That picture is from when I was doing many experiments, I actually run the M22s as far out as possible leaving them 2-3 inches away from the wall to the side and from the rear port. The mantle is a little shy of 5' off the ground(that is an 8' high ceiling) and I have 1" rubber self adhesive feet stuck to the back of the speakers to give them a little angle down. I think you will have no problems with your set up.
