Short answer: the Perlisten Audio R212s. It ranks #87 of 143 subwoofers by sound quality (rated 4.1/5) at $5,000 and is still sold new; the BK Electronics Extreme ranks #140 (rated 3.4/5) and is discontinued, so it is only an option used.
The Perlisten Audio R212s is the better-sounding option. A sealed dual 12 inch subwoofer with strong, punchy upper bass for movie effects and music, plus XLR and RCA inputs. 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: A big 15 inch subwoofer with a powerful amplifier and continuous phase control for flexible setup, now discontinued. The catch: It weighs 200.6 lbs (91 kg), which takes two or more people to move and needs a strong floor.
Buy the Perlisten Audio R212s. It is rated higher for sound quality; the BK Electronics Extreme is no longer sold new.
