"The only good small sub is by Sunfire or Pinnacle but the SVS or HSU outperforms them in sound and price."
Hi Saturn
respectfully disagree. I auditioned the Sunfire True Sub - to me it sounded like a one note thumper. If you can find a Klipsch LF10 (1640 watts) grab one. I don't think they make them anymore, but you can probably get one for a very good price. Velodyne makes some excellent 10" subs as well. For effortless, musical bass I think you'll like the big SVS subs, but they're really big. Not wife pleasers.
