This client wanted the A/V equipment in the living room to be as least noticable as possible.  We started with 65in Sony 4K HDTV on a low profile tilt mount.  Then we went with all in-wall speakers to keep them as out of sight as possible.  Finally we finished off the sound with a in-wall subwoofer.  Everything is controlled via a Control4 handheld remote for a super easy to use system.
