I'd like to make it mix friendly more than anything. I have a bunch of sweet rooms to record in, but no good room for mixing.
I'm currently building absorbers for bass because I already know it's an issue.
I was given 2 QRD diffusers that were built by students at our local conservatory.
They have 25 wells....

What's the deal?
I thought that it had to be prime numbers?
There are 25 1 inch wells 1/4 inch dividers and they are 5-3/4 inches deep.
Does the improper design effect (or is it affect?) the diffusion in a negative way?
I know it must be diffusing but it may be scattering things in a bad way.....I don't know.
Any help for the new guy is greatly appreciated.
