I found the JBL "Goop" guy !!!

[andrew_hofstett]

So please tell me..... has anyone followed up with the "goop guy sons" ??

Where's the goop??

And that's exactly the way it was used on the cloth surround of the JBL D123, to simply seal the surround cloth. I decided to use the same stuff primarily to prevent surround disintegration (and to a lesser extent, some damping) for the "F" series all paper cones.

Okay, where do things stand these days with the goop sourcing? I need some to make a repair on my Altec 414A's. Help!

Yes me as well. Cloth surrounds on the 2213's pretty dry......
The goop on my woofers is red....

Well I just purchased some new cloth accordion surrounds for my 414A's and with them came some stuff bottled up that the seller says is the right stuff. I will try it first on one of the ones I am replacing and see what it does. Looks and smells like standard aileens or PVA to me, but he says it is not.

I'm sure we'd all like to know about the goop ( ie; right-stuff ).

Seems to be staying "goopy" where I applied it to one of the old surrounds about a week ago. I will have to reach out to the seller and see if he will let on what it is. Or at least offer it up for sale on ebay.

If it's not red or brownish red, it's not the original adhesive/coating.
Might still be a suitable replacement, who knows.
I'm interested in this because after 30+ years of ownership, My 4312's decided to relieve themselves of it sometime within the last 6 months.
No changes in environment, nothing. Found it after my right side LE25-2 started buzzing.
Nothing was ever mentioned in the manual about rotating the woofers in a standard vertical installation to keep your goop....
We live and learn.....

On the 1501FE driver with cloth accordion surrounds, the coating is specified as Moyen SP706.

I'm not finding that via Google search, but Moyen is still in business.

They have a "cloth sealer" line of products listed, and their website indicates they will provide samples.

Might give them a call, describe what you need, and see if they can provide something that'll do the job.

On the 2216ND and 1501AL-2, the surround treatment is called out as Airflex 400, and it shows up in a search:
