Just pulled it up on my laptop.
Some physics to digest before biting the bait (video link below).
My front walls, with six P-17 diffusors covering 8.5’H x 9.5’W x 16”D of space, has a horizontal diffusion bandwidth of 242 - 3,385 Hz. The randomized non-correlation of the indirect sound from your speaker’s output is what’s critical in creating the illusion of deliciously precise and well-localized sonic events in a 3D soundstage.
What’s the diffusion bandwidth of the ZR Acoustics panel which you’re using?
