Here's a video which doesn't seem to mesh well with some of Ethan's findings: youtu.be/akiWq97dSBASpecifically his use, and type, of diffusers at early reflection points, his treatment of the front wall and putting thin, flush-mounted absorption in the corners rather than bass traps. Also he's put diffusers in the rear corners and just one small curved diffuser behind the listening position. I liked his visual acoustics video but this seems a bit misleading. Just thought I'd put it here for critique. Thanks, -m

Yeah, that guy is pretty clueless. Those aren't even diffusers, they're "poly deflectors" as shown here: All About Diffusion--Ethan

With your example polycylindrical deflector, the curves are consecutive thus contributing to that "focusing" area. I remember seeing an image similar to this one: of a mix room that had cylindrical deflection on the left and right walls, but spaced both on the x and y axis, with absorption behind. Is that the type of application you would approve for these types of treatment? Thanks, -m

Poly "deflectors" make sense in large rooms like in that photo, and they're at least better than a flat wall. Everest shows them used in large recording studios too. But in a bedroom size space they are totally inappropriate IMO. And even in a larger room a real QRD is better.
