It's time to replace the surround on my B-380, and I'd really rather not pull the dust cap off unless absolutely necessary. I've replaced my 15" Tannoy surrounds with no problem, but I understand JBL voice coil gaps are extremely tight. I'd like to avoid pulling the cap to use shims, but a rubbing voice coil is no good either.
So what do people around here do when installing new surrounds? Thx.
