[QUOTE="shrapnel, post: 8625988, member: 625333"] The loss of bass jumping from .5 Ohm to 2 Ohm is as laughable as buying a 21,000W amp that has a 1A fuse. Impedance has nothing to do with frequency response. If an amp is rated 20Hz - 20kHz, it will cover it completely over whatever load is connected, if its there. The lower the impedance, the easier it is to get higher power out... that's it. period. And as long as the amp supports the impedance, you're safe. (now about that 21,000W amp I mentioned @ 1A... no way, not even at the mains voltage of your home.... you're source would have to be at least 21,000V with 100% efficiency.) EDIT: when I say Impedance has nothing to do with frequency response, that isn't exactly true... for an amp though it pretty much holds true within usable impedance and frequency... impedance and frequency are best related at the speaker level and has little to do with the amp itself.
