Hi, all. Building my basement starting next week. Bought a 10' (diagonal) screen that will be mounted behind the sheetrock in the ceiling, to a joist. DLP projecter will be mounted on the ceiling. Current speaker plan is 5 or 7 identical monitor-style (smaller) speakers, plus a subwoofer. Speakers are not purchased or even identified yet, all my money is going into building the basement first. Problem: Center channel speaker cannot go behind the screen (there is a window there, and some closets), or below the screen (open floor must remain open, due to spousal requirement), or in front of the screen (would block projected image, as screen will way up against the ceiling). The only option is above the screen, looks like. I can build a recessed box in the ceiling for the center speaker (with binding posts in it for electronic hookup). Question: Should I do the same for the front side speakers also, or can they be mounted just directly to the ceiling? Will having the center speaker higher up, in a recessed box, and the front side speakers slightly lower, mess up the front sound field? This is my first home theater, indeed my first surround sound, and I've read 3 books on the subject so far, in an effort to get the room construction correct the first time. I welcome any comments!
