View Full Version : JBL Century 100's: How to glue on G100 replacement frames?

04-30-2012, 06:56 AM
Years ago I bought a set of G100 replacement frames for my JBL Century 100's, as the foam grilles had disintegrated. Somehow, I never got around to installing the new frames, and they apparently were shipped without any instructions.

In the box with the frames was a tube of Bostic 4035 adhesive - with an expiration date in the year 2000! I found some replacements for the Bostic glue online, but I'm not sure how to go about gluing the replacement frames to the original Century wooden grille assemblies. I've scraped all of the remnants of the old foam off the grilles, so I'm left with a nice, clean surface of some kind of nylon mesh material, still stretched taut. You can see where the original glue lines holding the foam were located. Should I just use those as a guide?

Anyone know the best way to to do this?

TIA for your help!

I used blobs of silicon bathtub calk (got the small tube at Home Despot/Lowes) to glue the L100s foams I had to the nylon screen on the wood frames. I had basically created a bead near the edge and put a couple blobs near the center, but not where they would be over a driver. Gave it a full 24 hrs to dry before putting the frame back on the speaker & standing it upright and it worked great.
