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 SVS SB12-Plus ranks #134 (rated 3.6/5) and is discontinued, so it is only an option used. The SVS SB12-Plus’s replacement, the SVS SB-2000 Pro, is rated 3.8/5 at $749.
The SVS SB-3000 is the better-sounding choice. 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.
Why pick the SVS SB12-Plus: A compact 12 inch sealed cube subwoofer with balanced and speaker level inputs, aimed at small rooms. The catch: Sealed output falls to 97.4dB at 25Hz, 89.8dB at 20Hz and 87.8dB at 15Hz, so deep movie effects are weak.
Buy the SVS SB-3000. It is rated higher for sound quality, and the SVS SB12-Plus is discontinued, so it is only available used.
