I am running a 9.2.2 Dolby Atmos system and I'm using 4 of these... two for my sides and two for my rears. The angled delivery works just as I'd have hoped. Being in a large basement, I wanted to have my rears way behind me but also didn't want them sitting in the middle of the room. These guys delivered in a big way.
As my sides, they are a bit high but I was dealing with windows and doorways that prevented me from installing in-wall speakers at listener height.
Incredible sound and SUPER easy installation.
