Simple wireless connection to your chosen soundbar or speaker
More energy efficient and increased processing power & memory over previous generation
No Buzz or Rattle
Pure Soul-Shaking Bass
Upgrade your Sonos setup with bass you can feel in your chest. With dual Sonos-engineered drivers, Sub 4 delivers deep, dynamic low frequencies while a ported enclosure boosts the bass response for more dramatic impact.
The acoustic architecture of the subwoofer creates a force-cancelling effect that ensures no buzz or rattle and virtually zero distortion.
Craving more bass? Pair two with Sonos Arc Ultra or Sonos Arc for cinematic bass that shakes your soul.
From Movies to Music
Upgrade Your Sonos Setup
Sub 4 can add extra oomph to any Sonos soundbar or speaker running on the S2 Sonos app (excluding portable speakers).
Adding Sub 4 does more than add bass as the subwoofer takes the load of the lower frequencies, enhancing the high and mid frequencies from your connected soundbar or speaker for greater clarity and precision.
Pair it with a pair of speakers such as Sonos Era 300 or Sonos Five for a stereo setup made for bass lovers. Or create the ultimate Sonos Home Cinema Bundle when you add Sub 4 to the Sonos Arc Ultra and Era 300 rears.
Designed to blend in
Versatile, Sleek Design
Now available in an updated matte finish, Sub 4 retains the sleek styling of its predecessor and is designed to look at home in your space.
Not everyone has the optimal room layout; Sub 4 can be placed wherever works best for your space. You can even lie it horizontally under your sofa!
*Avoid placing in a very confined space.
Trueplay Tuning & Plug 'n' Play Setup
Optimised For Your Space
Sonos’ Trueplay technology ensures your setup performs best in your space, optimising the performance for the acoustics of your room. No need to worry about bass sounding harsh or flat, even if you place your sub by a wall or under the sofa.
Simple Wireless Setup
Setup is quick and simple! Just plug into power, open the Sonos app, and wirelessly connect Sub 4 to your chosen Sonos setup. Connecting over WiFi, there’s no need to worry about extra wires or placement.
What's The Difference?
Sonos Sub 4 vs Sub (Gen 3)
Sonos Sub 4 replaces the previous generation Sonos Sub (Gen 3). Both are suitable for a medium-sized or large room and moderate to high volume levels.
Sub 4 boasts a new matte finish compared with Sub (Gen 3)’s high-gloss finish. The latest generation also boasts increased processing power, memory and new WiFi radios over previous generations, making this Sonos’ most advanced sub to date. It also uses fewer materials and is more energy efficient.
Which Is Right?
Sonos Sub 4 vs Sub Mini
Sonos Sub 4
Recommended for Arc Ultra, Arc, Beam, Era 300, Five & Amp and best for a medium-sized or large room and moderate to high volumes.
Sonos Sub Mini

Can I connect Sub 4 to a third-party soundbar, wireless speaker, or Bluetooth speaker?
