It will have a 130" AT screen and a projector. 9' ceilings. First row of seats will be about 11' from the screen. As far as budget I don't really know but I'd like to keep it around $1-2K for speakers.
How many rows are you contemplating? The reason I ask is that you really should have one set of side surround speakers for each row for the best sound spread (just like in a commercial theater). This is also so you're wired and at least somewhat ready for the new object-oriented audio formats coming down the pike. Each speaker can be individually addressed unlike the fixed channel based formats of today. DTS and Dolby are squaring off again (with MDA or Atmos)... either way... things should sound awesome!
I would highly recommend at least
two 15" ported subs for that size room. Check out the Rythmik FV15HP. You won't regret pushing your budget for these bad boys. Get one and then go for another (just make sure to wire for the future).
Ascend Acoustics is running a holiday sale right now on their site. You could go with a 7.1 setup of three identical, vertical CMT-340's SE monitors (make sure you don't go with a horizontal center when using an AT screen) and as many pairs of HTM-200's to cover however many rows you have planned and then another single pair for the back surround. Great bang for the buck. They also have a partnership with Rythmik where you get a small discount if you purchase a sub or subs with Ascend speakers.
If you're still in the construction phase, do Google the DTS Multi-Dimensional Audio (MDA) and Dolby Atmos white papers to get an idea of pre-wiring for mirrored overhead surrounds (they mirror the locations of the wall mounted surrounds on the ceiling) and front wide L/R screen speakers (as well as possible surround speaker subwoofers). Cheap insurance for the future. They'll also give you an idea of how to aim your direct radiating, wall mounted surround speakers for the best experience.
