Hi guys

Out of curiosity.  I have a sonos surround system with one Sonos Arc , 2 Subs Gen 3 and 2 Sonos one SL as surround speakers. 

I wonder, is the a way to connect two additional One SL to the same system ? 

A few weeks ago they upgrade the S2 to connect two Subs. I did buy another Sub Gen 3 and it is amazing how the system improves with two subs. 

I would like to add two more SL but I think us not possible.  Will it be ??

Sorry, this isn’t currently possible. The maximum number of channels the Sonos Arc setup can do is 5.2.2 which is what you currently have.

You could group two One SL’s to your 5.2.2 setup but they wouldn’t sound good because they would be playing all the channels, including dialogue, out of both speakers which would interfere with the multichannel surround effect in your room.


In addition, there would be a 75ms delay between the Arc’s room, and any room you grouped with it.
