I'm having issues decrypting your post. If you could please expand on you idea for me.
Could I calculate a regular rectangular box for the double frequency ( 90 Hz ) then split or double it to get right frequency ( 45 Hz ) for my build? I'm however not sure how to accurately calculate the size of the holes that way.
