This would be incorrect. First, you need two speakers to act as surrounds, which would then be ‘in sync’ with the Ray. With a single speaker, you can set it up in a second ‘room’ in the Sonos software, which will be in sync when streaming music, but slightly delayed when playing the Ray’s TV (optical) input. 

Ok thank you for the reply. I appreciate your time. 

Hi,

When you say slightly delayed, how slightly? Is it very noticeable when watching tv?  I have a small room that is probably not big enough for 2 speakers so wanted to ask before buying the Ray as I already have the Era100 
 

Thanks

The minimum delay would be 75ms. Note that a single 100 cannot be “Bonded” to RAY as a surround speaker. The two surrounds must be identical models and Bonded to RAY. The single 100 will not provide surround audio. For many listeners the 75ms delay for a Room Grouped with RAY when RAY is playing TV is “tragic”, other listeners might not care. When playing a music source all Grouped Rooms will be time aligned.

Ok, thanks for that.

Just to confirm, if I have the Ray and one 100 era in the same room, can I link them together to play the same tv audio. Not surround, just the same audio. Is that where the delay would be? 

Yes, there will be a latency for the Grouped 100. At the potential cost of some lip sync you can fuss with RAY’s TV Dialog Sync. No guarantee this will workout well for you.
