Thanks Mojo. Yes, that sounds like a bit much for what I have in mind. My "reference thump" actually comes from my car stereo, (Jeep Cherokee Infinity system with a small factory sub, guessing maybe an 8" woofer).

When I listen to the bass in the car the music just has a great lively punch to it that I've yet to be able to reproduce in my home theater room. Maybe it takes a smaller woofer size to generate the slamming mid-range bass?

As a side question, how do these SVS box subs compare to their cylindrical counterparts? Have you guys done any comparisons of those?
