I am new to home theaters and have questions about my set up and choice of projector. I plan to purchase a sharp 12000 and fix a stewart screen in the wall. I will recess the screen (twice) and put felt over the setbacks. I at first planed on a perforated screen but I was told that the dlp would lose light and thus not give as good a picture. I have been reading that the best place to put the center speaker is behind the screen. Does it really make that much of a difference? The plans I had called for all three speakers to go behind the screen (120 in, should I go smaller?). On the same subject what does everyone think about the sharp 12k? I would appreciate any help or suggestions anyone might have.
