I am building a custom house, the basement will be unfinished. I had the architect remove most of the lolly columns and install bigger beams to open up the floor plan. I increased the ceiling height to 10ft. My concern is in the HT room I have a beam that runs the width of the room around 8ft from the designated screen area. This beam will drop down about 8" I believe, making the ceiling height at that location approx. 9'4". The room is 15' x 20'. I had planned on 100-120" screen, will the beam dropping down hinder the FP from projecting to the screen? I believe I would have to place the projector about 12-14' feet from the screen. I can upload a jpg of the blueprint later tonight if anyone needs to take a look. Any comments? Thanks.
