cap, leading to a more warm/rich tone.

The real drawback tho, is the amount of burn-in they require, often 400+ hrs before they settle into their final sound. When they're not ready, they often sound really hard, if not harsh.. Most of the dramatic changes will occur within the first week, with them slowly opening up and relaxing the remaining time.

According to some, as you feed them higher quality music or give them a cleaner signal from a bette qualityr front-end, the more they will continue to open up.

As for your bypass caps, yes. Both the base model and upgraded model have bypass caps included in that circuit, as it still helps them to discharge faster than they would on their own, esp once you start getting into those really large values. On smaller values like say 1-7uF its not going to be as necessary, unless there is a tonality you want them to have ontop of their speed.

@Hobbsmeerkat, I have Sonicaps upgrade in my Mini's, would a copper bypass work to get a more warm/rich tone?

Theoretically, but I don't think it's really a practical upgrade for the Mini, esp since they're $20 a piece. The Mini is also a more entry level speaker, and I'm not sure if there will be much benefit, esp if you have the Erse cap with sonicap bypass. If you have the full $50 sonicap upgrade and tube connectors, then I would probably consider it.
Much like we dont offer them as upgrades for any other speakers, unless specifically asked for, which to my knowledge, has only happened once, namely with a Sony SS-CS5 a week or so ago.

That said, it would make you the only person with such a kit, just be ready for a 2-ish weeks straight worth of burn-in. :P
They'll definitely be a bit harsh until they finally start to relax a bit.

For sure! It's actually nice not having to spend a ton of money to get the hands-on and practical experience, to better understand what is it i'm doing, and how I can apply that information, and explain it as best I can.

I don't really wanna be in videos... :lol:
I would be okay doing a stream with Ron & Danny maybe?
I'm better suited to a more text-based format, where I have time to formulate my thoughts.. Plus I don't like hearing my own voice.

@Hobbsmeerkat, You do have the dream job.

I do have the $50 upgrade. I dont have the tube connectors yet, I'm going straight from crossover to the amp output connectors. And I will go for the speaker wire kit down the road also. Now that I have the DAC in the system I can hear stuff i haven't been hearing. Every day the system seems to sound better. The bass seems a lot more full now. I don't mind the cost, I just want the best I can get because this is going to be my main system for several months or years. I do have an upgrade path so I will improving the system as time goes on.

Anyway thank you and good luck on your project.

Not really, it just needs a signal going through them. I usually keep the speakers running all day on the weekends at a low level for a few weeks. Copper caps don’t start opening up until well past 100hrs. The initial break in of the speaker will require a moderate volume level though for the first 50hrs to get the drivers relaxed.

Hobbsmeerkat that is very well done. BTW when I posted the other over the top crossovers on this thread's previous page it was not apparent just how big those coils &  caps are. Awhile later Danny held them up in a GR YouTube video and I had a  :cyclops: moment, followed by  :drool:.  I suggest for the next picture show this bad boy next to something like a woofer or the NX-Studio it will serve to better show the scale.

Hobbs that is still the 800lb gorilla of a crossover. And I like the way it looks and would want to showcase it to be seen.

I was originally gunna build boxes for them, but I scrapped that idea and went with this instead. My wiring/soldering skills aren't the best, but I'm happy with them, considering

I just finished the 2nd one last night to boot!

Hobbsmeerkat that is very well done. BTW when I posted the other over the top crossovers on this thread's previous page it was not apparent just how big those coils &  caps are. Awhile later Danny held them up in a GR YouTube video and I had a  :cyclops: moment, followed by  :drool:.  I suggest for the next picture show this bad boy next to something like a woofer or the NX-Studio it will serve to better show the scale.

I knew they were going to be big, but I didn't expect soup can size caps. I would recommend anyone else go with the 250V KPCU03 versions since they're about 1/2 the size of these monsters.. lol

I think they weigh about 8.8lbs now.. or a gallon of milk/water.

Sure, here ya go!

Next is to finish up the changes to the cabinet.
Namely, drilling another set of holes for the tube connectors, holes for the tweeter wire, and a few more clear coats and lots of wet sanding.
Then finally installing No Rez, wires and the drivers.

Getting close! :green:

Where can I buy some Liter size Soda Caps?  :lol:   All jokes aside, your project is coming along nicely.  Just let me know, when you want me to build you a awning for those puppies, to keep them safe from the elements!

They're 99% finished!  :D

I just need to paint the screws for the woofers, and make some cables to connect them to the external crossovers. (on floor)

It's been a long journey and a learning process for sure!

But I'm excited to finally be getting these babies finished!  :thumb:

September 22. 2021 - Danny publishes video Biamp and Biwiring! We NEED to TALK! https://youtu.be/908BWw1Bx4U (https://youtu.be/908BWw1Bx4U) on why you're a big dummy if you have bi-amp terminals on your speaker.

September 23. 2021 - Hobbs posts NX-Studio build demonstrating (due to crossover that would consume 78% of speaker's interior volume) when you must have bi-amp terminals on your speaker.

Maybe, just maybe, Danny will forgive you if all connectors are Tube Connectors.

Kidding aside, this over the top NX-Studio with Servo-sub stand is a perfect example of the point Danny makes in the second half of the Biamp and Biwiring! We NEED to TALK! video that where biamping really delivers in home HiFi is the subwoofer to main speaker handoff.

GR Research should name this NX-Studio + sub stand configuration and market it as a small footprint big sound solution for when the other NXs would dominate a room's acoustics or aesthetics.

Excuse you, it's bi-wiring AND bi-amping :wink:

Oh don't worry, this whole setup uses a whopping 5 sets of tube connectors. 3 for the crossovers and 2 sets for the speakers...

(https://www.audiocircle.com/image.php?id=230132)

I could have made it 3 sets, but I wanted the ability to swap the lengths in the future as needed. Plus I can test out different crossovers which I plan to do with my "el-cheepo" pair that are 5% roughly the cost of my "Overkill" crossover... lol

Small gauge wire, steel banana plugs, tiny 22 gauge zipcord...

Now to let them burn in.  :thumb:
(They already beat out the N-3s beside them.)
Title: Re: Hobbs NX-Studio Build
Post by: Hobbsmeerkat on 19 Oct 2021, 03:23 am
Burn in is complete! :thumb:
They currently have a little over 500 hours on them.

So I brought them over to see how they sound on Danny's system, as well as how they compare to his original models..

(https://www.audiocircle.com/image.php?id=231020&size=large)

We listened to them for almost 2 hours throwing everything at them, and we're both really impressed with how they sound.
Danny got goosebumps multiple times and was blown away by how well they sounded, and how clean and natural everything felt.

Everything just sounded incredibly rich and organic without losing any detail. It's just too easy to just get lost in the music.

Danny says they're the closest he's ever heard a mini monitor directly competing with the NX-Otica and NX-Treme.

I still haven't had a chance to listen to both versions in a direct A/B comparison yet but so far, I'm incredibly happy with how they sound, they hit every mark I set out for them.

I've already told Ron he has my blessing to borrow them, and he told me I wouldn't be getting them back. lol

If I were to do it over again, there are definitely some things I would change to save some money and keep the crossover inside the speaker..

But I dont regret a single thing.  :green:

Ill post another update once I've had a chance to properly compare them.

What?  No maple stands with thick brass feet for the crossovers?  Surely you can do more than just set them on the carpet.  :lol:  :thumb:

Looking forward to this. For me, swapping out the Sonicap/Miflex on the tweeter circuit for a VCAP ODAM /Duelund JDM silver foil bypass significantly improved this speaker. All while keeping the physical cap size small so it doesn’t mess with the cabinet volume.

I do have some small stands for them but that's just another thing I would need to carry around.. So I left them at home... :lol:

It would be interesting to see how mine compare to yours as well.
The intention for mine were to make it a more relaxed tone, while still offering plenty of detail and clarity without being overly analytical.
And that's been my only concern about the VCap+Deulund bypass upgrade.

Will you be posting a parts list of your upgraded parts compared to the standard kits or was it really only that wine barrel of a copper cap and the path resistors?

Post by: Hobbsmeerkat on 19 Oct 2021, 11:40 pm
Will you be posting a parts list of your upgraded parts compared to the standard kits or was it really only that wine barrel of a copper cap and the path resistors?

It was essentially as follows:
Foil inductor upgrade
600V KPCU01 Miflex cap & 0.1uF Miflex bypass
Path Audio resistors
Miflex 0.1uF cap bypassing the cap in the woofer circuit,
The only thing stock about them is the sonicap in the woofer circuit.

I didn't really do anything different with the crossover or cabinet other than making it so I can change the length of the wires and swap out the crossover.

If i were to do it again, i would go with the smaller 250V KPCU03 version thats roughly half the size & a single path resistor that is "close enough" rather than doubling up half values to get the exact value so I could still fit it inside the cabinet.
Oh an probably use paper backed veneer instead of RAW veneer.. lol

Nothing to be concerned about. The best way I can describe it is natural realism. A violin sounds like an actual violin in the room.

That's quite a statement!  I'd love to hear those speakers one day. 

Re: the ODAM cap - I switched from Miflex to ODAM caps in my BA3 amp because the Miflex melted because the amp is so damn hot.  The ODAM caps are very neutral, transparent and dynamic.  Very nice!  But they were also missing a bit of soul in the music, IMO.  So I bypassed them with copper foil Duelunds and the magic is back.

If you ever make your way thru, you're more than welcome to stop by and ill bring them to the shop

Good to know.
In the future I may build a 3rd pair of crossovers with the Vcap/Duelund/Path combo since I can easily swap them out.
(The 2nd pair of crossovers are cheap $25 crossovers using the cheapest parts I could find on Parts Express still need to finish assembling them)
And Maybe a 4th pair with the stock crossover parts.
But that's for the future, plus were still waiting on more tube connectors.. and I would need at least one set for each of them. :P

Yes the Duelunds add a texture you sort of feel. The musical “vibe” is palpable.

Something to be careful about when using paper backed veneer is that the veneer itself is very thin. Usually about 0.010" where the raw wood veneer is more like 0.045" thick. If you end up with a minor imperfection, you can likely sand it out of raw wood veneer but not on paper backed veneer. Each type of veneer has it pros and cons. Neither is perfect.

Congratulations Hobbs, you'll enjoy your maxed out NX-Studios for years.

Suggestion to Danny & Hobbs. This set with external crossovers is the perfect opportunity to demonstrate the effects of Good, Better, Best crossover parts. Hobbs has built the Best version. I expect know the basic kit parts are Good. Something in between as a Better level. I would love to see GR demo this at 2022 LSAF and/or Ron could do a video on New Record Day YouTube channel discussing the quality differences heard as parts get better and better.

I'd say there's a trade off.  In favor of the ODAM/Dueland combo (although I use copper foil instead of silver foil Duelund in my setup), there's absolutely a better view into the recording.  Acoustic space in particular is just incredible. 

On the other hand, the Miflex caps are less insanely resolving, but are much more beautiful and soulful.  Which I also love.  So, IMO, there's a tradeoff and whichever one you prefer is fine, as they are both great.

Thanks! That was my plan! and having heard them in a couple different places now I'm really happy with them.

I've already told Ron that he has my permission to borrow them at any time.

and I definitely plan to build out a couple different crossovers for them. Starting with the el cheap-o crossovers.
I do plan to build a pair of stock crossovers in the near future as well, though they will need 400 hours to sound their best.
And I'll probably do a VCap/Duelund combo as well sometime later.

NX-Otica comes first since they still have the base level crossover and the original BG Neo3 tweeter.
I'm Curious what he ends up doing with them.

Going off what I experienced with the fact that I did the same thing with my NX-Otica crossover that I did with my Studios, you are in for a treat.

What would a “better” crossover look like on the oticas? Something above and beyond the listed options?

I mean at this point most anything would be an upgrade. Since its got none of the upgrades currently except Mills resistors.  :P

But IMO, using Miflex copper caps and Path Audio resistors for the tweeter, bypassing the sonicap & cap bundle in the mids with a miflex bypass caps, as well as foil inductors for the mids and tweeter, would make them really something special.

As for the lower woofers? Maybe just the bypass the main cap, but it's low enough I think its likely fine as is with just a basic sonicap bypass.

Beyond that, it's hard to say.
