I got this 10hz Bass test from some where, and I was like sweet I want to try this through my bass amp, I bet it will rock. Anyway I hooked it all up and started it playing, at first I couldn't hear anything so I cranked it way up. I still couldn't hear it to well but I sure as hell could feel it. I was like this is pretty cool, but then I looked done at the speaker cabs! The speakers were moving in slow motion back and forth about an inch each cycle!!!!!!!! They looked like the woofers on those huge 18s you see at concerts where it looks like the speakers are ripping themselves apart, but these were 10s and a 15! I quickly shut it off. Did I destroy my cones?!?!?!?!?!?!?
