I do, nice.. where in MN?

I live in Albertville. North west of Minneapolis about 25 minutes.
As soon as it warms up, even a little, I will be able to get into the garage and get back to the weather-stalled XLS encore and servo sub project for my brother, and then SuperV for me, and a bottlehead amp.
Stupid MN weather.

Built these GR surounds for a friend a few years back, he wanted them painted the same color as his walls so they didn't stand out.
(http://www.audiocircle.com/image.php?id=28877)
I know this is cheating compared to really building but I wanted to try them anyway. PE curved sided gloss black enclosures.

Hi all Audio Circle members.
I have four (04) pairs of speakers all using GR Research drivers,
but even if I have plenty of pictures of them, I will not post them here.
I just want to avoid any unpleasant comments.
However, I am very happy with all my built and the sound of all of them.
Thanks Danny.

Neil,
Is that solid Cheery? WOW! Cheery is one of the most beautiful woods especially when left natural. Not sure if you tinted it slightly, but it's really spectacular! The craftsmanship, wood choice, and finish are all first class!!
Larry

Thanks! The sub is one of the AV123 sub drivers that I got from Danny for cheap and one of Danny's amps.The sealed version of the sub had a lot more output for movies but the ob version is more refined for music and suits me very well. I am not much for describing sound but I would call it very musical and it does not draw attention to itself. FYI,I listen to jazz, classical and pop.
django, I like your stuff, especially the OB sub. Are you happy with its performance, as compared with the sealed version? Both have the same driver and electronics?
-
Thanks Guys, I used General Finishes, Arm-R-Seal, sanding between each of the several coats, 5 or 6. I then wet sanded 1000, 1500, and 2000 grit, and polished with 3m's swirl remover and a coat of wax. Very labor intensive, but very happy with the end results.
Larry, all solid Cherry except for sides and back, I used 1/4 mdf core ply. No tint or stain, Cherry just takes on a richer, darker hue as it ages. It is my favorite wood to work with right now, just finished up a bathroom vanity that actually came out nicer than the speakers.
Thanks again for the compliments

Neil,
Did you spray or brush the Arm-R-Seal? Also, what wax do you use?
Larry-
-
I mostly use General Finishes on projects but I have not tried the Arm R Seal very much, looks like I need to experiment with it more.
-
Like a few others, it's sort of cheating when you buy the cabinets, but the veneering had proved to be too much for me... and AV123 cabinets were such deals!
(http://www.audiocircle.com/image.php?id=57074)

Neil,

I used Foam brushes, any car wax should work ok. I had some Meguires Carnauba laying around.

Really like the veneer. I have never heard the N3 in tower version. I am going to have to make some cabs one day just to hear them...
Here are mine
(http://www.audiocircle.com/image.php?id=41371)
-
Thanks. It is Lacewood. I got it from the Formwood sale section which has great deals from time to time. The towers have really strong bass, its surprising.
-
the line arrays look great
-
I mostly use General Finishes on projects but I have not tried the Arm R Seal very much, looks like I need to experiment with it more.
The General Finishes Seal-A-Seal and Arm-R-Seal is good stuff. Easy to apply with a lint-free disposable shop towel pad. One coat SAC & up to 3-4 coats ARS easy-peasy and it looks great.
Larry..If you use wax on top be careful with auto products as they often contain silicone oil (polysiloxanes). Once you get silicones on a finish it's r-e-a-l-l-y hard to repair or refinish the piece as silicones will prevent new finish coats wetting the surface. Removing silicones is also very difficult. If you want to wax use something like Johnsons Paste Wax. It's carnuba and polyethylene waxes, no silicones. If you need to remove it wipe a piece down with mineral spirits, prepare the surface & recoat.
FWIW.."Lemon Pledge" smells nice, but it's made with siloxanes..bad news on good wood or wood finishes.

I just bought a pair of v2's with a down payment, sorry im struggling. I cannot wait. Thank you Danny for working with me. Sorry Danny has the pics since I do not have them at home yet. I bought really because Danny is in Texas 4 hours from me. I supported llano and white audio labs for years, now I am supporting GR research. Plus im dying to try ob speakers. I hope they live up to expectations.

lmao based on your map yes.

underdawg you will love open baffle speakers, I have had OB's for 8 years now and there is no going back at all.

hope you right because this is my most expensive purchase in audio over 20 years of buying :green:

Guys,
Somehow I've missed this thread. I'm one of those builders who usually leaves speaker projects in raw wood. After I check out a design principle, they get scrapped or sold to friends. ( I have a lot to learn, and I learn best by doing.)
That said, WOW!!! You guys do very nice work. I hope more cool pics get put up. I really enjoy them. Makes me want to properly finish & keep something. This is a great thread.

This is the built-out version of the first cabinet photo on this thread. Thanks to Jon Parkhurst for building the cabinet with 1" Baltic birch construction, to Danny for the kit, and to the Skiing Ninja for putting it all together. Also thanks to me for requesting the 1" roundovers, the extra inputs, and the removable back board.

Check out the awesome dual "woofers"! :lol:
(http://www.audiocircle.com/image.php?id=84414)
(http://www.audiocircle.com/image.php?id=84413)
-
Bet you liked those removable backs!!! Why two sets of inputs?
-
The two sets of inputs are in parallel (not biwire) to allow for any type of wire termination to be used. The removable back was more of a benefit to the Skiing Ninja as he did all the assembly work. I'm debating leaving the back removable versus gluing it on.
-
Put a little silicone caulk in there so if you ever would have to get it off you can but it will still seal it tight. Looks great.
-
Thanks. And thanks for the amazing deal on the cabinets. I wasn't really in the market for these speakers but the price and quality of the cabinets was too good to pass up. Now I have them playing quietly all the time to speed up the breaking in process, especially of the platinum sonicaps. They sound great already, especially the soundstage and imaging, and I expect them to get even better.
-
Awesome , they look great.
Love the "dual woofers too" :lol:
-jay
-
Looks like the driver spacing was increased slightly. I wouldn't say that caused a "problem" but the vertical off axis response and driver blending my not be quite as smooth as it would have been otherwise.
Good call on the dual sets of binding posts. After you have some burn in time on them you might be able to switch between the two sets and give some feedback on the differences.

Agreed :thumb:
bibin3210,
The black paint looks really good. That can't be just spray cans?
What kind of paint did you use and did you use a compressor and paint gun?
-
Few Snaps of my recent XLS-Encore build:
Very nice! What veneer (source?) and finish did you use?
-
Thank you Scott, WireNut and Todd Willhoit for your comments.
@ WireNut: That is NC Metallic Black with less glitters applied using compressor and spray gun. After 72 hours of curing, hand rubbed and wax polished (Formula 1).
@Todd Willhoit : It is not veneer, self adhesive PVC laminate.
You can find more work in progress images here. (http://forum.diyaudiocart.com/discussion/4/gr-research-x-ls-encore-build/p2)

Anyone know how I could contact John Parkhurst? I can't yet see is profile nor send him a PM due to my noob'ness.
I am interested in his remarkable speaker building handywork.
thanks all,

These are being used full range with the Acoustat 1+1s for the bass from 30-60hz which was an easy integration. This setup is temporary until I pull the trigger on the 2 or 3-8" "speaker stands" Danny is working on or maybe a 2-12" in a similar type stand.
The NS3s are fully upgraded with all the add-ons Danny created for this speaker. With about 80 hours on them they sound pretty darn good but as I understand, they will get better until they are fully broken in.
BTW, They are way above ear level because I am using stands I used for other speakers connected to the Acoustats until I purchase others. Also, I have the third box completed too. I started with 3 just in case I screwed something up.

These pics are in my build thread as well but figured they could go in the "PE" as well

The matching bases is a great idea. The speakers and subs look like they are a system, and the bases give both cabinets a larger footprint for stability.

I will not call it marquetry. When I cut the miter angles on the rails to make the top, I endeded up with triangles as leftovers and didn't want to throw away and decided to do what you see with touches of oak to fill the voids. When I get home I will take a better picture for you.

Thank you for your comments. There was no way to hide the sub in my space and from the onset I wanted to give this sub the best look I could and make it presentable.

You are correct; the box itself is all MDF in satin black and the top, feet and front + the marquetry look is solid wood, this design made with leftovers.

F12G SERVO SUB
I read about the good and bad of various sub-woofer variations, including infinity baffles, but I kept coming to the sealed sub; accuracy attracted me more so than the sonic boom. I looked into Rythmic and its servo technology and the way Ryan and Danny explained how it works made sense to me, but because I was busy building surrounds and center channel from Danny’s kits, I was not ready to commit to anything. When all were completed and put to service, I had more time to evaluate my needs.
It took me a little while to make a decision because I was not sure whether I will need two subs and if that would have been the case; you all know that it is better to cut both at the same time. I did some reading and calculations and figured that one may be enough for what I was looking for, the area I have is 1700 cu/ft., open space. I became more familiar with the servo idea and was sold on the paper-based F12G from Danny. The main reason I went with the paper and not the aluminum is because I listen more to music than movies. I know, I know the new trend is the OB subs and as much as I like them I had to let them go for now; I do not have the real estate they required.
Talking about the build, I followed Danny’s recipe for his sandbox to the letter, except that I cut rabbets for the internal braces and enclosed the electronics in its own box because I used fiberglass and did not want any of it touching the back side of the amp. The inside also has No-Rez, one full sheet as suggested and all joints are sealed with silicone caulk.
As in my previous builds, there are no mechanical fasteners anywhere, but I used plenty of cookies mostly for alignment purposes. As far as the sand, make sure to tap the sides with a rubber mallet as you fill the cavities because this helps to compact the sand; if you do not tap it, you may think it is compacted, but will ended up with voids once you put the sub to service. I finished the sides with rattle can satin black. The top, front and feet is walnut with accents in oak and finished in satin medium dark walnut from Watco.
Setting it up took many trials, issues with time/phase alignment mostly; relying on my old ears and no instruments like a SPL meter is a bit frustrating, but once I figured out how to tune it, it was best to leave phase at zero and play around with delay distance from the ProPro until I managed to sync the sub with the fronts the best I could. I am still playing with the other controls and getting familiar with what they do, but for now the sub is set at 80Hz crossover from my PrePro and recommended settings in the sub end, it sounds very good. I am running XLR cable to the sub simply because the cable is going over the ceiling and down for a run of about 30-ft.
I have subjected the sub to different content, from movies to music of all sorts and I am impressed with its performance and the way it projects the sound. I may add that I did not have much of a problem about location, it is sitting along the longest wall and from my sitting position all the bass seems to emanate from the main and center speakers. The more I listen to my favorite songs, the more I like the sub, new bass content pops here and there, at times it seems like I am playing a different song; I can also feel it and when that happens I know the sub is going subsonic….awesome!! The SPL generated from this one sub gently rattles my house with authority and sufficient thump without displacing my china or glassware, and there are so far no complaints from neighbors at all and the volume is at 50%!! I bet if I cover or disguise the sub, friends will be wondering how my smaller speakers are able to reproduce sounds that low (I have not had friends over yet.)
Here are some pictures of the finished sub; sorry, I did not documented the build since it is basically a copy of the sand box Danny provided, but dressed differently as mentioned above.
Thank you Danny for your guidance, patience and for providing the plans for the box. I am really happy with the sound from this sub, it really complemented the overall sound without being intrusive with colorations or the so called sonic boom.

Hi bocina,
nice looking all around, very nice looking top,

This message is for Jparkhur. I am not responding to this particular conversation, but am trying to contact you because you sold someone an ATI AT1506 amp at one time and mentioned that you had e-mailed a copy of the AT1506 to the buyer. We have an AT1506 also, and are having some trouble with it, but have no manual to use to trouble shoot it. If you still have a copy of the manual, and would be willing, would you please e-mail it to me at ghspurlock1@nc.rr.com?
Thanks very much for your help.

The original Wedgie, I love this speaker:

(https://www.audiocircle.com/image.php?id=141734)
The bass section ultimately didn’t work for me, I believe I built it too small and the output of the drivers had a negative impact on each other. I am currently (not actively :duh:) revisiting this speaker with a different bass solution.
NX Otica MTM with Stereo H Frame Servo Bass (my Current speaker):
This is a great speaker, easily fills my largish space, excellent imaging and beautiful tone. I learned a lot about finishing on this build thanks to this community.

Looking through this thread I see we need some of the new NX-Studio Monitors. Just built these for my dad. (March 2020 Right as the world was catching the flu.)
These are Danny's newest design at the time of this posting. They are a hybrid design with an open baffle tweeter and a sealed box lower section. Designed to be able to be placed close to the wall but work great well out in the room as well. And as the name implies they are great for monitoring as well. I can hear the subtlest if details. Great tone and incredibly smooth sounding.
This is one impressive sounding speaker! Truly world class high end audio! Many thanks to Danny for your contributions to the audio world! :thumb:

Yes those are some sharp looking speakers.

Thanks guys! But he did pay for them, I provided the research and construction. I'm sure he will love them if and when it is safe for me to deliver and set them up for him. It was a fun project and I am enjoying my unexpected extra time with them.
-
Sonicjoy,
Have you thought about building speakers as a way to make a few $$ during this time of whatever?
-
Funny you should ask because I have. However getting materials is proving to be a problem now. Danny is having trouble getting stuff as well. The outfit I get my wood and MDF from is now closed until further notice and I live on an island so running to Home Depot is problematic as well.
Good thought though.

The X-Omni is the surround for the X-Statik, not the A/V-O. The X-Omni does exist. It’s the save as the A/V-O but uses the same drivers as the X-Statik and X-Voce

I appreciate the info, but I'll be using the A/V-O because I already have them built and working. More of a repurposing than anything. The X-Statics replaced them as the L/R
Edit: They do get pulled out into the room when I'm listening to music. For everyday TV though they stay back and out of the way.

Hey guys, just wanted to share a project update real quick. I've posted some images and questions elsewhere in this forum, but will summarize here. Three to four months ago I had never even considered building a speaker and now my first project is nearly complete. There are some spectacular build threads on this site of large complex designs, but my system is a little simpler. Hopefully some of the other beginners out there will be encouraged.
Veneer is rift sawn white oak with one coat Weatherwood Reclamation reactive stain (two coats on sub) plus one coat of Waterlox sealer and six coats Waterlox satin finish. Its a copy of the finish described by Peter Rawlings on his youtube channel, but mine came out much darker due to the veneer type.
System is very budget oriented - Onkyo integrated and CD player, Arylic streamer, Rega TT. I selected the base XLS x-over, no-no res, base level terminals. I have some plans for improvements, but am really enjoying them as-built. I'm not getting much performance out of the sub just yet - hope to make some improvements there soon...

Finally finished my XLS project. Veneer is rift sawn white oak with one coat of Weatherwood Reclamation, one coat of Waterlox sealer and six coats Waterlox satin finish. I followed the same process as Peter on one of his youtube videos, but got a very different result. Rift sawn oak seems to be much more reactive with this type of stain. They turned out way darker than I wanted, but I like them anyway. sorry i dont know how to rotate the image

I like 'em. It's been a while since I've seen the pair I did on YouTube, but I think I like yours better. I've found there's an element of unpredictability when using the reactive stains. Kinda the nature of the beast, I suppose. Anyway, Kudos on your project!
-
I'm enjoying the dark color as well even though it was kind of an accident. I emailed Weatherwood and they suggest one of their finish products called White Oil. It will bring out more of the grey tones in the reactive stain. I may try that on my next project.

You might get better bass from the subwoofer if you move it toward the corner a bit more.

Kind of reminds me of the music instrument world where they beat up a guitar or bass to make it look really old, they refer to it as a relic finish. I wonder how you could distress or relic speakers? Maybe make some rings on the top where the wife put a plant and damaged the finish, push in the dome tweeter from the toddler, or recreate when the cat used the speaker cover as a scratching post. :x

Very nice!
How did you achieve those big round overs when the wood was just 3/32".
What adhesive did you use to lay up the veneer?
Thanks.

My first DIY "audiophile" speaker project. I had, as a kid, made some speaker boxes for our cars but nothing like the cabinets I built for my X-LS Encore speakers.
I got the speaker Kit from GR-Research and sourced the wood locally for the cabinets.
Construction is birch plywood (Not a fan of working with MDF) with quarter sawn Cherry veneer. My first attempt at using veneer. Thank to Peter's YouTube video on the subject it went without issue. Finished with Rubio Monocoat (Finishing on ez-mode!)
Just need to let the finish cure then I can install the crossovers and the speakers.. Can't wait!

Hello fellow GR fans, first post here. Been messing with speaker since I was 8. This however is my first GR kit.
Asked for the desktop mini kit for Christmas from the wife and started shortly after.

Next steps will be a nice coat is shellac to a satin finish and final assembly. It’s taken me longer than I wanted but I’m a perfectionist so I’ve stopped quite a few times to correct things or redo them. I am thrilled with the look so far.

Those fabric sides are very cool - I wonder why no one every thought of that before.

Those fabric sides are very cool
+1 and I like the darker wood color as well

I had put some text in the comment section on rack pic but seems it did t make it onto the post.
The cabinets are veneered in walnut, coated with danish oil in dark walnut. The speaker grills are magnetic and I saw somewhere in the past were someone else had placed magnets on the sides of theirs so the grills can store there if wanted.
Thanks for all the positive comments.

Got my Desktop Mini speakers finished. Overall I’m happy with the finish.
(https://www.audiocircle.com/image.php?id=237875)
Really wanted a mat to satin finish but my finishing skills weren’t up to the task. So out came the 3000, 5000 grit sandpaper and polisher used on the car.
(https://www.audiocircle.com/image.php?id=237876)
Think I’m going to redo this speaker grill cloth. I can get it to fit cleaner and better corners.

XSLS cabinets waiting for the goodies.
Long time reader, first time poster. Also first speaker build.
Sorry I don't have many build pics, but I added what I had. I live in a tiny city apartment, built everything in the garage on my smallish workbench and all of the clamps I had. The first 'complete' photo are the speakers unfinished. the boxes are wrapped in Curly Maple Veneer with two coats Pure Rubio Monocoat. Its pretty amazing how the Rubio makes the Maple pop while not adding too much color. I tried like 10 different finishing options on little sample boards, so pumped how they came out.
Fully lined with no-rez and the bottom chambers are filled with sand....these things are super heavy.
I'm currently using the cases to support my Kplisch rp600s which were in sore need of an upgrade.

Very very nice. So you used a single sheet of veneer wrapped around those rounded edges?
What adhesive did you use? Are the backs veneered as well.
-
Thanks!
They are both wrapped from a single 4x8 sheet. The backs are Veneered also. I used this glue called heatlock(you can get it from veneering supplies.com You apply it to both surfaces with a roller then iron it together.
I used a 1/2in round over bit on the front so that the 'front' three sides are a single sheet of veneer. kinda gives it a more natural look and removes the most visible seam.
Cheers!

I might as well add my two builds. The first set is a pair of XLS Classics built for my daughter. The stands were made out of MDF and have a hidden channel for speaker wire. The stands are filled with sand for weight and to ensure they are vibration free. I used Duratex on both the speaker and stands since it is very easy to apply and very durable. They sound excellent.

The next set are XLS Encores with all upgraded parts in the crossover. These are conventional 3/4" MDF boxes covered in self cut 3/16" Tigerwood veneer. They have a 1/2" roundover on all edges. The Kanto stands are also filled with sand to add weight and ensure they do not vibrate. These were made for my lovely wife and sound fantastic!

NX-STUDIO speakers completed last Spring and sounding better every day.
The NX-Studios were assembled from Jay's flatpack using the techniques that Peter so painstakingly layed out in his videos. Hickory veneer was applied to all exterior surfaces. The finish is hand rubbed shellac, 7 coats of a very light cut. All interior surfaces have No-Rez applied, with or without the foam layer, as appropriate. Polyfil was placed in the woofer cavity before buttoning up the enclosures.
My system:
Conrad-Johnson PV-12 preamp
Conrad-Johnson Premier 11A amp
VPI Scout II with Grado Statement Sonata II cartridge
2 - Rythmik F-12G subwoofers (GR Research paper cone driver and 370PEQ amp)

What method did you use to trim the veneer around the wave guide? I love the look of the 1 piece veneer wrapped aren’t the front, I assumed it would get tricky around the wave guide. Great job on the build they look awesome!!

Thanks Kelly.
Great question! Before I started assembly - the one thing I knew was that I wanted one piece of veneer to span the sides and front. I also knew that opening up the tweeter holes was going to be the hardest part of this project. Wish I had an amazing secret to share on how to do that. Truth is it was a painstaking process and took a good bit of time.
NOTE: You need to know exactly where the opening is. I made precision templates of each of the front baffles BEFORE i began speaker assembly. I didn't assume that both baffles were identical. At that time I really had no idea how I was going to cut the tweeter opening but I knew it couldn't be done without a template of some sort. The front baffle needs to have registration marks that will be preserved until you are ready to cut out the tweeter opening. Tricky but can be done.
I started with a small router with a trim bit set just a couple of millimeters below the veneer. i made a template to remove about 90% of opening with that setup. I then switched to a Proxxon Rotary Tool - a Dremel-like precision rotary tool the size of a fat pencil. With the opening taped off I trimmed out all but the last few millimeters of veneer. At this point it is all hand-work with sandpaper wrapped around various shaped dowels.
Having steady hands (which I don't) will help. I guess the key to success is TAKE YOUR TIME. You really only get one chance to do this correctly. I spent a few weeks making the openings on both speakers. My technique was: work for a short time then walk away until tomorrow. I second you feel yourself getting anxious - STOP.
So there it is. Good luck!

Gr-research desktop mini speaker build
(https://www.audiocircle.com/image.php?id=250131)
Thanks to modern day CNC the seams in the flat pack were so small that just rolling on a thick primer coat was enough to hide them. I decided I liked the white color so I left it.
(https://www.audiocircle.com/image.php?id=250132)
BTW:
Danny mentioned designing a LGK tower speaker but I haven't seen them offered yet.
-
Were still developing the LGK 2.4 towers. We got the 2nd test tower just last week. We'll be testing it out soon.
-
Here is my build of XLS Encores.
After watching Ron (NRD) talk about Mike's incredibly beautiful build and how good they sound and then seeing the component choices and watching Danny's upgrade videos, I ordered a kit at the end of 2020.
I was convinced that these are superb parts and sound quality that should beat the rest.
Bought a Sealed Sub Servo kit with PEQ370 as well, so I would get a really good 2 channel system.
(https://www.audiocircle.com/image.php?id=251647)
Danny's XLS drawings are easy to follow, but I didn't wanted a square speaker. I wanted something with curved sides, like ATC. Since I don't know how to calculate volume on a curved speaker, I had to take the simple method. Paper tape measure!
I knew what the dimensions of the front baffle should be and the placement of the speakers. Also I knew the inside measurements from Danny's original drawing.
Found ATC's original dimension drawing. Manufacturer a long arm for my router. Made some tests and got a nice curve that fits as a template.
Made templates from thin mdf for the Encores and Sub.
(https://www.audiocircle.com/image.php?id=250105)
Then IKEA's paper measuring tape comes out. Put it on my templates and get the inner volume, horizontally for the speakers. Cut the template and everything is ready for cutting . Routing.
Also made a brace for the Encore, which made me add 12mm (1/2 inch) to the height.
(https://www.audiocircle.com/image.php?id=250104)
I had to kerf the sides on the inside, so I could bend them. Lots of wood glue in the kerfs/slots.
In the build I added a small space/cavity in the back of the cabinet, 12 mm (1/2 inch) which I then filled with clean sea sand (500 ml/16 Oz) when the speakers were done. To dampen some of the cabinet's resonance, in case of.
Maybe overkill for a small bookshelf speaker, but I did it anyway.
(https://www.audiocircle.com/image.php?id=250106)
(https://www.audiocircle.com/image.php?id=250107)
Under the motherboard and on the brace, I used something like Dynamat. The rest of the cabinet got NoRez. Fiberglass behind the woofer.
(https://www.audiocircle.com/image.php?id=250109)
(https://www.audiocircle.com/image.php?id=250108)
The subwoofer was filled with NoRez and a sheet of fiberglass.
Both cabinets feels like a stiff box when doing the knock test. Solid.
The Encores weighs 10 kilos/22 lb.
The Sealed Sub weighs 45 kilos/99 lb.
They do sound great and they are playing at least 5 hours a day at low volume and when I turn up the volume (wifeys away) then they really sing beautiful. No Regrets.

New at posting here, so if it ends up in the wrong spot, sorry in advance. These are my version of the X-LS Encores. I purchased these at GR Research last September while visiting friends in Texas. It was great to meet Danny and Hobbs. I was there early in the morning and they graciously fixed me up. It is the basic kit built with a flat pack and binding posts from Parts express. I used NO REZ in this build and rounded the tops of the front baffle. The paint/coating is automotive paintable gravel guard. My thoughts were that the gravel guard would help suppress resonances. Pretty happy with the build.

he build.
Why does it look taller than a typical Encore? Like there's an inch extra space below the woofer.
-
Yup they are. I built them using the cabinets from Parts Express. I kept the placement of drives consistent with Danny's plans. These cabinets are 0.06 cubic feet larger. The cabinet width is the same as the Danny's plans.
The Denovo cabinets are 8 1/2 x 16 x 11 while Danny's cabinets are 8 1/2 x 13 1/2 x 12.
My thoughts were that 0.06 cubic foot difference would not cause any major change. So far I'm very satisfied.

Beautiful veneer job! It looks like you were able to complete without bearing marks, did you sand them out or do do have a process that keeps them from developing? I have veneered several speakers and the bearing marks are my arch nemesis. Again wonderful veneer job and speaker build!
Thank you, Kelly

Thank you, Kelly
I used an acid brush to fill the marks with water and after three or four applications the veneer swelled to original level. I didn’t scrape or sand until the last pass of water had dried for a few days, and I didn’t sand in between. I’m referring to red pads for sanding here, not paper, and gray pads for applying the polyacrylic (polyurethane made the test sample too dark.)

This gives me some motivation to get my Studio's started.

In my case it’s Fat Dots from Herbie's isolationing the speaker from the stand.

+1 Herbie's are what I use under my speakers also.
-
I also used Herbies between the stand and speakers. The stands are sand filled with custom built Home Depot vibration isolation levelers. I used pressure activated cherry veneer which turned out very nice. Kudo’s to Danny and his team - these totally disappear with well recorded music. I love watching friends mouths hang open when they hear them.
