My wife and I recently purchased a new home. I’m finally getting my man cave back but need some advice on placement of my new home theater. Below are the room dimensions. Room dimensions The projector being used will be the BenQ 2150st. I know the Logitech surround sound isn’t the best but that’s what I currently have to use. I’ll be upgrading that unit in a couple of years. I’m focusing the money on the space itself, the projector, and screen. Questions: Which wall should the screen go on? (Orange, blue, or green) What size screen? I was thinking 120”. There are no windows so I’ll probably go with a white screen. What’s a good surround sound on budget? One that I could grow into, going from 3.1 to 5.1, would be best for budget. Any other advice you would give someone new who is on a budget?
