Here's an idea. Looking more at comfort here, that design looks killer on the back.
Make it more like a lounge instead of sitdown..extend your seating so its more like your playing on your back.
Have the CP across the opening in the center.
Have your screen up more and not enclosed at angled 45 degrees down towards the players.
Drop the loungers down a few inches into the enclosure, put speakers on both sides and a sub in the back area, its already a good box, so you can feel the game.
I suck at drawing so I cant sketch this out like I see it.
It would be something I've never seen before......
