Also, distortion DOES NOT BLOW SPEAKERS! Think about it, if distortion blew speakers, then how the hell could anyone ever listen to Nirvana, any punk band, 60's music, etc. A speaker will produce whatever signal is fed into it until it's physical limits are reached, which can ONLY happen with too much power (unless the speaker is defective). Can a "500 watt" amp blow a 600 watt speaker? For the most part yes. But, that's because a true 500 watt amp should be capable of transients in the range of 1000-2000 watts. If the input is clipped (maximally driven), then it's possible to nuke the driver.
