As a matter of interest does anyone know just what exactly is this material.
I'm just curious.

If "they" told you they'd have to kill you.
There are however some threads on the topic.
Is this breaking out thing AQUAPLAS?
How to re-coat those??
Thank you
Looks like it.
Recone time soon:

Try arguing "Warranty."
[Unlikely.... ]
Also, as a point of interest, I would like to know, just what does this magical stuff do? :dont-know
I know it must be special, because it is held in such great reverence around here that you would think it was the greatest invention since sex. Well, maybe not that great. But, still pretty high on the list.
What’s the technical low down on this stuff?

It adds mass and reduces resonance....
I am afraid those woofers are lost... fortunately new diaphragms are still made and available through any JBL authorized reconer or replacements are readily available via eBay. As Zilch mentioned, if you are the original purchaser of the speakers I'd expect JBL to pay for the recones under warranty.
5 Gallons!!!! You gonna treat your whole house with the stuff?

Perhaps some motivated soul could do a Zilch and order a 5 of said Antivibe and decant it into say half pint measures ( or perhaps even less ) in order that the needy can get some. I'm sure that with a bit of experimentation a hand application method can be devised ie. dabbing it on with a small sponge.
Zilch you are in the wholesale end of the rag trade ( never mind the quality feel the width ) are you the man ?
Actually the thrust of my query was not in relation to woof applications but rather HF diphragms. I have never seen this on a dome, anyone got a pic to satisfy my curiosity. It must be a pretty thin coating and furthermore is it prone to peeling off as on the driver above
You can use it on t-shirts. Application tolerances are much less critical. You might be wearing it right now.

If you know a custom t-shirt maker, that might be a way to access a trial quantity.
I,m just trying to fill a gap in my knowledge. Does it come in blue ?
Wasn't it determined some time ago that Aquaplas is Antivibe: http://www.blachford.ca/products/5_3.html Quote:"All of our materials are sold under the registered trademark Antivibe® and Aquaplas®."
As I recall, the biggest hurdle was that they required a minimum order of five 5-gallon pails or a 55 gallon drum...
Edit: OK - I found the original thread, though it appears a final consensus wasn't reached: http://www.audioheritage.org/vbullet...ead.php?t=6653

"In this application, the dampening material is highly effective in reducing vibrational resonance conditions in structures such as sheet metal panels. The dampening material is resistant to water and a variety of solvents, acids and corrosive gasses. The dampening material used in this application can be purchased from H. L. Blachford, Inc. and is sold under the trade name "AQUAPLAS" and can be purchased in sheet form or liquids. In this application, the "AQUAPLAS" sheets have a thickness of between about 6 mm to 10 mm. "
That's it the 5 gallon minimum. Good luck!! I have tried twice to get a 5 gallon pail no luck yet.

I just had two LE14A's and two 128H's reconed by JBLPRO and I was talking to him about the white cones and he told me the white is real fine ground up coral...how he knows I do not know but that is what he told me the white is real finely ground up coral that JBL uses on the cones
Here are the Impedance curves for with and without. There is a shift in the 2 peaks.
