Just curious about the recommended distance for M80's.

My speakers are 5.5ft apart and I sit at a distance of 7.5ft from the left or right speaker when I sit in my center spot.

Does Axiom have a recommended minimum distance for how far back one should be for a given distance between the left and right speaker.

I'm also curious if at my given distance Axiom would recommend toeing the speakers in or are the M80's at the spread and distance I have, totally not necessary as they are forgiving enough. I did try them toed in and not toed in but really don't think I've heard much of a diff.
