I have owned a pair of JBL Jubals since approx 1974 and continue to enjoy them regularly. Both woofers (126 A ) have been reconed one or two times. Recently I noted the absence of bass from one of the speakers and pulled it out of the cabinet. The spider has come loose from the basket but the foam and cone look good. I have read all the posts using 'adhesive' to search and have seen responses ranging from cyanoacrylate to 2-pt epoxy to silicone RTV.
My question is two part:
1) can I just reglue this and what type of adhesive will work best?
2) if I need to send them out again who in the field is recommended to do the repair? I'd like them to hold up for somewhat longer than the last repair which lasted only a few years. I don't abuse them but they are driven hard at times with a reasonably low distortion HK amplifier and mostly digital signals. BTW- I do have teenagers that have come to appreciate their quality and I don't always know what goes on when I am not home.
thanks in advance for any input to my first post on this forum
