You're going to try and poison someone with it for life insurance?

You're going to reverse engineer it?

I suspect the way to get a diaphragm is from TAD but that they would only repair one from one of their speakers. I recall casually asking about getting the drivers and was told they don't sell them separately. And if you could get one it's going to cost. Years ago the mid diaphragm alone cost the $200 to make. Now add in markup, etc.

Did I miss some intended joke or sarcasm?

He just wants to replace an existing blown diaphragm with it maybe?

Apparently beryllium, when used for both dome material and surround, is a bit brittle in the surround department and not as robust as other materials. As such, distortion, too much power, or a whoops with an interconnect or perhaps a turn-on transient could result in a dead driver. This is why some replace the original diaphragm with a Radian "Substitute" (I would not call it an equivalent in this case. Some even prefer the sound of the Radian diaphragm saying it is less laid back than the beryllium, but I have no idea why someone would pay the money for a TAD driver then use an aftermarket diaphragm...


Cheers,
Presto

Firstly it's hard for me to believe that pure beryllium metal is publicly available (it's a critical component of nuclear weaponry).

Secondly, beryllium metal shouldn't be touched or mucked with in anyway in a home environment. Small bits are very toxic to the lungs. If you need to, perform all operations with a serious respirator, mask & gloves.

beryllium is toxic in dust or vapor form. Once formed into the finished shape it can be handled with little or no danger.

If it was so toxic many audiophile connectors would not exist as many use beryllium copper alloys ( Z bananas and such). The old Shinon Red cartridge used a beryllium cantilever, but quit production because the Japanese maker had to comply with new OSHA type laws in Japan

In addition some tools are made with beryllium, particularly those in the gas industry, as beryllium tools are non sparking.

manufactures beryllium domes to fit 4" JBL drivers. I have heard that they are working on smaller domes also.


Installed one on a Edgarhorn midrange. The increase in performance was stunning: electrostatic like in terms of detail and speed. The only issue was the other drivers could not keep up

The V15 5 had a beryllium cantilever also and the Yamaha 100 speaker had domes for the mid and tweeter of the material. Focal make tweeters of it as does Scanspeak, etc., etc.

And a person / troll who cannot tell the difference is not going to be installing so much as a replacement driver, anyway.

Truextent sells replacement DIAPHRAGHMs, not drivers. They are sized to fit JBL compression drivers and the driver for which I changed the diaphraghm was a JBL unit used for Edgarhorn midranges. It is a 4 inch diaphraghm. According to one source Truextent is making other sizes to fit other compression drivers (Altec,perhaps) although I have not seen any on the market yet

What, are these only available through TAD for people with TAD drivers with TAD serial numbers?

I've replaced diaphragms in other professional quality drivers before... and once just for sonic reasons. What's the big deal?

Cheers,
Presto

"What, are these only available through TAD for people with TAD drivers "

Kind of.

The 2001 has a 48mm voice coil, most 1" drivers have 44.4mm voice coils.

Follow my link titled $800 if you need to buy one.

I find it absurd to suggest that end user is going to successfully attach a new Be diaphragm to the driver, as I said.

I'm sure all the non hobbyists here can properly align and adhere a new diaphragm to such an expensive driver.

No problem.

Meanwhile, check the resale value for speakers which have had so much as the crossover components replaced by the end user....

Most compression drivers are designed to be serviced you can easily replace diaphragms. Some while even in service maybe you could google search before getting so uppity.

 

I would say most could easily swap out for BE, posted on October 4, 2013 at 06:17:48

I am sure this person would have no trouble aligning or affixing a new BE diaphragm in a multi kilobuck speaker...because, after all, in such a product there are no tolerances or materials science involved.

These posters can't, even now, distinguish between "driver" and "diaphragm." Not after two days of this.

Welcome to my $40k diy speakers!

Hilarious.

Are you attempting to seem annoying or idiotic?

The TAD driver in question was designed by a JBL engineer to be field serviceable.

If a person is all thumbs, it might be a good idea to hire the work done (as with other things in life).

As most compression drivers are used in Sound Re-enforcement, field repair is a strong component in the design and manufacture process.


By looking at these videos, I think you will learn something, that appears you presently don't know.

TAD 4001 and 2001 are field replaceable and like the JBL in the videos listed, are simple to replace and alignment is already build in the driver design.

There is no glue, you are thinking of dynamic cone based drivers.

It is very certain you, who can not read, can't distinguish a diaphragm from a complete driver.....

For true TAD drivers and their replacement diaphragm, as well as JBL drivers location tabs are provided. The replacement DIAPRAHMS have a mounting ring attached with provision to match up to the locating tabs. Makes replacement a snap (this includes Altec Compression drivers, too)

Actually this all inane as I do not know how he got the idea that the OP want to adapt a beryllium diaphragm. There is nothing in the original post to indicate that, and it seems that he simply jumped to a conclusion that is totally unwarranted and unsupported.

What a troll..........

It doesn't take a special skill set. Anyone with basic tools who can follow simple directions can replace a diaphragm. There are alignment pins on the one-piece frame and diaphragm assembly that centers it perfectly with no special tools or instruments. The fastening hardware is then replaced and tightened, and it's done.

No adhesives are typically required. Some drivers might have gaskets which may or may not need replacing. The drivers I have worked on did not require gaskets or gasket replacements to change a diaphragm.

Seriously, it's not a big deal.

Cheers,
Presto

You can't understand him (I can't) but he takes a TAD 4002 apart.
