I had purchased an Arc, Sub, and 2 SL’s for a home theatre configuration, replacing an ancient analog JVC receiver w/2 bookshelf speakers. We found we missed the stereo separation, so I purchased another pair of SL’s. But they cannot be added to the room the Arc is in - apparently the max for the Arc room is the sub and one pair.
The accepted workaround is to add the two new SL’s to a different Room, then configure them as a Group to play together while watching TV. Two major drawbacks to this:
1. Volume on TV remote doesn’t control the new Room
2. The 75 ms delay (inherent to Grouped rooms) is very noticeable
I have used Sonos for audio in a different room (I esp. like the dedicated wireless you get with the Boost) and have really enjoyed it. But I’ve paid a lot of money for this new Sonos home theatre and am sorely disappointed. If this is the best home theater that Sonos can provide, I plan on boxing up everything and sending it back for a refund.
Why on earth is it not possible to add more than three speakers to the Arc Room?
