Thank you for providing. Only my humble opinion. The F4 Phantom jet has such strange angles to correct stability anomalies as described by a friend (aeronautical engineer Boeing). Everything a correction of flawed initial design.
I submit a trapezoid shaped room with rising ceiling, front and back walls red brick would negate the need for a lot of this room treatment. And, if you really want to get crazy, put it all subterranean to eliminate external intrusive sound.
Obviously, I’ve not heard this room, so could be quite wrong.
