I have setup a projector that projects a picture onto my garage door (16 x 9). I then put an Arc in the center of the garage (hanging below the garage door opener). I added two Fives in the back corners and a Gen 3 Sub on the left wall near the rear corner. It already sounds awesome, but I am adding a Gen 3 sub to be on the right wall near the front corner (kitty corner).

I was a little worried that the Arc being close to the ceiling would sound bad, but it really sounds awesome (it is about 30” below the ceiling).

Probably don’t need it, but curious if adding two SL’s centered on the walls would enhance it or not (if you can add that many to the system).
