Short answer: the REL Acoustics HT/1510 Predator II if sound quality matters most, the SVS PB12-Plus if price matters most. The REL Acoustics HT/1510 Predator II ranks #71 of 97 subwoofers at $2526.62. The SVS PB12-Plus ranks #72 at $1499, $1027.62 cheaper.
What the SVS PB12-Plus offers: Independent CEA-2010 testing records 110.0 dB at 20 Hz and 118.0 dB (avg of 3/4 bands) through 40-80 Hz. The ported, front enclosure with 12” (305mm) driver with ported design has the headroom for demanding film bass in a large room. Watch for: The 558.8H x 502.9W x 675.6D mm cabinet and 57.6 kg mass make this a serious placement and moving commitment. Ported output does not solve room modes, so careful placement and calibration remain essential.
What the REL Acoustics HT/1510 Predator II offers: Independent CEA-2010 testing records 98.0 dB at 20 Hz and 118.1 dB through 40-80 Hz. The sealed enclosure with 15” (381mm) driver delivers substantial upper-bass output for movie effects and music. Watch for: Deep-bass output is more limited than the strong 40-80 Hz result suggests, so it is not the right choice when the lowest movie effects are the priority. The 457.2H x 541.0W x 492.8D mm cabinet and 45.2 kg mass still require deliberate placement and calibration.
