Magnepan3.6 placement

I am interested in getting a pair of 3.6's but am concerned about my room. They are going in my basement I can get them far away from the wall but my ceiling is at one point 74in then the high point is 83in. The 3.6's are 71in., will this present a problem does anyone know??
With the stand is about 72" high, I think it will present a small problem, but you can overcome it,

no problem, just give them back wall breathing room and lots of juice
I put 4 tiles each of "accoustic foam on my ceiling at a 45 degree angle from the speakers and listening chair.

It does fine.

I had my 3.6's in a similar situation. They sounded great. Keep them away from walls, but ceiling height is irrelevant.
