This CERTAINLY cannot replace the masterful guide that Bo wrote in July 2003, but can be used to augment it. I HIGHLY recommend reading that first. It can be found here:

Recently there was a question about refoaming and reconing brought up and I thought I would show this as it might help someone. I want to stress that I have some basic mechanical and some decent electronic skill, but prior to joining this forum a few months back had never done a resurround or recone. IMHO doing a recone with an original JBL kit is easier than a resurround as, as far as I'm concerned, there are fewer things to screw up. For example, when you do a recone there are fewer things to damage when cleaning up the gluing surfaces during preperation, as the cone, spider and voice coil are not in play. So......
I started with a JBL 123a-1 woofer. You can see that I have cleaned up the gluing surfaces at the surround edge and the spider mounting surfaces. Not surgical, but I believe sufficient.
