Short answer: the Sonos Sub 4, if you are buying new. The Sonos Sub (Gen 1) measures as well as it (#102 vs #10 of 73 subwoofers, 3.7/5 vs 3.7/5) but is discontinued, so only consider it used; the Sonos Sub 4 is still sold new at $899.
What the Sonos Sub 4 does well: A wireless subwoofer for Sonos soundbars and speakers, with force-cancelling drivers and setup from the Sonos app, placed near any outlet. The catch: No independent measurements yet, so its output can’t be compared with ranked subwoofers.
The case for the Sonos Sub (Gen 1): A wireless subwoofer for Sonos systems that stands upright or lies flat and pairs with simple setup, now discontinued. Watch for: It works only within a Sonos system, so it cannot serve as a conventional standalone subwoofer.
Buy the Sonos Sub 4 if you want one new; the Sonos Sub (Gen 1) is discontinued, so only look for it used.
Worth knowing: the Sonos Sub 4 has not been measured yet. Its rating is estimated from related models, with a likely range of 3.5 to 3.9, so treat this verdict as provisional.
