Actually it is more of a demerit to have all of your speakers in the ceiling. If it is a HT room..the speakers should be in/or on the front, side and rear walls to give a true surround sound effect.
Putting all seven speakers in the ceiling is just the easy way out. The sound will lack luster.. regardless if you can tilt them or not.
