FAQs

What is the frequency range of the Sonos Sub 4?

The Sonos Sub 4 has a frequency range of 0-25 Hz.

Can I use the Sub 4 with any Sonos speaker?

The Sub 4 is compatible with most Sonos speakers, but it is primarily designed to work with soundbars and speakers that can benefit from its enhanced bass capabilities, such as the Sonos Arc, Beam, Five, Era 300, and Era 100.

How do I update the Sonos Sub 4's software?

Software updates are done automatically through the Sonos app. Make sure your Sonos system is connected to the internet to receive updates.

Can I place the Sub 4 horizontally?

Yes, you can place the Sub 4 horizontally, such as under a sofa. However, consider the acoustics of your room and ensure it's placed in a location where the sound can propagate effectively.

What is Trueplay and why is it important?

Trueplay is a feature that uses the microphone on your iOS device to measure how sound reflects off the walls, furniture, and other surfaces in your room. It then optimizes the sound of your Sonos speakers to compensate for the room's acoustics, resulting in the best possible listening experience.

How do I factory reset the Sub 4?

Troubleshooting

Sub 4 not connecting to the network.

Check your WiFi connection and ensure the Sub 4 is within range of your router. Restart the Sub 4 and your router. If the problem persists, try connecting the Sub 4 to your network via Ethernet cable temporarily to update the software.

No sound or weak bass.

Verify that the Sub 4 is properly connected and powered on. Check the volume levels in the Sonos app. Ensure that the Sub 4 is correctly bonded with your other Sonos speakers. Also, check the physical placement of the subwoofer.

Trueplay tuning failed.

Make sure you have an iOS device. Ensure the device is connected to the same WiFi network as your Sonos system. Reduce ambient noise during the tuning process. If problems persist, try restarting the Sonos system and try the Trueplay process again.
