## Long description

The Sonos Sub 4 is an active subwoofer with a built-in D‑class amplifier designed to extend low-frequency reproduction for Sonos systems. It runs from AC mains (110–240 V, 50/60 Hz) and is available in black or white. Supplied with an AC cable, the Sub 4 pairs with Sonos soundbars and speakers to deliver deeper, more powerful bass for home cinema, music listening, and multiroom setups.
Advantages
Dual force-canceling woofers produce deep, dynamic bass while virtually eliminating vibration and distortion, and the ported enclosure enhances low-frequency output for a punchy, tactile response. The acoustic design offloads the lowest frequencies from paired speakers, allowing clearer mids and highs. Trueplay room tuning optimizes bass performance for your room, and WiFi connectivity plus simple setup via the Sonos app make installation quick and flexible. The sculptural matte cabinet is available in black or white and can be placed upright, on its side, or hidden under furniture.
Suitable for
Home cinema systems with Sonos Arc, Arc Ultra, or Beam
Music listening with Sonos Five, Era 300, or Era 100
Multiroom Sonos setups that need extended low-end
Rooms where you want flexible placement (upright, on side, or under sofa)
When it may not be suitable
If you already have very large, dedicated low-frequency speakers or a powerful standalone subwoofer that matches your room size, Sub 4 may provide redundant bass capability. It also requires a Sonos system to unlock full functionality and seamless integration, so it is not a standalone solution for non-Sonos audio systems.
Key specifications
Amplifier type: Built-in Class D amplifier
Power supply: AC 110–240 V, 50/60 Hz (supplied with AC cable)
Driver configuration: Dual force-canceling woofers in a ported enclosure
Connectivity: WiFi for system integration and streaming (no wired audio input required)
Placement: Upright or horizontal placement supported; designed to hide under furniture
Finish: Matte cabinet available in black or white
How to use
Plug the Sub 4 into mains power, open the Sonos app, and follow the in-app steps to add the subwoofer to your Sonos system. Pair Sub 4 with a Sonos soundbar or speaker to assign it to the desired room. Use Trueplay (where available) via the Sonos app to tune the subwoofer for your room acoustics. For deeper, more cinematic bass, add a second Sub 4 and pair both with an Arc or Arc Ultra.
What to consider before purchase
Requires a Sonos system for full integration and app-based setup
Ensure available mains power (110–240 V) and WiFi coverage in the intended placement area
Consider room size and existing speaker setup to determine if one or two subwoofers are appropriate
Usage recommendations
Place the Sub 4 where it fits and sounds best—upright for visibility or horizontal under furniture to hide it. Run Trueplay tuning after placement and, if possible, pair two subs with Arc or Arc Ultra for the most immersive low-end.
