Short answer: the SVS SB-2000 Pro. It ranks #72 of 212 subwoofers by sound quality, rated 3.8/5, at $749; the Sonos Sub 4 ranks #10, rated 3.7/5, and costs $899, so there is not much of a tradeoff to weigh.
Why pick the Sonos Sub 4: A wireless subwoofer for Sonos soundbars and speakers, with force-cancelling drivers and setup from the Sonos app, placed near any outlet. The tradeoff: No independent measurements yet, so its output can’t be compared with ranked subwoofers.
Why pick the SVS SB-2000 Pro: A compact sealed 12 inch subwoofer with tight bass and full app control from your seat. The catch: Output is modest next to larger or ported subwoofers: Erin’s Audio Corner measured about 102.5dB at 20Hz, and he judged the SVS SB-3000, about $200 more, the better value for its considerably higher output.
Buy the SVS SB-2000 Pro. It is rated higher for sound quality than the Sonos Sub 4 and costs less, which makes it the one to get unless you need something the other one does better.
About the ratings: the Sonos Sub 4’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 3.5 to 3.9, so this verdict could change once it is measured.
