DIY QRD diffuser - pictures

This is a beta version of diffuser
I wanted to know if I'am able to build it myself.
After some rehearsal of the sound reflected from this diffuser vs plain wall..
There's no way back... I will make more of them.
I would like to cover entire wall behind my mixing position.

So my question is:
How to calculate best QRD design frequency for my room.
Should design frequency be connected with my room dimension modes?
Or is it ok to improvise here with the design?

cheers

One thing you where smart to do was to not put the last frame piece on until the end. When cutting by hand it is almost impossible to cut all the pieces 100% correct and have them fit without gaps. Gaps are a bad thing. When we build ours we use a C&C to cut all wood and grooves for it to fit. Basically good job for building by hand.
