I've attached a pic of my current set-up, my front speakers are all installed in-wall. I don't have a lot of room in the rear behind the sofa to install speakers and am trying to weigh up what would be better, either the QS8 or go in-wall again to match the clean look of the front.

Would the QS8 be a better fit given it's design for surround and better handle the closeness of the listener, or would there be any argument to get say an M3 or M22 in-wall pair other than due to budget or for aesthetics?
