So, what do you guys think about the model D diffuser BRM linked ? Sure looks cool! Will it perform as well as a skyline diffusor. I'm guessing that's its closest cousin.

Another thing to remember about diffusers is they are most effective when they are placed a minimum of 6-8 feet from the listening position. I was going to get some diffusers to put on the wall behind my listening chair but decided against it after researching them. My chair is only 3-4 feet from the rear wall so I went with absorption instead.
Dave,Well, theres no accounting for tastes! I like them. But I can see how they would not work in some environments. If your home or listening environment is filled with mauve colored furniture, lace doilies and ruffled curtains around the room, then yeah, this look would not be welcome in there. BUT if you have a more modern look with solid, bold or sophisticated colors with corresponding modern or even mid-centurey modern furniture, these "ripple pool" panels hanging on the wall, like in the pics, would be quite cool looking, IMO... But again, if your house looks like my Grandmothers did, they would be out of place.
A quick scan of the model D diffuser makes me wonder:- undefined "thermoplastic" material (can a 1 pound per square foot material really be acoustically opaque enough to reflect sound?) seriously doubt it- the stated bandwidth is 599 - 16,000 Hz yet the "true diffuse" frequencies is specified as a more believable 1195 - 5975 Hz, what does any of this really mean? no industry standard test results- if you look at the panel the nominal depth provides a variation of roughly 1 inch which equates to the wavelength of 13,000 Hz, so the geometry would indicate maximum effectiveness around that frequency- to be effective diffusers must have a depth that matches the sound wave length (sound travels at 13,000 inches per second through air, so a 1000 Hz sound wave is 13 inches long) which is why diffusors have practical limits and you don't see diffusers rated to say 100 Hz and why good diffusers must have a wide variety of random depths- the skyline diffuser should be vastly superior (surely acoustically opaque, better performance as being designed to industry standard quadratic variations for much improved function, and can be DIY'd), but heavy in large sheets. I looked into building my own, pre-painting the wooden blocks in various colors (each depth the same color), but I'm no carpenter.
