The depth of the RPG design is 6 3/8 inches. They claim a diffusion coefficient of .71 at 125Hz. I don't know what that means, but the diffusion coefficient they claim for the entire specified frequency range is not too distant (I guess) from the .71 figure. If it would take more than 7" to get lower than 500Hz, is RPG fudging the specs? Are they measuring an irrelevant factor? Perhaps you don't share their definition of effective wave-breakup?

It's very curious. See my post below comparing RPG with the online diffuser calculator, for additional confusion.

Thanks for the slice angle advice, Jon. Done carefully, that would look really sweet. I was also thinking of using different colors of paint to add a pointilist desgin of some sort to the diffusors. If I knew how, I would cheese out completely and effect two eyes that follow you around the room!

May the bridges we burn light our way....
