Table of Contents
If you want to add a little more oomph to your TV setup, but haven’t the room nor the cash for a beast like the Sonos Sub 4, then this Sonos Sub Mini is a great choice, particularly if you already own a Sonos soundbar. It comes with dual 6-inch force-canceling woofers, a sealed enclosure, Wi-Fi connectivity, and Sonos’ patented Trueplay tuning to deliver substantially deeper bass without requiring a large subwoofer cabinet. Its compact dimensions make it particularly well suited to Sonos Beam and Ray systems in bedrooms, apartments, and smaller living spaces. For existing Sonos users who want greater movie impact and fuller music reproduction without stepping up to a full-size Sub, it is a natural upgrade. Pick it up now for 20% off the MSRP!
At 8.98×8.98×11.93 inches, the Sub Mini is compact enough to fit into spaces where a larger home-theater subwoofer would be intrusive. Read below for more details on the various specifications, or see the foot of this page for more offers on subwoofers, soundbars, and bluetooth speakers.
What we like about the Sonos Sub Mini
Dual 6-inch force-canceling woofers
The Sub Mini uses two custom 6-inch woofers positioned opposite one another inside its sealed enclosure. Their inward-facing arrangement creates a force-canceling effect, reducing mechanical cabinet vibration and helping the subwoofer deliver substantial bass without introducing distracting buzz or rattle.

Sealed acoustic enclosure
Unlike a ported subwoofer, the Sub Mini uses a sealed cabinet. This gives Sonos greater control over the behavior of the dual drivers while its digital processing manages low-frequency output, helping produce tight, controlled bass from a compact enclosure measuring just 8.98 inches across.
Trueplay room tuning
Trueplay can analyze how the Sub Mini interacts with the acoustics of a particular room and adjust its response accordingly. This is particularly useful because walls, corners, furniture, and listening position can significantly alter low-frequency performance. Trueplay tuning requires a supported iOS device.
Wireless Sonos integration
Audio is transmitted through Wi-Fi, so the Sub Mini only requires a mains power connection rather than a signal cable running back to the soundbar or speaker. Setup and adjustment are handled through the Sonos app, making it easy to integrate into an existing Sonos system.
Compact 14-pound design
At approximately 11.93 inches high, 8.98 inches wide, and 14 pounds, the Sub Mini is considerably easier to accommodate than a conventional large home-theater subwoofer. Its cylindrical design is particularly appropriate for bedrooms, apartments, offices, and smaller living rooms where floor space is limited.
Designed for Beam, Ray and compact Sonos systems
The Sub Mini is particularly well matched to products such as the Beam and Ray, where a dedicated subwoofer can substantially increase low-frequency extension while reducing the bass workload placed on the soundbar. It can also integrate with other compatible Sonos speakers and systems.
Who should buy this Sonos Sub Mini deal?
The Sonos Sub Mini is designed for users who want substantially deeper bass from a Sonos system without the size and output capability of the full-size Sub 4. It makes particular sense alongside the Beam or Ray in small-to-medium rooms, where an enormous subwoofer may be unnecessary. It is equally useful for music, films, television, and gaming. Movie effects gain greater low-frequency weight, kick drums and bass lines become more substantial, and games can reproduce explosions and engine sounds with greater physical presence.
Its strongest advantage remains ecosystem integration. Users wanting a conventional subwoofer with universal RCA/LFE connectivity should look elsewhere, while existing Sonos owners benefit from straightforward wireless pairing, app control, and room tuning.
