In your room the 180 should be all you need.

And really in my room other than that one seat, the 180 works fantastic. I know I will get a 180. I doubt I will ever run the dual M2 scenario above my TV to reach that single listening postion unless I have an amp with volume control to run the centers of off. I am pretty sure my wife would veto any dual configuration above the TV. I wonder if we could talk Ian into producing a 4 ohm M2 just for this purpose?
