Now some other thoughts, which may or may not be useful. If it was me, I'd do a full 5.1 setup (Beam, 2 PLAY:1s, and a SUB) in the Home Theater...and I might even consider a PLAYBAR instead of a Beam for the more expansive soundstage), and do just the Beam in the living room. Of course, that's depending on how much time you spend in each.
I tried to do just a PLAYBAR in my bedroom where I have my second TV, but soon ended up with another full 5.1 setup. Sonos can be addictive
