Short answer: the SVS SB-3000. It ranks #15 of 212 subwoofers by sound quality, rated 4.1/5, at $1,149. The Sony Bravia Theater Sub 9 ranks #84, rated 3.7/5, at $898, $251 cheaper, not enough of a saving to outweigh the sound-quality gap.
The SVS SB-3000 is the better-sounding option. A well made sealed subwoofer with tight, accurate bass and handy app controls, great for music and medium rooms. The catch: 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.
What the Sony Bravia Theater Sub 9 does well: A sealed dual 8 inch subwoofer with decent output for a mid-size room. The catch: The 390.0H x 400.0W x 350.0D mm cabinet and 51.4 lbs (23.3 kg) mass still need deliberate placement.
Buy the SVS SB-3000. It is rated higher for sound quality, and the $251 you would save on the Sony Bravia Theater Sub 9 does not close the gap.
