Hello Friends!
I refoamed a lot of JBL 10" drivers (2121, 2122, LE10 etc.). The problem always was that the foam was to thick and therefore to stiff. The speakers never reached former specs again. Fs was mostly shifted up to 10Hz!
This company is the ONLY company I found delivering the right 10" foam surrounds.

The foam is called 10" JBL-3
Yes, even the kits from Rick Cobb are too thick. He delivers excellent kits, but the 10" I bought where too thick.
Pic1: completely wrong foam, much too thick
Pic2: better foam (Ricks version)
Pic3: right foam (Audiofriends)
