Just to chime in as a "defender" of the SVS subs. Yes, they are outstanding -- both HT and music. I also love the Hsu subs, so I am not dissing them at all. I happened to get an excellent deal on a used 20-39pci SVS sub. It shakes the house when it needs to (my fireplace has this funny resonance somewhere around 36Hz), but is incredibly tight and unobtrusive when reproducing music. I find it works well with a wide range of music, from classical to classic rock, blue grass to metal, and string quartets to Outkast.

The tube shape does make it a challenge to fit in in certain decors, and I probably wouldn't try to keep one under a desk since the top should not be obstructed (or at least that is my understanding).

Regards,
Rich
