save your money & check out vmps subs - easily the best-quality low-frequency reproduction at anywhere near the price. no amplification included, & the option to provide your own x-over make for superior electronics as well. even when factoring amplification & x-over costs into the equation, it's still a bargain compared to the powered subs. check out the output, distortion, & frequency specs on these - the best in the industry. many mfr's don't even give all this info. i know ya don't listen to specs, but in this case, they tell the story - vmps subs are *accurate*.
doug s., no affiliation w/vmps, other than being a satisfied customer.
ps - my system is music-only, i don't watch movies...
