Short answer: the REL Acoustics HT/1510 Predator II. Both are rated 4.1/5 for sound quality (#82 and #70 of 110 subwoofers), and the REL Acoustics HT/1510 Predator II costs $2,526.62 against $2,599 for the SVS PB17-Ultra R-Evolution, with sound quality a draw, the lower price decides it.
Why pick the SVS PB17-Ultra R-Evolution: Independent CEA-2010 testing (Standard Mode) records 113.9 dB at 20 Hz and 119.4 dB through 40-80 Hz. The tradeoff: At 167 lbs with recessed feet that leave little clearance, moving or repositioning this cabinet is a two-person job at minimum.

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.

REL Acoustics HT/1510 Predator II: $2,526.62 eBay
Pros: 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.
Cons: 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.
