If I may offer some advice.

Identify where the seating needs to go for best audio performance first. From there, that will tell you the screen size. To move the seating around to 'force' the viewing angles to be right at the expense of audio performance is defeating 1/2 of the movie experience.

You can do whatever you want in terms of treatments and EQ but if you're sitting in a really bad place in the room, nothing is going to fix that short of moving.
