We are looking into upgrading to our first Sonos system, I’m looking at an ARC ultra along with a sub 4 and two Era 300s as the rear speakers.
Primary use will be movies. We don’t want to do speaker stands and we don’t actually have a wall behind the couch for another 20 feet. Has anyone ceiling mounted the Era 300s? I read that in the settings you can invert them but does anyone have a similar setup and can make recommendations. Does it work well for surround sound / atmos experience?
