The Rythmik 12" subs (I own a pair) are very, very good for music. Some models from SVS, JL, and a few others probably outperform them <30hz (if you believe test results), but there's little to no music there. The variable "Q" is a great feature to help achieve seamless integration.
However, as usual, I agree with Bob. Bass management (I use Velodyne SMS-1 with an NHT x-2 active x-over, but SVS makes a competing unit that is well regarded) is critical to getting best results.
Good Luck,
Marty
