Concrete Vault Home Theater - Lots of questions

post #1 of 3
Thread Starter 
I recently finished building our new house, and am now getting ready to finish construction on the theater below the garage. The three car garage floor is a 3" concrete slab on top of wood framing, and under that is a 8'7" high space with a poured concrete slab, that houses the house mechanicals in one spot, and the rest will be the theater. 3 walls, the floor and the ceiling are all concrete, and the walls are 12" thick, so there is only one wood framed wall currently.

I am attaching two pictures below that show the room and a floorplan to help illustrate what I am talking about.

The first questions I have are these:

1. Is it a good idea to mount the front center channel just below the screen?

2. I am planning an IB sub array either in the front left corner, or below the center channel and screen in the center. Probably (4) 15" or 18" subs, using the space behind the screen wall (2' x 8'7" x 14'). Which location would be better? Would this amount of subs be sufficient for the space? What drivers would be recommended for this setup and how much power to drive them?

3. I am contemplating mounting the surrounds at the wall-to-ceiling corners facing down at an angle. Is this ok? What would be better? (Note - the seating will be flush against the left hand wall.)

4. What is the approximate distance a ceiling mounted projector needs to be away from the screen for a 9' screen? I am going to do the screen as a 2.35:1 with hinged black panels to hide the edges for 16:9. How far from the screen should the seating be? (There will be two rows of couches/seats and the back row is an eating bar with stools) How high off the floor should the screen be?

5. Where can I buy a popcorn and soda dispenser cheap?

1. No. Behind or above.
2. For that room, 3 or 4 subs...only 1 in a corner and easily moved. The rest spaced around the side and back of the room based upon a response model to reduce modal nulls.
3. Seating within 3.5' of a wall will also get very uneven response. Di/bi polar speakers should be mounted above ear level approximately 1/2 way between ear height and the ceiling.
4. No clue. Depends entirely on the projector and lens combination you select.
5. No, sorry. (e-Bay?)
