Can over tightening the screws that hold in a speaker cause it to vibrate and buzz when you play certain notes? Here's the full story. Ok, so I've been having trouble with a nasty buzzing noise in my speaker cab. This cab started this a few months back, I took it apart discovered three of the screws holding the speaker in were striped, I replaced those three with T-Nuts and machine screws. All was good, then a week ago the buzz came back. I decided it was time to replace all the screws (read about that adventure here). I've done that, but somehow the vibrating/buzzing has gotten worse. Anytime I play an F at anything close to performance volume I get a really loud buzzing sound. Because of the problems I've been having with this cab, I'm worried that I was over zealous when tightening the speaker screws. I did them each a little at a time, skipping my way around the frame so as not to warp the speaker, but I did make them pretty darn tight. My question is, could having them too tight cause this problem? Or do I need to try and tighten them even more? Any other ways to fix this sort of speaker vibration problem?
