Coming from a DIY background and being a musician, I know that money can be tight. This was my solution to the high cost of acoustic treatments. One by one, others have found out about my diffusers and some have requested that I make some for them.
I have a small buzz going on about me here in the states, I thought I'd share some DIY ingenuity. The way they are made is simple enough, from already available equations, so that's nothing really special. Some hange the name "skyline clone" on them which isn't exactly true. As the prime number theory I use is slightly different.
