Couple meaning in a couple years, I am selling the house and when I buy another I will have a room or addition added on for that size.

Yes, what I was saying was with your diagram, my setup is pretty well on what you have in the diagram, save a few inches here and there. Right now I have no option to move my seating position. My speakers are a bit farther apart but toed in. I do not hear two speakers, I can actually use 2ch and one would think the centre channel is on.
I think, ( I cannot go back as I will lose this writing ) but you have the M80 37" to the front from the wall. I am 31" I go closer, because I do not have a sub and I get a bit more bottom end.
Thanks for your time on that diagram
