Short answer: the Bowers & Wilkins DB3D. It ranks #8 of 73 subwoofers by sound quality, rated 3.7/5, at $4,500. The SVS 3000 In-Wall ranks #34, rated 3.3/5, at $1,999.99, $2,500.01 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Bowers & Wilkins DB3D is the better-sounding option. An exceptionally compact high-end subwoofer housing dual-opposed 8-inch Aerofoil cones with 1,000 watts of Class D amplification. The tradeoff: The 8-inch driver displacement limits deep sub-bass output below 30Hz; cannot pressurize large open-plan rooms.
What the SVS 3000 In-Wall does well: Independent CEA-2010 testing records 81.1 dB at 20 Hz and 108.5 dB through 40-80 Hz. The catch: Deep-bass output is modest next to a comparably priced box subwoofer, so it suits music and moderate home theater use rather than reference-level effects.
Buy the Bowers & Wilkins DB3D. It is rated higher for sound quality, and the $2,500.01 you would save on the SVS 3000 In-Wall does not close the gap.
