Hi, folks. I am in the planning stages of a dedicated home theater in my basement. The room is unfinished (studs only), approximately 15'W X 22'D. The height is currently 7'6" floor to ceiling. I plan to put a drop ceiling in, bringing the height to 7'3". There is a 6" support beam that bisects the room (essentially two 11' rooms could be made). Here's my problem/question. I want to ceiling mount an FP to project onto a 90"-100" diagonal screen. Looking at the throw distance of my projector of choice (Panny 300), I would have to mount it about 12' back. This would put the projector behind the support beam, hanging down about 6'5" from the floor(to clear the beam). Seating would be about 11' to about 14' (2 rows of sofas, second row on a 6" riser). Will this pose a problem with viewing issues for the second row? Should the projector be mounted forward of the beam? I know it vents it's heat to the back, so it would need some space in front of the beam. Should I just dump the ceiling mount idea and go with a floor mount? A floor mount would present some wiring issues, I think. I wish I could lose the beam, but it does support the rest of the house! Moving the theater to another part of the basement would mean a smaller width (11'), below the bedrooms (it's a ranch style house), or too close to the heating system. Nothing is cast in stone yet, as the room is a "blank canvas". Any help/advice would be much appreciated!
