[QUOTE="Wonderbread, post: 76395, member: 541455"] Sensitivy is measured as SPL with 1 watt @ a 1 metre distance. so basically, its a measure of how effiecinetly the driver uses the power presented to it. A hgih number is more efficient, and will play better with fewer watts, (less wasted power). As far as i know, it does not affect distortion, except in a lower powered situation. Frequency response is basically the range of tones taht the driver can play. the human hearing scale goes from 20 hertz up to 20 thousand hertz... different types of speakers are designed to play different ranges. Subs generally from under 100 hertz. or at least the perform teh best at those freq's... basically look for a driver that gets low (20-25 hz) but 30 is fine, and ahs a good sens. if you are not going to be able to throw a nice big amp at it..
