There is a thread on the Gearslutz site where Jens Eklund (who makes EPS diffusers) posted some graphs showing that they need to be paint to work best.
I found this out personally, having used some unpainted QRDs for a while before painting them. It makes a difference. Check out page 8 on the "first diy diffuser build" sticky on the Audio Circle Acoustics section (my moniker is jk@home there), on how I painted them with foam brushes. I use three across the front wall, and have posted them here before.
As far as corner diffusers, I drilled up some diy BAD panels and placed them on my back bass trap, out of the reflect free zone. Pic above. The idea is to have the speaker output hit the BADs, then forward to the QRDs on the front wall, then to the listening position.
