Locate the Home Theater Room in a Dedicated Space
A dedicated home theater room is a room solely dedicated to watching videos on a big screen. This means that little else happens in that home theater except for screening-related activities. And today, screening means far more than it ever did, with streaming services like Amazon Prime, Netflix, and Hulu, BluRay movies, video gaming, and conventional cable TV.
When the home theater shares space with other activities, the cinematic experience is lessened. When the non-dedicated home theater shares open floor plan space with the kitchen, cooking sounds and smells invade. When the theater is the living room, kids run around and light is difficult to control.
Spare bedrooms work fine, but they do need to be long enough so that viewers can maintain a proper distance from the screen. This is especially important with video projectors. At the extreme end, a projector needs roughly a 14-foot throw distance in order to cast a 150-inch diagonal picture, though short-throw projectors are available.
