Hi millerbrad,
Take your wife to a movie in a big cinema. Ask her to look at the ceiling before the lights dim. NO ceiling speakers, right?
The reason cinemas don't use them is that they don't work very well, and all movies are mixed with surrounds on each side wall, which is where you'll see the surrounds in cinemas and mixing studios.
Our spatial hearing is cued to lateral-arriving and front-arriving sounds, not to overhead sounds or sound directly from behind the head.
As was pointed out in this thread, think of suspending QS8s to each side of your listening area.
Regards,
