Use of RPG's SKYLINE diffuser

I have four of them, behind the listening position, and two homemade ones on the front wall between the speakers. Both help the sound a lot. Read F. Alton Everest, "Sound Studio Construction on a Budget" for examples of where he places them. Check back with me if you want DIY instructions for Skylines, Omniffusors, 734 QRD diffusors. (But only if you have a table waw--impossible without.)

They received a "Golden Ear" award from TAS in January 2000, where there is reference to an earlier review. I use two behind my listening chair, to good effect.

Tom, I am very much interested in the DIY of RPG Diffusor. Please advice.
