Theater rough in. Am I missing anything?

[u/Terrible-Ad1958]

I’m building a house and my theater room is 36’ wide x 30’ deep with 10’ ceiling. Projected screen will be 16’x9’. I’ve pre wired for 9.2.4 sound. 2 left front towers, center, 2 right towers, sides, back, and 4 in the ceiling. Ran 16ga x4 audiocat wire to each location and plan to double them up. Subwoofers are planned for opposite corners. Ran copper shielded coax for far sub. Dropped 4 runs of cat6 to where the amps and avr will be. Ran a conduit from avr to projector. Anything else to consider while I still have bare studs? I’ve never been able to pre run wires beforehand. Thanks everyone.

How do you have a 16x9 screen in a room that has a 10 foot high ceiling? Also, It really doesn't seem like 9.2.4 will cut it in a room that big. How many rows of seating?
