What is a wireless subwoofer?

A wireless subwoofer connects to other speakers over your WiFi network. Sub does not have a battery and therefore requires AC power.

Can I hardwire Sub to my soundbar or speaker?
Sub connects to Sonos soundbars and speakers over WiFi.
Do I have to set Sub up at the same time as my other speakers?

No. The Sonos sound system is designed to be modular. You can add Sub at any time.

Can I connect Sub to a third-party soundbar, wireless speaker, or Bluetooth speaker?
Sub will only connect to Sonos soundbars and speakers over WiFi.
Will Sub work with third-party wireless or Bluetooth speakers?

No. Sub will only connect to Sonos speakers over WiFi.

Do I need Sub to create a 5.1 surround sound?

Yes. Sub is the “.1” element of the 5.1 system that takes over all low frequency sound.

Can I use Sub with my passive or wired speakers?

If you power your speakers with Amp, you will be able to connect Sub as part of your Sonos sound system.

Does laying Sub on its side affect the sound quality?
Lower frequencies are omnidirectional, which means the direction or orientation of Sub does not significantly affect the sound. Placing Sub in a very confined space, however, could affect the dispersion of the sound.
If I position Sub on its side or under my sofa, will it cause vibration or buzzing?

No. Sub features two internal drivers that face each other for a force-cancelling effect. Note that placing Sub in a very confined space, however, may affect the dispersion of sound.

If I have Sonos speakers in various rooms, will placing Sub in the center of my home improve the bass of my entire system?
Sub pairs with speakers in a particular room. Walls create a natural barrier to sound dispersion, so pairing Sub with speakers in other rooms would result in imbalanced sound, with lower frequencies playing in one part of your home and higher frequencies in another.
