I see where repeatedly everyone on this forum raves about the SVS PB2+ ($1199 at 18"x25"Hx28"). I searched around and found Velodyne SPL 1200 ($830 at 15"x15"Hx16") and Sunfire True Sub II ($1100 at 11"x11"x11") appear to have about the same market price. Everyone seems to claim that SVS has bigger bang for the buck. Does the PB2+ excel above these? I gather the size of the speaker itself is a drawback compared to the others.
