Great sound
Sonos is some good gear! The app needs work, it’s trying to be something it’s not, but otherwise, great product

Things to consider
This subwoofer is best for people already using compatible Sonos speakers or soundbars, so it is less flexible than specialist wired subwoofers designed for broader AV receiver-based systems.
Cinematic experience score
9/10 - powerful, room-filling bass adds strong impact to films and TV when paired with compatible Sonos home theatre products.
Room size suitability
Best suited to small to large living rooms and entertainment spaces
Music vs movie performance
Excellent for both, with slightly stronger appeal for movie and TV bass impact
Ease of setup rating
9/10 - straightforward setup for existing Sonos users with wireless integration and app-based control.
Multi-room flexibility
High within the Sonos ecosystem, with easy integration into multi-room Sonos audio setups
Key benefits
- 125W Output: Delivers strong low-frequency impact that adds more weight and drama to movies, games and music.
- Wireless Integration: Connects over WiFi to compatible Sonos setups, helping keep your room cleaner without a separate audio cable run.
- Flexible Placement: Can be positioned upright or laid flat, making it easier to fit beside furniture or under low units.
- App-Based Bass Control: Lets you adjust bass levels through the Sonos app to better suit your room and listening preferences.
- Clean Audio Performance: THD+N below 0.009% across 20 Hz-20 kHz supports deep bass with low audible distortion.
- Dual-Band WiFi Support: Works on 2.4 GHz or 5 GHz WiFi networks for easier integration into modern home wireless setups.
- Stable Cabinet Design: The 16 kg build helps keep the subwoofer planted in place during demanding bass-heavy playback.
- Sonos Ecosystem Compatibility: Seamlessly expands the low-end performance of compatible Sonos speakers and soundbars for a fuller home theatre experience.
Q: Does the Sonos Sub Gen3 work with non-Sonos soundbars or AV receivers?
A: No. The Sonos Sub Gen3 is designed to work only within a Sonos speaker system. It connects over Sonos wireless networking or Ethernet, and it cannot be physically connected to a traditional subwoofer output on a TV, soundbar or AV receiver.
Q: Can the Sonos Sub Gen3 be used on its own as a standalone speaker?
A: No. The Sonos Sub Gen3 is an add-on subwoofer made to extend bass in an existing Sonos setup, not a standalone speaker. It is best paired with compatible Sonos soundbars or speakers, where it handles low frequencies while the main speaker covers the rest.
Q: Can the Sonos Sub Gen3 be placed flat as well as upright?
A: Yes. The Sonos Sub Gen3 can sit vertically or be laid flat, which helps when fitting it beside furniture or under some low units. It is still a large subwoofer, so allow enough floor space and keep airflow around the cabinet unobstructed.
Q: Does the Sonos Sub Gen3 use Bluetooth for audio?
A: No. The Sonos Sub Gen3 does not use Bluetooth for audio playback. It works over Wi-Fi as part of the Sonos multi-room platform, with Ethernet available as a wired network option, so it is intended for integrated Sonos rooms rather than direct phone pairing.
Q: Can you adjust the bass level on the Sonos Sub Gen3?
A: Yes. The Sonos app lets you control the Sub's bass level, so it can add subtle low-end support at moderate listening levels or deliver much stronger bass when wanted. That makes it easier to tune the sound for movies, music and room size.
