Thought I'd share this with you:

Inexpensive but Effective QRD Diffusors Overview QRD Diffusors (known within the RPG brand as Skyline Diffusors) available commercially are quite expensive, but much cheaper versions can be built that perform just as well acoustically. Because of their structural complexity, they're generally made of molded plastic when you buy them off-the-shelf, because that's much easier to construct than hand-building each one out of something more substantial. Unfortunately, the fact that they're hollow tends to make them not too effective below about 800 hZ. Some manufacturers recommend stuffing them with FiberGlas, but that really only makes them more absorptive at the lower frequencies, not reflective. The only way to make them truly effective as diffusors is to make them out of wood.

Found this site while looking for "skyline" diffuser. Pro grade ones (plastic) run about $200 - $400 for 2x 24x24x2 panels.

This one, can be made out of real wood, providing actual targeted FREQUENCY diffusing - all for under $30 (depending on material costs).
