Hi pitbull24,
The QS8 surrounds are very adaptable and forgiving. They can be wall-mounted as high as 3 or 4 inches from the ceiling, leaving just enough room for the top-firing driver to reflect its output from the ceiling.
I really advise you not to use ceiling speakers. It's not how movies are mixed and played back, and our ears/brain are keyed to lateral-arriving sound and delays. Ceiling reflections certainly add to the wash of envelopment, but you do not want in-ceiling speakers to be the supplier of surround content.
Regards,
Alan
