Sonos Sub Mini (Black)

Product Overview

The Sonos Sub Mini wireless subwoofer adds deep, controlled bass extension to compatible Sonos soundbars and speakers in commercial AV environments where a full-size subwoofer is not practical. Designed as a compact wireless subwoofer for AV systems, it pairs directly with the Sonos Beam, Ray, Era 100, One, and One SL without requiring additional cabling between components. Its sealed cabinet and dual force-canceling woofer design minimize mechanical vibration and distortion, making it suitable for conference rooms, huddle spaces, and commercial meeting rooms where audio quality matters but physical footprint is limited. Available in Matte Black.

Product Description

The Sonos Sub Mini uses two 6-inch inward-facing woofers mounted in a force-canceling configuration, where each driver works against the other to cancel the vibrations that cause cabinet resonance and floor buzz in conventional subwoofers. This approach allows the Sub Mini to be placed on a shelf, equipment surface, or floor without the mechanical noise associated with ported or passive radiator designs in smaller subwoofers.

The sealed cabinet design contributes to the Sub Mini's low-frequency accuracy: rather than relying on port tuning to extend bass response, the sealed enclosure provides tighter, more controlled bass down to 25 Hz. This is particularly relevant in conference rooms and boardrooms where excessive low-frequency energy can create room modes that interfere with speech intelligibility. The Sub Mini adds weight and presence to music and content audio without overwhelming the speech range.

Two Class-D digital amplifiers power the dual woofers, with each amplifier tuned to the acoustic characteristics of the sealed cabinet. Class-D amplifiers produce minimal heat relative to their output, which is an advantage in enclosed AV furniture or rack-adjacent installations. The Sub Mini connects to the Sonos system entirely over Wi-Fi — there is no audio cable between the Sub Mini and the paired soundbar or speaker. Pairing is completed through the Sonos app in a few steps, and the system handles latency compensation automatically.

Trueplay room calibration, available via the Sonos app on iOS and Android, uses the device microphone to measure the acoustic response of the room and adjusts the Sub Mini's output accordingly. Auto EQ with the paired Sonos product ensures the crossover between the soundbar and subwoofer is set correctly for the room, reducing the need for manual tuning by the installer. For Sonos Beam Sub Mini pairing, this means the installer can complete setup and calibration without external measurement tools.

An Ethernet port provides a wired network connection option for RF-dense commercial environments where Wi-Fi congestion is a concern. Power supply is internal and universal (100–240V), with no external power brick required.

Frequently Asked Questions

Q: Which Sonos products is the Sub Mini compatible with?
A: The Sub Mini pairs with the Sonos Beam (Gen 1 and Gen 2), Ray, Era 100, One, and One SL. It is not compatible with the Sonos Arc, Sonos Sub (Gen 3), or Era 300 as a sub pairing.

Q: Does the Sub Mini require a wired audio connection to the paired soundbar?
A: No. The Sub Mini connects entirely over Wi-Fi. There is no audio cable between the Sub Mini and the paired Sonos device. Pairing is completed through the Sonos app.

Q: Can the Sub Mini be placed inside AV furniture or under a table?
A: Yes. The sealed cabinet design and force-canceling woofer configuration minimize vibration transfer, making it suitable for placement inside enclosed furniture or on shelves. Adequate ventilation is recommended to prevent heat buildup around the unit.

Q: How does Trueplay calibration work with the Sub Mini?
A: After pairing, the Sonos app guides you through a Trueplay measurement using the microphone on an iOS or Android device. The app plays test tones and adjusts the Sub Mini's output to compensate for the acoustic characteristics of the room. Auto EQ also sets the crossover balance between the Sub Mini and the paired Sonos product automatically.

Q: What network infrastructure is required for the Sub Mini?
A: The Sub Mini requires a 2.4 GHz or 5 GHz Wi-Fi network (802.11a/b/g/n). For installations in RF-dense environments, the Sub Mini's Ethernet port can be used for a wired connection instead. All Sonos devices on the same account should be on the same network subnet.

Q: Is there an external power adapter required?
A: No. The Sub Mini has an internal universal power supply (100–240V, 50/60 Hz) and connects directly to a standard power outlet. No external power brick is required.

Q: What is the warranty on the Sonos Sub Mini?
A: Sonos provides a one-year limited warranty covering manufacturing defects from the date of purchase.

Q: Can the Sub Mini be used in a commercial installation with a control system?
A: Yes. When integrated into a Sonos system, the Sub Mini's volume and EQ settings are managed through the Sonos API, which is accessible to third-party control systems including Crestron and AMX. The Sub Mini itself does not have a separate control interface — it is managed as part of the paired group.
