What SVS did you get? I have an SVS PCi 20-39 and it has always performed awesome for me. I got mine back when Axiom's subs weren't nearly as outstanding as they are now.

Have you tested your room for correct placement of the sub? I've had KLH speakers in my past as well, including their subs, and the SVS makes the KLH sound like the piece of cheap gear that the KLH is.
