We are building a house and I am trying to figure out where I need to put wiring. I'd rather add it now rather than later. The room is ~14'6"x19'. My wife would not let up on the windows on the sides as she sees it as a game room rather than a theater, whatever, I can deal with that I think. We won't have the money right away for theater components so that isn't an issue yet however I plan on putting the components under the screen up front in a base cabinet.
My questions if anyone can help:
Is it best to plan for in wall speakers or normal speakers?
Is this room large enough for side speakers or is 5.1 enough?
I have an outlet in the ceiling just behind the barrel dome which is ~17' from the wall. Is this too far for a projector?
If I only do 5.1, how far back should the rear speakers be? Against the back wall or more to the side?
The doors are 8', if I do put the rears at the back wall, will that be too high (it's a 10' ceiling)?
What wires should I run from the front wall (components) to the projector? RG6, Cat6, HDMI etc
