Has anyone tried using a M80 as a center channel mounted horizontally? I was advised by Axiom that there would not be a negative impact on the resonance of the speaker but I am wondering on how the dispersion of the high level fequencies would be (center the speaker under the screen or center the tweeters under the screen)?

I am asking becasue I would really like to use 5 identical full range speakers for SACD/DVDA (75% of listening time) but I do not have the space availabe under the projector screen come movie time to have the M80 in a vertical orientation. I suppose I could have a seperate VP150 for movies mounted above the screen and remove the M80 but it would be a shame to waste it...

Any advice or suggestions? Thanks.
