The compact wireless subwoofer for bold bass—

  • Instantly adds a dimension of deep bass impact to your audio listening experience.
  • Dual force-canceling woofers neutralize buzz and distortion.
  • A compact interpretation of our premium wireless subwoofer that's ideal for a small or medium-sized room, and low to moderate volume levels.
  • Mix and match Sonos products to create your wireless sound system, and add on any time.
  • See Setup when you’re ready to add Sub Mini to your Sonos system (make sure the Sonos product you plan to use with Sub Mini is already set up).

Controls and buttons


Center tunnel

Efficiently moves air to maximize bass.


Ethernet port

Use an Ethernet cable if you want to connect to a router (optional).


AC power (mains) input

Use only the supplied power cord to connect to a power outlet. (Using a third party power cord will void your warranty.) Be sure to use the proper power adapter for your country.


Status light

Displays the product's connection to WiFi, indicates when the volume is muted, and signals errors. Learn more

If the light is distracting, you can turn it off in your room’s settings.


Join button

Press to connect during setup.

Select a location

For the best sound experience, place Sub Mini upright near the speaker you’re going to use it with. The center tunnel can face in any direction.

If you place Sub Mini against a wall or your furniture, leave enough clearance for air to move freely through the center tunnel.

Note: Make sure the speaker you're pairing Sub Mini with is already set up in your system before you add Sub Mini.
Learn more about compatible products.

Connect the cables


Attach the power cord and plug in Sub Mini.


Download the Sonos app from the app store if you don't already have it. You’ll use it to set up and control your Sonos system. See Setup for more information.


Trueplay puts professional-grade tuning in the palm of your hands. Using the microphone on your iOS device (running iOS 8 or later), Trueplay measures the unique acoustics of your space, then optimizes the EQ so the bass never sounds muddy, harsh, or flat.

  1. Select > System, and pick the room you want to tune.
  2. Choose Trueplay Tuning. During tuning you'll move around the room holding your mobile device.

Note: Trueplay tuning isn’t available if VoiceOver is enabled on your iOS device. Turn VoiceOver off in your device settings before tuning your speakers.

Change speaker pairing

You can easily change the Sonos product Sub Mini was paired with during setup.

Sub Mini is compatible with most amplified Sonos products running S2 software. It's recommended for use with Beam, Ray, One, One SL, and Symfonisk products. Learn more

  1. If you move Sub Mini to a new room, plug it back in and wait for the status light to stop flashing.
  2. Go to > System and choose the Sonos product Sub Mini is paired with.
  3. Tap Remove Sub, then pair Sub Mini with a different Sonos product.

Note: When Sub Mini is paired with a Sonos speaker, you won't see it displayed separately in your system. Any changes you make to that speaker, like volume, mute, or music selection, will also affect Sub Mini.
