Here are my components:

Marantz VP4001 (http://us.marantz.com/Products/1908.asp)
4:3 84" wide First Generation Firehawk Screen

Here is the geometry of the room:

I will be throwing a 16:9 image. I know the 4:3 ratio screen is not ideal, but I could not pass up on the price.

This PJ has an offset of ~7" from center of lens to the bottom/top of the picture. Another optional arrangement would be to mount it from a shelf on the back wall about 70" above the floor and invert it.

Any thoughts?
