i want a sub woofer that is at least as loud as my old sub woofer which is a Kove Armageddon that i estimate hits 145db's, and I would like it to be of great SQ, I want accurate bass for all types of music whether its techno or rock, and i want it to be able to hit really deep, i'm not asking for incredible loudness at these deep frequency's i just want to be able to easily hear them, because my kove whenever it trys to hit anything below 25hz i can't even hear it unless i really focus on it. so i just want a deep bass response down to atleas 20hz but i want it to have good SQ and have a flat response curve for anything above 28hz.
