I moved the speakers around some more. Moving them out to 10' of separation (equilateral triangle) didn't help much. I moved them forward about 1 1/2' in front and 2' wide of the TV and that helped but I think that was more of a near field effect. I also moved myself around the listening area with little effect. I'm thinking the hard, high gloss drop ceiling may be the primary culprit.

I'm still planning to try the M60s in the family room and try the family room's good sounding bookshelf speakers in the problem room.
