SONOS Sub Wireless Subwoofer
Sub
Sonos Sub takes your audio experience to the next level
- Instantly adds a dimension of deep bass impact to your audio listening experience.
- Pair Sub (Gen 3) with any other Sub and feel the bass from every corner of the room.
- Allows placement anywhere because it’s wireless and compact—position it vertically or horizontally on any floor surface.
- The top of the acoustic slot doubles as a handle so you can lift it.
- Sub (Gen 3) is compatible with Sonos S2 Sonos only (for Android and iOS).
- See Getting started when you’re ready to add a Sub to your Sonos system.
Note: Sonos Sub is designed for use with most Sonos speakers, except
Sonos Connect, Port, and Move. Make sure you set up at least one speaker
before adding Sub. 
Controls and lights
Select a location
Choose a location—it’s designed to provide optimal sound wherever you place it.
- Use the acoustic slot as a handle to lift Sub out of the box. You should always bend your knees when lifting heavy objects to avoid undue stress on your back.
- Make sure at least one side of the slot is free from obstruction. If you place it vertically against a wall, don’t block the front opening. If you place Sub horizontally on the floor, don’t put anything on top of it.
- Sub is designed to sit on the floor. You can place it in a corner, against the wall, behind, under, or next to any piece of furniture on any kind of floor surface.
- Position Sub either vertically or horizontally. If you’re going to use it horizontally, you can attach permanent felt feet (available upon request, contact Sonos Support). See Attach feet (optional) for more information.
- Make sure at least one side of the rectangular opening (acoustic slot) is unobstructed.
- If you place Sub vertically flush against a wall, don’t block the front acoustic slot.
- If you place Sub horizontally on the floor, don’t put anything on top of it. Leave at least 1″ clearance along the top of Sub if placed under furniture.
Note: Sub contains strong magnets. Don’t place it near equipment that is sensitive to magnetic fields.
Attach feet (optional)
If you’re placing Sub horizontally on a floor, you can attach permanent felt feet (available upon request, contact Sonos Support) 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 Sub.
- Lay 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.
- Place the enclosed guide on one corner of the unit and fold the flaps over the edge.
- Peel the backing off one of the feet.
- Press the felt foot (sticky side down) onto the unit inside the circular portion of the guide.
- Attach the other 3 felt feet the same way.
Connect the cables
Attach the power cord and plug-in Sub. Be sure to push the power cord firmly into 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 Sub.
Note: After Sub is paired with a Sonos speaker, you won’t see it displayed separately in. Any changes you make to that Sonos speaker (volume, mute, music selection) will also affect Sub.
Sub settings
Sub’s settings are set during the initial setup process, but you can make changes anytime.
- 1. Go to the sound settings for the room that’s associated with your Sub. It appears as a room (+Sub) in your list of rooms.
- Tap Sub Audio.
- Choose one of the following options:
- Sub: Choose On or Off to turn the sound from Sub on and off.
- Sub Level: Use the slider to increase or decrease volume. (You can use this setting to match the subwoofer level to the level of your main speakers.)
- Phase Control: Choose 0° or 180° to set the phase control for your Sonos Sub or third-party subwoofer. This can help integrate your subwoofer with other speakers in the room. (You’ll see this setting when you pair a Sonos Sub or third-party subwoofer with a Sonos Amp or Connect: Amp.)
- Crossover Frequency: Adjust the frequency at which the sound transitions to the subwoofer. By default, this is 80 Hz.
- You may wish to choose a different crossover frequency if:
- The main speakers sound distorted at high volumes—moving to a smaller speaker size setting can help.
- Your attention is drawn to Sub’s location while listening to music—moving to a larger speaker size setting can help.
- Recalibrate Sub. If you move your Sub to another location, purchase new speakers, or just want to adjust the sound after the initial setup, you can recalibrate Sub (Android devices only).
- Select the size of your stereo speakers (Connect: Amp only).
- Press Play to compare the volume of two test sounds, A and B, and then select No Difference, A is louder or B is louder.
- Press Play to listen to a test sound, and then select the level you prefer.
Pair Sub with a different speaker
You can easily pair Sub with a different Sonos speaker (except the Sonos Connect). If you’re moving Sub to a new room, wait for the status light to stop flashing after you plug it back in.
- Go to the sound settings for the room that’s associated with your Sub. It appears as a room (+Sub) in your list of rooms.
- Remove Sub.
- You can pair Sub with a different Sonos product or choose not to use Sub right now. It will appear as Sub (unused) until you pair it with another Sonos speaker.
