Sonos Sub by Sonos Inc. - wireless bass module boosts home cinema sound

Sonos Sub adds a dedicated wireless subwoofer with dual force-cancelling drivers to Sonos home theater setups for deeper bass at home. This product is driving the price of Sonos Inc. stock (ISIN US83570H1086).

Sonos Sub sits like a glossy black slab on the living room floor, the central cut-out framing a circle of light from the TV. Each bass hit from an action movie ripples through the sofa, while Sonos CEO Patrick Spence talks about listeners wanting "more emotional impact" from their sound systems.

Wireless bass for Sonos setups

Sonos Sub is a wireless subwoofer that pairs with Sonos soundbars and speakers to add low-frequency punch down to 25 Hz according to the manufacturer’s specs. Its dual force-cancelling drivers face each other inside the cabinet to reduce cabinet vibration and rattling.

The unit connects over Wi-Fi and is controlled through the Sonos app, which lets users fine-tune bass level and room settings without a physical remote. A long rectangular form with a central hole makes it easy to slide against a wall or under a console, keeping cables and hardware visually quiet.

Design, drivers and placement

Sonos Sub uses two 6-inch class D amplified drivers positioned face-to-face with a sealed acoustic architecture, which Sonos says cancels out internal vibration. The glossy finish on the current Sub can show fingerprints when you move it, but once in place the rounded edges and central aperture blend into dark furniture.

Users can place the Sub upright against a wall or lay it flat under a sofa, provided there is enough clearance for driver movement. Sonos product manager Ryan Taylor has described the design as a way to "hide the hardware and feel only the bass" in earlier interviews with audio press. Rubber feet keep it stable on hard floors.

Integration with Sonos Arc and Beam

Sonos positions the Sub primarily as a companion for its home theater soundbars such as the Arc and Beam, where it takes over the lowest frequencies to free the soundbar for mids and highs. In a typical Arc plus Sub setup, explosions and bass-heavy music tracks move largely through the Sub, while dialogue stays anchored at the TV.

During calibration, the Sonos app runs the Trueplay tuning routine on compatible iOS devices, using the phone microphone to measure room acoustics and adjust the Sub’s output. Reviewers at What Hi-Fi have noted that with Arc and Sub combined, the system produces "deeper, more controlled" bass compared to Arc alone, especially at higher volumes.

Setup, app control and everyday use

Setting up Sonos Sub follows the same pattern as other Sonos components: plug in power, open the Sonos app and add a new product, then assign it to a room. The app walks through pairing with a soundbar or stereo pair of speakers and then offers a slider for subwoofer level.

Once running, the Sub reacts to source changes transparently. Switching from a Dolby Atmos film on a streaming box to a stereo Spotify playlist, the bass stays consistent as the Sonos system handles upmixing and downmixing internally. Reviewers at The Verge have praised the Sub for "clean, musical" bass that avoids a boomy sound when properly tuned.

Pricing, generations and markets

Sonos currently sells the latest-generation Sub on its own website in markets such as the United States, Germany and the United Kingdom, typically at a list price around 799 EUR in Germany and 899 USD in the US. Retailers occasionally discount it during sales tied to major shopping events.

The company notes that the Sub is compatible with virtually all current Sonos home theater products and many older speakers, but not with portable-only models like Roam when used alone. In Sonos’s pricing ladder, the Sub sits as a premium add-on, with the smaller Sub Mini offering a lower-cost alternative for compact rooms.

Sonos Sub’s role for Sonos Inc. stock

For Sonos, the Sub helps increase average revenue per household by turning a single soundbar purchase into a multi-component system over time. That strategy supports the home theater segment, which Sonos often highlights as a key contributor in its earnings calls. Sonos Inc. stock (ISIN US83570H1086) trades on Nasdaq in USD.
