Title: Corona Virus update (See latest update).
Post by: Danny Richie on 1 Apr 2020, 02:49 pm
Hey guys. I wanted to give everyone another update.

We are still open and going full blast. And we are covered up with orders. Understandably everyone is shut in and wanting to work on their audio projects.

We really appreciate the orders.

However, it is effecting our suppliers. We have had more No Rez on order for about 6 weeks now. And that company is located in NY where almost everything is shut down. A delay in getting more plus going through it faster than ever means we are now out of stock on it.

Ohio is also shut down to essentials only. So I have not been able to get in more inductors from Erse. And I am now out of quite a few values need for some of our kits and recent upgrades that we've done.

I will make note on our website the outages shortly.

Please be patient with us and we will resume shipping all that we can as fast as we can get in some of the materials that we need.

Thanks for the update Danny. This whole mess is getting very frustrating! It's getting harder and harder to do many things. Including relaxing and enjoying music. Just can't seem to get all this off my mind long enough to relax. May have to take up drinking as a new hobby. Drinking and music do work well together. Humm

Good luck and stay safe everyone.

I totally understand. It's affecting my business as well. One of our vendors that provides shelf-stable meals for our seniors is having trouble getting product in. This has me keeping a close eye on the nutritional content of what they can provide. As for building speakers, I can no longer go into the store to pick out hardwood so I'm limited to what I have on hand. MDF is going to be an issue if HD stops letting people come ito the store also. I stocked up on enough MDF for current orders and can still get veneer shipped in though my main supplier is limited to stock on hand.

New update.

We got in some of the inductors that we have had on order. So we have started shipping some of the X-LS Encore orders that have poured in this last week.

But we did not get all of our inductor order, and we are still out of some of the values needed for the Klipsch RP-600M, RP-600C, and RP-8000 upgrade kits. We have a LOT of those ready to go when the inductors arrive. Those kits and the Forte 3 upgrade kits are also waiting sheets of No Rez.

If all goes well we are hoping that a YRC freight truck shows up tomorrow with another 300 sheets of No Rez. And then we can get out some back ordered No Rez orders.

I really hate having orders in house that I can't get out right away.

Guys, please hand in there and please be patient with us. We have never had this many orders all come in at once. We are filling them as fast as we can.

Glad orders are up and y'all are keeping busy, even if shortages are impacting shipping.

Jay, any updates on the Studio flat packs? (Tho i imagine you're busy filling other orders, at the moment.)

Danny, are there any shortages on crossover or driver parts for the studios?

I'm not in any rush cuz I know y'all are busy, just curious on their status, and if i should go ahead and get in line, or wait for the time being.

Really  busy but   trying to get to it

Update!

Long awaited inductors showed up today.

This will allow me to fill about 40 to 50 orders that are in house waiting for those inductors.

Many are X-LS Encore orders, and Klipsch upgrade kits on about three different Klipsch models. There are also quite a few Elac upgrade kits going out in that group too.

We will try to fill these in the order that they came in. Please be patient. I have people in here helping me but we can only get them boxed and out so fast.

And just when I got caught up on X-Statik and X-Voce orders, quite a few more just came in.

I have not been answering emails until after UPS picks up outgoing. I have been getting 80 to 90 a day that need answering. I was up last night (on a Sunday) answering them until 12:15 at night. So if I don't get to you email right away please hang in there. I'll get to it.

And thanks for all the orders.
Title: Re: Corona Virus update
Post by: Danny Richie on 6 May 2020, 03:16 pm
Things are still moving at 100 miles an hour over here.

And we are still in a bind waiting for supplies to get here. We blew through the 3.0mH inductors used in the X-LS Encore's and are waiting for more to arrive. We also blew through 12uF caps in the Erse Pulse X poly caps and in Sonicaps. We are in wait mode to get those as well. All of those things are holding up many X-LS Encore orders, and an A/V-O order.

And the shortage on the caps are also holding up X-Statik kit orders that are getting Sonicap upgrades.

On a good note our 16 ohm servo subs are on the water and headed this way.

So please hang in there with us. We are filling orders fast, but can't fill some of them until we have what we need.

I know this virus deal has many of you stuck at home and you want to work on speaker projects. Thank you! But it has also crushed our supply lines for some products. So please be patient.

Title: Re: Corona Virus update
Post by: Danny Richie on 13 May 2020, 04:06 pm
Update:

We are still waiting on caps from Erse, and now Solen for our base level models. We have been eating up the 12uF cap values.

Both of those orders should be here before the end of this week.

I am also still waiting for the 12uF Sonicaps to arrive at Sonic Craft also. They will ship to them this week. So the first of next week I will have them to fill those orders.

I just got in 300 sheets of No Rez less than 3 weeks ago. I bet we are down to 60 sheets. I ordered another 300 sheets on Monday only to find out that they are having trouble getting raw materials and they are going to shut down for two weeks. They say they won't be able to ship my order until after June 1. I tried to sweeten the order and offered to bump the order to 1,000 sheets if they could get them done before they shut down, but they said they could not fill the order no matter what. So I bet I will be out of No Rez in another two weeks or so. So please order only what you need if you need it right now.

Also, more tube connectors have been ordered as of the first of the year. The new ones are coming from India and are to be a higher purity Copper and the male ends will also be high purity Copper. But the virus has delayed things there as well. Factories in India have been shut down too. It looks like 3 more weeks before we can get them. And they have made thousands of them. It was a 10,000 piece order. We currently are out, and all of them that are in here right now are allocated for orders that are already in house. So we will go two to three more weeks at least without being able to fill tube connector orders.

Ugh!

We are ordering 4 to 5 times our normal quantities of everything to keep stock and keep up with demand, but manufacturers can not make and ship fast enough. So you guys are just going to have to hang in there with me until the country gets back on more normal schedules, working, and producing.

Something else to note. If you order online your card or Paypal is charged as you order. I can't change that. And then you guys will have to wait until I can complete the orders for them to ship. 

If you call me and place an order using your credit card, then your card is not charged until the order is ready to ship out.

Emails have slowed slightly now. I am having to answer only 70 to 80 a day so far this week. So I am still spending 4 to 5 hours a day answering emails. So guys please limit your messages to specific questions or orders. As much as I love reading about how you got started in audio, I can't do that 70 to 80 times a day.

I'd love to hire some people right now and that is on the agenda, but we have to get through this whole virus deal first. Right now we can't be shut down. Our 6,000 square foot facility is 150 feet from our house out in the country here in Texas. So whether we are in our home or our shop we are still at home. Employees coming here to work right now will fall under some restrictions. So for now it is just my wife and I full blast. My daughter and son and law dropped by last week and helped a lot too (thank you!). We are doing all that we can.

So please bare with us. Once we get stock of all that we need then we can take orders in and ship them out very timely.

Looks like Parts Express is selling their own branded version of the Neo 3 tweeters, versions of the Neo 8 and Neo 10 will be available. Pricing looks really good, not sure where they are sourcing them or how they will measure.

Oh! Thats pretty interesting..
Here's a link for those interested: https://www.parts-express.com/grs-pt2522-4-3-1-2-planar-tweeter-4-ohm--272-122

That's actually pretty cheap, and about $80 cheaper than the official BG neo 3 tweeter.
I suspect that they're the same as the Chinese clones that have been popping up lately.

But for the price, I might pick one up just to do some testing on my own for comparing it against my own BG Neo3..

Post by: Hobbsmeerkat on 17 Sep 2020, 02:08 am
Update: I ordered one along with some accessories to make testing a little easier for myself. Not expecting much, but for ~$35 is worth a shot.

Looking at the pictures, it also seems to use bolts and nuts instead of rivets. Ill post further updates on it in my Neo3 back cup thread sometime next week: https://www.audiocircle.com/index.php?topic=171314.0

It also appears to have a dampening material in the outer slots, which is something that Danny Richie recommends, to get the highs to have wider dispersion.

I am tempted!

Im only buying one cuz its introduction price is like 60% off and i have a BG Neo3 (non PDR) I can directly compare it to, which ill be installing some yarn into for a direct comparison.

But expect plenty of pictures, & hopefully some graphs once I have them on hand.

EDIT:
Reading the full description, it is a full Neo 3 PDR replacement driver, it only has 6 magnets instead of the original 10 magnet models)
Even so i can still use it for back-cup/waveguide testing.
Looking at the Neo8 replacement, it is also a PDR model with 18 magnets instead of 30.

The mechanical drawings look exactly the same as the ones I got from the company in China that made me samples.

The problem that I had with the Neo 10 samples was that they used no damper on the diaphragm. So there were little resonance traces all over the place. And getting them to understand how to fix it was almost impossible. So there is some ringing in them all over the place.

Also, all of the pictures, measurements and graphs weren't of their own products. They were all pictures of BG products.

No surprise there, i guess. lol

But you mentioned that they didn't add a damper to the Neo10 sample, that makes me think thats what they did here as well with the Neo8 replacement:

(https://www.audiocircle.com/image.php?id=214710&size=large)

The pictures also show the felt being added to the outer back rows but not the front also?? :scratch:

(https://www.audiocircle.com/image.php?id=214711&size=large)

So I'm guessing that the Neo10 replacement has the same issues that the above Neo8 PDR replacement does?
Title: Re: Corona Virus update (See latest update).
Post by: Danny Richie on 17 Sep 2020, 07:39 pm
Yes, you can see the yellow film of the diaphragm with no damper. Those babies will ring.

The BG units used a thin black damper on the diaphragm. Mine uses a thin white damper.

Danny, the Neo8 style copy is significantly narrower than real Neo8 drivers from BG which is odd.  And PE's listed freq. response is unusual to say the least.  The spec sheet makes no mention of the measurement conditions, but it's certainly NOT free air dipole given low end response.

You're right, they're quite different.
NEO 8 VS GRS
(https://www.audiocircle.com/image.php?id=214717)(https://www.audiocircle.com/image.php?id=214710)

It also classifies itself as a "slim" tweeter so im guessing that there will be a more "stanard" model in the future. But if its going to be a ringing mess, probably best to avoid them until a DIY solution is made.

Nah, while it is slightly skewed, the main difference is in the width from the outer holes to the lip where it drops off to the area with the terminals/rivets, it looks as tho about its been made about an inch narrower than the one on the right.. (24mm according to the schematics below)

(Lets just use this post instead of posting a 3rd in a row)

Looks like the page for the GRS Neo-8 replacement just dropped:
https://www.parts-express.com/grs-pt6825-8-8-planar-mid-tweeter-8-ohm--272-126

(https://www.audiocircle.com/image.php?id=214722)
(https://www.audiocircle.com/image.php?id=214723&size=large)


$50 introductory price, and seems to have the proper buffer layer that the "slim" model doesn't.
Tho I'm more curious about the upcoming "Neo10" model, & may pick up a pair if they aren't overly expensive. Just to do my own testing, so long as it has the proper damper layers
It also has the full 30 magnets, & does not use PDR layout.

Looks like the rest of the Neo series is available. Will be interesting to see how they measure compared to the original BG drivers. The page HTML code showed place holders for 5 models.

Youre right, it must have dropped someone last night.

Here's the GRS Neo 10 replacement:

(https://www.audiocircle.com/image.php?id=214758)
(https://www.audiocircle.com/image.php?id=214759&size=large)

My only confusion with this model is that it says it uses "42" magnets?? That's 21 per side... But looking at the info for fhe BG Neo10, it shows as tho it should have 72 magnets at 36 per side...

Title: Re: Corona Virus update (See latest update).
Post by: Hobbsmeerkat on 18 Sep 2020, 02:53 pm
Looking at the two response graphs, i believe the GRS 10 has been tested in a traditional cabinet. In the paperwork for the Neo10 it says the response is boosted in the 300-1K range when used in a box, which is what the GRS graph shows. The Neo10 has been likely been tested in a OB setup.

I was hoping they'd come in closer to the $100 range, but even at $130 they're still ~55% cheaper than the Neo10.

Another odd thing is that the GRS 10" planar shows an 8 ohm impedance in the PE add, but the datasheet shows 4 ohms.  The BG NEO10 is 8 ohms, so that would change the passive XO design, if the datasheet is correct.

Nah they're both 8-Ohm loads according the the PE pages, and the PDF sheets, but there are some other minor differences.

(https://www.audiocircle.com/image.php?id=214767&size=large)

look at the differences in how their sensitivity is measured tho..
BG following the industry standard, and GRS doing whatever i guess.. :lol:

The first GRS 10" planar datasheet I downloaded says 4 ohms, they just changed the datasheet recently to 8 ohms.

Interesting.

That's really weird. Cuz the PDF does say 4ohm but the impedence graph clearly shows a 6.8ohm load??

2.83v is definitely an industry standard.

I actually had to do a little digging but you are correct. 1W is the same, 2.83v^2/8ohm= 1W its the same measurement, but stated in a different way.

I watched a tear down video of the Neo10 and while I assumed that it had 9 magnets per section, its actually 7, and unlike the Neo3/8 they are longer. This means there is only 3 rows of them, not 4.
Meaning the 42 count it most likely correct, with 21 per side, like the GRS-10" page states.

Makes me curious if a pair of "Pseudo Minis" could be built...  :lol:
A pair of GRS-3s & GRS-10s would cost about $320...
I believe Jay still has some Super Mini flatpacks going for $250+ shipping.
Then depending on the cost of a crossover, I'm guessing you could build a pair for $800-ish or go with more "budget" options to keep with the "Pseudo" theme, based on Danny's schematics for maybe $700?
Only snag would be the GRS-3 using the weaker 6 magnet PDR design instead of the original 10-magnet model, it might require a redesign of the X-over?

I think it would be a "fun" build, but I wouldn't be able to enjoy them, esp since I already have my XLS built & the NX-Studios still in progress, and don't have the space to enjoy them properly.

One issue is that the crossover would have to be redesigned. Since those drivers perform differently than the ones the crossover was designed for, it won’t work with those drivers
Title: Re: Corona Virus update (See latest update).
Post by: Hobbsmeerkat on 19 Sep 2020, 07:31 pm
Yeah, I figured it probably would likely need a new crossover.
But for the price, I almost wouldn't be against building a set and have Danny design the crossover. But spending $800 just ain't in the budget right now, unless someone wanted me to build it, send one to Danny for the new crossover, assemble the crossover, and ship it to them.
By then we're looking at close to $1000+ after shipping & a small fee for time/assembly..

But that's only if someone is willing to take the risk building a kit with them to see how they perform..

I would be interested if Danny could give his blessing with this new Neo10, but from what he is saying, I assume they look almost the same than what he had in hand, and then moved on to another potential solution.

But let the designer tell us what he thinks.

The ones that I received weren't usable. With the undamped diaphragm there was just too much ringing.

Yeah, I'm still on the fence about picking one up just for testing purposes. Cuz only the slimmer 8" model lacks the damping fabric, all the other pictures show a similar black damping layer to the standard BG products with the only visible differences being nuts/bolts instead of rivets.
But I'll make my decision after I do the testing with the GRS-3" PDR clone.

If I knew where to source that damper fabric, I'd try applying it myself, since its glued to the magnets/frame, but its probably not a realistic thing since it would risk damaging the diagram.
It looks like a ultra-thin felt material, about as thick and transparent as tracing paper, but more open and fibrous/soft than an actual paper.

If you take one of those things apart you'll never get them back together. They blow themselves apart as soon as you unscrew them.

Post by: Hobbsmeerkat on 21 Sep 2020, 02:18 pm
A fair point, tbh.
Watching a Neo 10 tear down they had to use spacers as it was disassembled so it didn't shift or fly apart.
I do need to watch the neo3 tear down.

On that note, my GRS-3 should be here today so I'll start a thread with some pics comparing it against my Neo 3 (non-PDR).

Here are pictures of the new GRS PT2522-4 planar tweeter that came today:

(https://www.audiocircle.com/image.php?id=214935)

(https://www.audiocircle.com/image.php?id=214936)

Look very similar to the BG NEO3-PDR style tweeter.  Definitely says made in China on the package.

Should be interesting to compare to the original BG NEO3 and the GR NEO3 in the Super Mini baffles.  I purchased the Super Mini passive XO kit's from Danny today to test with my test baffles that has his GR NEO3's installed.  My original pair of baffles have BG NEO3-PDR tweeters installed.

There is no guarantee that they will work like the original BG's.  This is all for trials.

Just got mine as well!
Here's a side by side with my standard Neo 3:

I'm gunna be writing up a thread breaking down the physical differences, shortly.
Feel free to throw in your measurements and thoughts on there as well.

Will do.

Interesting, is your BG NEO3 a NEO3-PDR version?  Does not look like it has the felt on the planar for damping.

My neo3 is not a PDR, its the standard 10-magnet model, more similar to Danny's current Neo3s.
But i did get some yarn from Danny to add to it during my testing.

The latest samples arrived and were tested last week. I did approve them. So they now about to knock out the production run. I will have more in stock late Nov. or early Dec.

Out of curiosity, how many of you are waiting for the studio monitors? It sounds like Danny keeps receiving orders for kits and some of us may be late in the game that we may need to wait after the first batch in December to get our kits :/

Hmm it seems no one is ordering anything and once the new drivers come in, I will be the only one to get my kit!!  :thumb:

I'm mostly waiting on the new batch of NQ drivers, so i can go ahead & order what I need from Danny, so i can then order some of my own crossover upgrades, namely Erse foil inductors & Path Audio resistors.

But I still need to decide on using either all copper caps, or just Sonicaps with copper bypass caps.. :scratch:
Tho as big as some of those copper caps are, I may just go with Sonicaps to save some airspace..

If you want to put the crossover inside, go with Sonicaps and bypass caps. The copper caps are huge. If an external crossover is OK, then the copper caps will work.

Yeah thats kinda where I was leaning, cuz I don't really have the space for external crossovers.

Sure you do. You're resourceful -- build external crossovers. Do you want the best sound or not? If so, don't entertain a lesser option.

I mean sure, but I have a few reasons against it.. Desk space for one,  since that's going to be their primary position, and I run a 3 monitor setup. Including one that takes up just around half of a desk by itself, and another one behind.

(https://www.audiocircle.com/image.php?id=214353&size=large)

Most any other option, like a separate box will add height, and they're already quite tall..
Then there's also the cost issue.. they aren't cheap.. at most I'd realistically go with all copper caps on the tweeter circuit, and the Sonicaps for the woofer circuit, to save on the airspace.

If I were building a pair of the Otica MTMs or any of Danny's other NX/Serenity kits, I'd be far more inclined to go all the way with them.

But I just wanted a desk speaker that I could grow into as I eventually upgrade my front-end beyond my Sprout100, which as it stands with my XLS & Rythmik sub, is already leagues better than any set up I've ever heard.. (outside of Danny's NX-Tremes, of course.) :P

I doubt that no matter what I end up doing, I will still be more than happy with their performance for a long time to come.  :thumb:

I have not been taking "orders" as in I have not been accepting payments for anything.

I have been taking order commitments (send me all of your contact information and what you are waiting), printing them off, and adding them to the pile on a clip board.

When drivers are close to being here I will send out email updates and keep everyone up to date on availability.

When all is here then I will take the orders and fill them.

What brand are these copper caps - are they the Audyn True Copper Cap, or something else?

They are the Miflex copper caps that Danny offers as an optional upgrade over the standard sonicap bypass caps.

We typically go with a .1uF value for most applications.

Post by: NeilBlanchard on 27 Nov 2020, 03:34 am
Thanks, that's what I thought. I am learning about this, and I see 0.1uF on many bypass caps, but on some smaller value "main" caps, the bypass is lower than that.
