I hate people who have such lovely, neat homes. (it's just pure jealousy )

Just like everyone else, ceiling mounting is what occurred to me. I notice you have two spots in the "back" of the room marked "speaker connection" but I don't see anything in the photos. Can you elaborate? Are there some wall plates behind the curtains in those locations?
