Ok, I have a peavey 4x12 cab, but one of the speakers is starting to go bad, and before it decides to explode on stage with me, I want to replace it. I want to get one as cheap as humanly possible, but I'd like it as new as possible too (but am willing to go used). Anyone know of a place where I can look for one? I think this one will last me for awhile, cos it only has this, horrible (no other way to explain it) sound when I have the amp cranked (Acoustic B320), but still, I don't want problems with it. Thanks!
