Sonos Arc
I treated myself to the new Arc and have to say it puts the playbar in the shade. But now I'm standing like a donkey in front of the mountain... I still have 2 play 1 and 2 one sl with sub. I want two of the four speakers on the ceiling. How does Atmos "come out" there? I thought the Arc passes on the signals. But how? I can only connect two boxes. Do I still need a reciver or something?
