Short answer: the Perlisten Audio R212s. It ranks #71 of 109 subwoofers by sound quality, rated 4.1/5, at $5,000; the BK Electronics Extreme ranks #106, rated 3.4/5, and costs $5,995, so there is not much of a tradeoff to weigh.

Why pick the Perlisten Audio R212s: Independent CEA-2010 testing records 102.7 dB at 20 Hz and 119.2 dB through 40-80 Hz. 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.
Why pick the BK Electronics Extreme: Massive 15-inch with 1000W RMS delivers startling speed like fast car with powerful engine.
Buy the Perlisten Audio R212s. It is rated higher for sound quality than the BK Electronics Extreme and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

Perlisten Audio R212s: $5,000 eBay
Pros: Independent CEA-2010 testing records 102.7 dB at 20 Hz and 119.2 dB through 40-80 Hz. The sealed enclosure with 2x 12” (305mm) drivers 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 599.4H x 408.9W x 500.4D mm cabinet and 48.1 kg mass still require deliberate placement and calibration.
