Thanks for all of the quick responses.
I can not place them at the proper listening height due to a window on one side, and a doorway on the other. So, they will have to be at the ceiling. But I will try pointing them down.
As far as "trying" both positions, I don't really have that luxury as I only get one chance to do this. I don't have the time, nor do I want to have to come back and patch things up.
I will try the sides, slightly forward or rear of the listening positions.
I will let everyone know how it goes.
Thanks again!
