FAQs

Can I use two Subs with one soundbar?

Yes, many Sonos soundbars support a 'dual-sub' configuration for even more powerful and balanced bass across larger rooms.

Do I need a special cable to connect it to my TV?

No, the Sub connects wirelessly to your Sonos soundbar, which in turn handles the connection to your TV via HDMI ARC or eARC.

Can I lay the Sub on its side?

Yes, the Gen4 is designed to be placed upright or laid flat on its side to fit under couches or other furniture.

Is the Sub compatible with non-Sonos speakers?

No, the Sonos Sub is designed exclusively for the Sonos ecosystem and will not pair with third-party audio equipment.

Does the Sub come with a power cable?

Yes, a standard power cable is included in the box.

How do I tune the Sub to my room?

Use the Trueplay tuning feature within the Sonos app, which uses your mobile device's microphone to measure how sound reflects off walls and furniture.

Troubleshooting

The Sub is not detected by the Sonos app.

Ensure the Sub is plugged in, the status light is flashing green, and your mobile device is on the same WiFi network.

The audio sounds muddy or distorted.

Check your room settings in the Sonos app to adjust the Sub level or re-run Trueplay tuning if your environment has changed.

Intermittent connection dropouts.

Move the Sub closer to your wireless router or ensure no large metal objects are obstructing the signal path.
