Commonly flagged

Sonos Trueplay tuning not yet optimized for 2.1 (sub-included) configurations

Where reviewers disagree Single-source only, so no cross-source comparison is possible. The one accessible whitelisted review evaluated the Sub as a supplement to a Sonos Era 300 stereo pair rather than as a standalone Gen 3 subwoofer, and the only dedicated Gen 3 review located (PCMag) was inaccessible/paywalled, so its verdict could not be corroborated. No tester published measured numbers for this exact model.

adding the Sonos Sub still brought dramatic improvements to some material

The floor-sitting sub also enhanced the surround-sound experience environmentally, making the whole room rumble.

Source: sonos.com (verified 2026-07-11) · corroborated by hifireport.com. The official Sonos product page (sonos.com/en-us/shop/sub) identifies the model as "Sub (Gen 3)" priced verbatim at "$799", and lists the Tech Specs used here: "Both Class-D digital amplifiers" (class-d), "Dual acoustic ports" (ported enclosure), "Frequency Response: As low as 25 Hz", Trueplay room calibration and app EQ (roomCorrection true), WiFi wireless setup (wirelessInput true), dimensions 15.31 x 15.83 x 6.22 in, and Weight 35.27 lbs (16 kg). The HiFiReport review corroborates the exact Gen 3 model (released June 2020), the force-cancelling dual inward-facing driver design with an individual amplifier per driver, the ~25 Hz low end, Trueplay, and an approximate 36 lb weight / ~15 x 16 x 6 in size — confirming this is the Sub (Gen 3), not the Sub Mini or another variant. Note: Sonos's own on-page comparison table shows a conflicting "29 lb" figure, but the dedicated Weight spec field (35.27 lbs) matches the review's ~36 lb, so 35.27 was used; driver size and amplifier wattage are not published by Sonos and frequency response is given only as a low bound, so those keys are null.
