The room is about 20x15x16 and the fronts and center will be mounted on a fireplace that extends out into the room. I'd like to do bookshelf m22s but the fireplace sticks out far enough that it blocks the formation of a complete soundstage. Towers won't work because there are built in bookcases and doorways on each side of fireplace. Yes I meant 6 ft between the L and R mounted on each side of plasma. My seating is more like 14ft away. Like I said nothing seems ideal.
