We just purchased a home and will be turning the basement into a theater. The basement has two sections both 9 ft trey ceilings totaling about 2200 sf. The front part we plan on making into the theater and putting a pool table in the back near the bar. The area is about 20 by 25 and would need a motorized screen to drop down in front of a fireplace.
My initial thought was 400" screen with HH contrast and 3d capable projector somewhere about $3,500 for the projector and what ever screen I need to achieve 3d hd cinema quality.
