I am building a Home theater system for my home. I would like to use a rear center channel. My surrounds will be inwall on the back wall. My problem is I will have a window in the center of that wall so that I don't have room for a rear center speaker. Has anyone tried one in the ceiling? My seating will be about 2 feet from the back wall which would put the center ceiling speaker almost directly over the seating area. Some one said to direct the tweeters back against the rear. Any help will be appreciated.
