I have a Dining Room/Kitchen room, and open to that is the adjacent Living Room. Currently I have two Sonos Ones paired with an original Sub. I have ordered a Beam 2/mini-sub/2 Era 100’s for the Living Room, which is where the TV is. It is sad that Sonos does not let me share the Sub with Both rooms, but what are you going to do?
My guess is that the original room DR/K, which is where I play music from Spotfiy, would benefit most from the Era 100s. If that were true, then I would make that room with the Era 100s and the original Sub. The Beam, for the TV room, would be paired with the mini-Sub and the Ones. Do you think this is sound reasoning? Finally, would it ever be a good idea, musically, to play music to both rooms simultaneously? Each room is about 12’ x 12’
