Sub 4
Overview
Overview
Sub 4 unlocks the full power of Sonos sound, delivering powerful bass to immerse you even deeper in every scene and song.
- Pulse-pounding bass. Dual Sonos-engineered drivers generate deep, dynamic low frequencies. The ported enclosure enhances the bass response so you feel every beat, roar, and rumble in your chest.
- Transform your home theater experience. Pair Sub 4 with Sonos Arc, or Beam for dramatically deeper bass and clearer highs that draw you deeper into movies, shows, and games.
- Bring your music to life. Hear the nuance in every note and enjoy a greater sense of spaciousness when you pair Sub 4 with Sonos Five, Era 300, or Era 100.
- Iconic design. With its elegant sculptural shape and updated matte finish, Sub 4 is designed to look great in your home and to match your Sonos speakers.
- Place it where and how you want. Sub 4 reliably connects to your Sonos soundbar or speaker over WiFi so you can place it anywhere in the room—even on its side and under your sofa.

Select a location
Choose a location—Sub 4 is designed to provide optimal sound wherever you place it.
- Use the acoustic slot as a handle to lift Sub 4 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 4 horizontally on the floor, don’t put anything on top of it. Leave at least 1" clearance along the top of Sub 4 if placing under furniture.
- Sub 4 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 4 either vertically or horizontally. If you’re going to use it horizontally, you can attach permanent felt feet.
Connect the cables
- Attach the power cord and plug in Sub 4. Be sure to push the power cord firmly into Sub 4 until it is flush with the surface
- 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.
Note: Make sure you set up at least one compatible speaker before adding Sub 4.
Sub Audio
Use the Sonos app to adjust Sub Audio settings:
- Go to System Settings
and select a room where you've added a Sub. - Navigate down to Sound and select Sub Audio.
| Setting | Description |
|---|---|
Sub | Toggle 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 Sub 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 (flip if you don't hear enough bass in your usual listening position). When a room with a Sonos Sub is tuned using Trueplay, phase control is set and can't be changed unless you disable Trueplay. |
Reset | Resets all Sub audio settings to their default values (0). |
Change speaker pairing
You can easily change the Sonos speaker your Sub 4 is paired with.
Note: If you unplug your Sub from power and plug it back in somewhere else, wait for the status light to stop flashing and turn solid white before changing its settings.
- Go to System Settings and select a room where you've added a Sub.
- Navigate to Products and select Remove Sub to get started.
You can pair the Sub 4 with a different Sonos product or choose not to use it right now. It will appear as "unused" in your list of products until you pair it with another Sonos speaker.

In the Sonos app:
