Actually, why couldn't both hallways be part of the theater and the door flipped to the back right instead of the back left?....
Anyhow, I have almost EXACTLY the same measurements happening in my theater, I have a 140" wide 2.35:1 screen and a cursed beam running right across the middle of the room. There are a bunch of pics in my build thread, but I'll repost a couple here now. Here's a picture of looking toward the front wall of my theater:
and left wall looking toward the rear:
I'll be building a perimeter soffit and box in the beam across the middle at the same soffit height to make it an architectural element.
As for the projector, there isn't much you can do about the fact that the projector's light beam needs to clear the steel beam. I explored four options:
- Buy a projector that has a short-throw lens option and mount the projector off the ceiling, just in front of the beam. RESULT: No projector lens could reasonably fill that size screen with that short of throw distance
- Buy a projector with a short throw lens option and mount the projector on the underside of the beam. RESULT: same as above
- Buy a projector that has a long-throw lens option and fire the projector under the beam from the back of the room OR put the projector outside the room and fire through an optical viewport. RESULT: Would be preferred for my setup, but projectors with these lens options typically start around $20,000 and go up from there, so not an option because it is a budget-buster.
- Mount the projector in the 16' to 17' sweet spot from a post mounting coming down from the ceiling with the light beam just clearing the steel beam. RESULT: - The option I am going with.
Considering my second row of seating is at an 18' distance to the screen, I am going to try and either slightly advance the seating and/or slightly push back the projector so it ends up over the heads of the second row / over the potential back bar area.
The all-in option not mentioned above is to hire a construction company to pack out and recess the steel beam up into the ceiling. Had I known / realized the situation with this beam I would have paid the extra $$$ during construction to recess the beam. Now I am stuck with it and trying to make lemonade out of lemons.
