I just built 3, 88 specials DIY speakers for my theater. I would like to place at least the center if not all of them behind the screen. Room is 145 inches wide and 20 feet long and 8 foot high. Right now I have a DIY 120inch wilson countertop screen with a Epson 5030ub projector. First row of seats is at 11 feet. I was thinking of just mounting the speakers on the wall and hanging the screen in the air. I have a drop ceiling also. Or if I really need to build a false wall and put the speakers in it. Not a huge deal as I built all the walls in the theater so extending one it's huge deal (just a huge mess lol). So any idea's are welcome. Would like to stay in the 140inch to 150inch diag or 127inch to 137inch wide size. Just hunting for ideas on the best way to go around doing this. Thanks for any input .. Here is a picture of how it stands right now with the new speakers for testing. Just ignore the high tech speaker stands lol Also there is a full size Marty Sub I have to put some where.
