The Move really isn’t designed for home theater use, although I suppose you could potentially connect it using the Move’s Bluetooth feature. But I wouldn’t want to guaranty any sort of lipsync, not to mention if the TV has the correct Bluetooth codec….and it would be only receiving a stereo signal across bluetooth. It’s just not designed for that type of use. Sonos sells the Arc and the Beam as home theater speakers.
But if they’re set up as two different “rooms” in the Sonos app, there’s no reason why they couldn’t both be playing at the same time.
Edit: using two different input signals, the Arc via ARC or eARC, and the Move via (hopefully) Bluetooth.
