Hey - I'm an idiot about this stuff, so pardon the dumb question.
I've had two beta 202 cabs die on me in the last couple months (with different amps), both times it just fades out very quickly but doesn't sound like speakers are blown. I guess maybe the wiring is frying or coming loose? They're in sort of rough shape but the original speakers are pristine, and it doesn't look/feel like anything's wrong with the speakers, is it possible it's just the wiring?
