Ok, everybody's been saying how it's better to overpower a cab than to underpower (sic) it, and thus I'm in the process of getting a Sansamp RBI with a 1400W power amp BUT. If the worst damage to the speakers is done by clipping the amp and by doing so causing distortion, and if a clean signal is the only thing healthy to the speakers, what about distortion effects? I play in a metal band and usage of some kind of fuzz is crucial to being heard from under two loud guitars. Even studio engineers want to use distortion on the bass to make it audible. Am I killing my speakers by doing this?
