A:Answer Hello!
Thank you for your interest in our Surround Speakers.
At the current time, only 2 Surround speakers can be paired to the Soundbar 700. When these are paired, the Soundbar itself will act as the front middle, front left and front right channels, whilst the surround speakers will act as a rear left and rear right. The Bass Module(s) act on a separate channel (The 1/2 in 5.1 or 5.2), so you can add more than one of these to a system.
We hope this helps answer your question!
