Do all, or most JBL woofers and mid-ranges have foam surrounds? I am mainly interested in speakers from the mid-70's to early 80's.
I notice many JBL's of this period need re-foaming of the surrounds. Kinda old and foam rots.
I am just an average DIY guy so I wonder about the difficulty and screw-up levels of doing it myself. I live in a rural area and the nearest good repair shop is 90 miles away. For me DIY is the way to go for most things.
On a scale of 1-10 (10 being most difficult) how would those who have done it rate the difficulty level. And who is the best source for the surround foam? Thanks, Jack
