Short answer: the SVS SB-3000. It ranks #15 of 212 subwoofers by sound quality (rated 4.1/5) at $1,149 and is still sold new; the Q Acoustics Q B12 ranks #68 (rated 3.8/5) and is discontinued, so it is only an option used. The Q Acoustics Q B12’s replacement, the Q Acoustics Q SUB120, is rated 3.8/5 at $1,399.
The case for the SVS SB-3000: A well made sealed subwoofer with tight, accurate bass and handy app controls, great for music and medium rooms. The tradeoff: Being sealed, it gives up deep-bass output: Audioholics measured 96.6dB at 20Hz and 101.7dB at 25Hz, about 15dB behind the ported SVS PB-3000 from the same series, so a large room or reference-level movie bass may call for a second sub.
The case for the Q Acoustics Q B12: A sealed 12 inch subwoofer for music and movies that is easy to place in tricky rooms, now discontinued. The tradeoff: Rated response starts at 28Hz, and output falls to 95dB at 16Hz, so the deepest effects are limited.
Buy the SVS SB-3000. It is rated higher for sound quality; the Q Acoustics Q B12 is no longer sold new.
