I have an SVS 20-39PC+ This subwoofer puts a smile on my face every time I hear it. It goes down DEEP, and it's powerful. I've also heard the Hsu VTF-2, and that is also an impressive sub. If you decide on SVS or Hsu, you will not be disappointed. The SVS seemed to be a bit more bang for the buck so I decided to take that road myself. mikebaby
