@ thanks for your response, but I am still wondering why is it called like that. I am asking you original meaning of "primitive root"

@@forthemaxandminmin152 It's a mathematical term. The Equation used to calculate the placements of the pieces uses "primitive roots" in its function. The name of the diffuser is from the equation used to create it.
Think of this as building a "lens" to carefully scatter all frequencies within its bandwidth. If you use a random layout you're almost guaranteed to have some frequencies that are focused instead of diffused, and the beaming effect will be even more obvious due to the other frequencies being well-managed. PRD & QRD are essentially fractal patterns that "look" the same at different scales, causing different wavelengths to interact with them in similar ways. If you get it wrong it will sound like parts of your "diffuser" are resonating at specific frequencies. Basically, if you're going to go to the trouble of building one then follow the math. I haven't heard of other fractals that work better so I'd stick with proven designs myself.
You can do random or make designs as you wish. the bit that matters is the ratios of size. so if you keep to the rations as in the lengths then you are fine. yes the point is to scatter as much as possible. thats a ratio game more that the pattern. for example the "Gotham N23 5″ Quadratic Diffusor" are not random! & would be classed as pro level.
Looks cool, I did a sound test in one of my rooms and the desk has very high early reflection comb filtering
Thanks:) How do you determine wells width? the calculator doesn't say anything about it?
Make it even. I did 1x1 you can do whatever dimensions you want as long as it's square
Thanks for your work! amazing!, I have a question for you. why is it called "primitive root" diffuser? any idea?
No problem, its the type of function that calculates the dispersion pattern :)

@ Thanks for your help what about QRD ??? any idea?
@@forthemaxandminmin152 "quadratric residue diffuser" it uses different shapes and a different forumula to achieve sound dispersion
Any idea what happens when you don’t use a specific grid layout? But just random sizes and layout…
I would think it would still work. It just wont have target frequencies i would think

how its heavy?
about 80lbs
