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.

Connect a second Sonos subwoofer to your home theater setup for even deeper, room-filling bass.
In the Sonos app:
- Go to System Settings and select a room where you've added a Sub.
