Hi everyone, first time poster. Well, I'm building a theater space.. The problem I'm having is the room dimensions.. 19 ft long, 10 feet wide after drywall. My problem is seating.There is no room for risers.. The ceiling is too low. I'm getting a projector, with a 110" screen.The speakers are behind the screen, and surround in the ceiling. What would anyone suggest for seating? Thanks
