The Two Speakers In Full
SVS PB-5000 R-Evolution: $2,599.99 SVS eBay
Older model: the SVS PB-4000 (rated 4.2/5).
Pros: Ported 15-inch high-excursion driver with a 2,000W RMS dual-monoblock amplifier and variable port tuning. SVS rates extension to 13Hz. The SVS Subwoofer Control app adds DSP control and Auto EQ room calibration.
Cons: No independent measurements yet, so its output can’t be compared with ranked subwoofers. A large ported cabinet needs deliberate placement, and ported output does not solve room modes on its own.

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.
