Those look pretty damn good aesthetically, something like that is kinda what my buddy was looking for, except in walnut.
He's now toying with the idea of gutting his whole room and starting over. Keep the drop ceiling and replacing the thin tiles he's got with 2" thick absorption tiles, and building out false walls with the appropriate mixture of absorption and diffusion.
Any information on the design, what frequencies are they optimized for, are they a prime based QRD? I've been trying to read up on diffusion and room treatment and it's a lot to take in.
According to the scientific experts in this field, good sound starts with good speakers. And a normal living room is fine for the highest sound reproduction possible.

May I correct that? Get the 3d edition instead. And normal living rooms are certainly not perfect listening rooms. Simple test, get your gear outside, removed at least 5m from any walls (as well as your ears) and listen.
Walnut was a consideration. More costly but would be very attractive.
In my stereo room, I'm thinking about building new walls in front of the existing walls to accommodate treatments.
The piano rooms ceiling perimeter has absorption covered with fabric. There's a skylight, the remaining space holds 42 diffusers.. I used the calculator here Calculate Quadratic Residue Diffusor ( given size )
Made small adjustments to the number of wells for different size boxes and maintained a consistent aesthetic

that's the big line of BS i've encountered in a while...a crap acoustic environment can destroy the best loudspeaker out there no problem.
