Brilliant teaching aid/tool ... we need more of these to demystify a lot of tweaks that work but can be hard to understand ...

Just finished building these for myself. They seem to work quite effectively placed on the front wall behind my speakers.

I too would very much like to know where you got the pattern for these! OR if you just randomized the dowel rods?

Here is a post I made regarding the AGS technology or  Acoustic Grove System diffusors:

And here is the original post from RMAF that clued me in to this type of diffusion:

I like the look. They would fit with my room and would very much like to know if there are plans or math out there for this type of diffusion.

Thanks
