No Brainer
If you've got the dough for Paradigm Reference, there's two killer subs in that family to choose from. Once again, it all comes down to size...
If you've got the space: Servo 15
If you don't: Seismic 12
I've got the PW-2100. It was the
only small sub in the price range I was researching that passed my torture test of Massive Attack Mezzanine, and didn't bottom out during Star Wars Episode II Chapter 2 (I think, where Amidala's ship lands on Couroscant). My room is over 3,000 square feet, and this little gem energizes it easily. I have yet to bottom it out even at reference levels of Bjork's Hyper-ballad (Post).
I've personally got a woody for the Seismic 12, the output and quality of it's bass it's unbeleiveable...then you look at how small it is! Then you try to pick up this 14" cube and it weighs 70lbs! Best subwoofer ever if you ask me. You can hide it and your buddies will wonder where the hell all of the bass is coming from! It's what I want anyway.
Check out these reveiws, they're rediculous:
