I have Pioneer BS22's hooked up and hanging near the top of the screen, I play around quite a bit with them, and for music, usually leave them off, except for extended theater setting, which really provides more punch playing rock, at the expense of spatiallity ( did I just make up a word?). When on, in Dolby or THX modes, the front sound stage really seems to flatten out parallel to the big screen. My question would be angle for these speakers. I have them pointed downward several degrees. May have to play with that. Perhaps 90 degrees to the ceiling would help.
Why go out to a movie theater?
