I'm buying a new house and in the basement, I will have a dedicated home theater room with perfect light control (no windows in the room).
The room will be 11'6" W x 17' deep (ceiling height is 7'6").
I would like to have a front projection setup.
The room will be a flat black color. In order to help acoustics a little, the room will also have carpet flooring, dual layers of sheet rock, sound deadening insulation in walls and ceilings, a heavy full wood door.
I was thinking of getting a JVC DLA-RS55 projector (Pro series equivalent to the DLA-X70) with a Stewart Filmscreen Luxus Deluxe Screenwall StudioTek 130 G3 fixed screen (100" diagnoal, 16:9 format).
I have been reading a lot on projector placement, and I wanted to know your opinion on this model. I went on Projector Central's website and used their calculator to figure the best possible placement for my projector.
I will be wall-mounting it.
It has a projection throw ratio of 1.40-2.80.
I was told that the further back the projector is, the less zoom you use hence a sharper picture with no distortion. If I mount the projector too close to the screen, I'll be using too much zoom, and that's not a good thing apparently.
My seats have to be positioned exactly at 10 feet from the screen, due to rear speaker placement.
If I leave 1' of clearance in back of the projector, this means that the lens would be at a throw distance of 14'3" from the screen, using a 1.43x zoom factor. Is this good??
Or should I leave even less space behind the projector (say 6 inches instead of 1 foot) and reduce the zoom a bit more?
I've included a picture so you see a brief outline of what the room will look like...
Projector size: 7.1" x 17.9" x 18.6" (H x W x D)
Screen size: 49" H x 87" W
Screen size with frame: 55.5" H x 93.5" W
