Perhaps I am off base and just not knowing..
But if you have an issue with the tweeter for the center speaker and the second row, would you not have the exact same issue for the Left and Right speaker also? The Center is not like a Sub where you can set all the high frequency to be crossed over to it.
Yes dialog for the most part is in the tweeter range, and most movies dialog comes from the center channel as people talking generally are mid screen, but you can and will get just as much higher frequency from the Left and Right too.
I would say that if you have an AT screen and can get away with aligning the M60's to all be at the same height across the front, then you would get perfect timber matched sound and by far a better sound experience for everyone.
I have to agree with Oakville....you can't beat 3 identical speakers as your front soundstage,anytime you turn a speaker horizontal it is a compromise ( one which most of us have to do..) but I think you will be happy either way.........or will you?
My 1.5 cents
