Select a location

Choose a location—it’s designed to provide optimal sound wherever you place it.

Note:The Sub contains strong magnets. Don’t place the Sub near equipment that is sensitive to magnetic fields.

Attach the feet

If you’re placing Sub horizontally on a floor, you can attach permanent felt feet (included) to protect your floor. If you’re putting it on a rug or using it vertically, no need to adhere the felt feet.

Note:The felt feet are not removable—a strong adhesive will keep them permanently attached to the Sub.

  1. Lay the Sub down so the Sonos logo is facing down. Make sure you adhere the felt feet to the side that doesn’t have the Sonos logo.

  2. Place the enclosed guide on one corner of the unit and fold the flaps over the edge.

  3. Peel the backing off one of the feet.

  4. Press the felt foot (sticky side down) onto the unit inside the circular portion of the guide.

  5. Attach the other 3 felt feet the same way.

Connect the cables

Attach the power cord and plug in the Sub. Be sure to push the power cord firmly into the Sub until it is flush with the surface.

If you don’t have the app, download it from the app store. You’ll use it to set up and control your Sonos system. See Getting started. Make sure you set up at least one speaker before adding the Sub.

Note:After the Sub is paired with a Sonos speaker, you won’t see it displayed separately in Rooms. Any changes you make to that Sonos speaker (volume, mute, music selection) will also affect the Sub.
