You can never have too much bass in your expensive home theater. Sonos fans can now link two Sonos Subs together to add some extra boom to the living room. But in typical Sonos fashion, you have to meet a few requirements before installing your dual subwoofers.
The first requirement is a Sonos speaker or amplifier. The Sonos Sub will not work without Sonos Arc, Beam, Playbar, Playbase or Sonos Amp. You also need the latest version of the Sonos 2 app (Android / iOS) and a 3rd generation Sonos Sub. The second Sub in your lineup may be an older model, but Sonos says you need the extra processing power of a 3rd generation Sub to make the magic happen.
