Hi stewboy,

As long as there is an inch or so of clearance for the port from the wall, you will be fine wall-mounting the M3ti's. It's important to stay clear of ceiling/wall/corner intersections to avoid unnatural emphasis of bass and upper-bass frequencies.

Keep in mind that if you mount them up high, the stereo soundstage might seem peculiar "way up there". This is a matter of personal preference and you might like the effect.
