You may want to also add a Seaton Submersive subwoofer to your list....
It is an incredible sub with some of the best SQ I have heard...
It is a Dual 15" firing Opposed Sealed sub.... I have heard lots and lots of subs, and this one is truly at the top of the heap and well worth the money.

If I hadn't built my own subs I would have bought those for sure...
