Sonos Sub Mini - Compact Wireless Subwoofer with Deep Bass

Our review of the Sonos Sub Mini finds it best suited to listeners who want significant low-end impact from a small footprint. Paired with Beam, Ray, One or One SL, the Sub Mini delivers room-filling bass that noticeably deepens TV, movie and music playback without the bulk or rattle of larger subs. Setup is straightforward through the Sonos app and the sealed cabinet with dual inward-facing woofers produces rich, controlled low frequencies that feel larger than the unit itself.

Key Features

• Compact design: Small footprint lets users place the subwoofer anywhere in the room without compromising the strength of the bass.
• Dual custom woofers: Inward-facing woofers create a force-canceling effect that reduces distortion and keeps low notes tight and clear.
• Acoustically sealed cabinet: The sealed enclosure produces full-toned bass that sounds like a bigger subwoofer while avoiding buzz or rattle.
• Advanced processing: Built-in processing enhances bass response for cinematic depth and consistent performance across content types.
• Trueplay tuning: Room-adaptive tuning adjusts the bass to the room's acoustics so notes are not harsh, muddy, or flat; requires a supported iOS device.

Who It's For

The Sub Mini is ideal for people with limited space who still want impactful low end for TV, gaming, and music and who already use or plan to use Sonos speakers like Beam, Ray, One or One SL. Its compact size makes it a natural fit for apartments, bedrooms, and secondary listening rooms.

Those who need wireless compatibility with non-Sonos systems or who cannot use the Sonos app should look elsewhere, and users seeking earth-shaking reference-level bass for very large rooms may prefer a full-size subwoofer instead.
