Different Helmholtz Slat Sizes

I understand the basics of a helmholtz array wall with one size on slats/slots and I can make calculations on that.

But in some studios I see helmholtz array walls with different sizes on both slats and slots. Is there any expert here that can explain how this works in more detail? (more than one cf obviously)

When every slat has a different slot on each side and every slot a different sized slat, how does this affect my calculations?

Basic helmholtz knowledge maybe, but couldn't find any good explanation online.

Hope someone understand what I mean and can elaborate a little further.

Best, M
