Have you calculated what you would need? On average, a 12,000 BTU unit cools and heats about 500 sq. ft. efficiently. It goes up from there, so based on the size of your room, you may need only one appropriately sized. Can you place the angles of the front left and right speakers from the head of the front row on your drawing?
I like the idea of diffusors in the rear area. As you can see in the picture in previous post, I have diffussor on both sizes, but I think I can get more benefits if I add a couple on the rear wall.
Currently I have a small room in a side (see the post above) along with the rack there is an access door.
I´ve thought about to move the projector in the "service room", but I haven´t check if in that distance the image keep the size (150") an PQ. I have to review.
I live in México, Veracruz more precise, and here in summer the temperature reach the 40-43°C (104-109°F), so the capacity of the Minisplit must be bigger. For my application I have 2 units of 18000 BTU.
So far very good outcome in period of high temperature.
Find attached the angles. But remember that the size of the room may undergo some change and the position of the speakers may change even.
