So I have built walls up until the point of the screenwall and I need to start making some final decisions. I did two newbie screenwall mockups in sketchup. What are your thoughts? I did go so far as to make sure the angles for the speakers are correct for the 7.1 setup (~24*) I don't have the sub and center placement figured out yet, or whether or not I would have a top header to the wall either. The screen options I "think" I have are

1.78:1 --> 100"

or 2.35:1 -->96"

The total available open space is ~8' with the side stands in there, total height is just over 7'.

The projector will be mounted about 11'-12' away. First row of seating is about the same.

I know there is concern with putting speakers in a boxed out portion of a "wall" as well, but I'd like it to have a clean look and I will be hiding some plumbing, which is the need for the colums.
Where it is now...

Thanks for any help you can give, I promise my build thread will start soon.

Considering that you appear width limited rather than height limited, I would recommend the larger 1.78:1 screen. I am not convinced you would be pleased with 1.78:1 material on a 2.35:1 screen of that size.
