SVS PB-4000: $2,158.97 Amazon eBay

SVS PB-4000 ranking card

Pros: Independent CEA-2010 testing records 115.3 dB at 20 Hz and 120.3 dB through 40-80 Hz. The ported, front enclosure with 13.5” (343mm) driver with ported design has the headroom for demanding film bass in a large room.

Cons: The 594.4H x 520.7W x 703.6D mm cabinet and 69.5 kg mass make this a serious placement and moving commitment. Ported output does not solve room modes, so careful placement and calibration remain essential.
