sealed speakers for mid range. Where can I find out everything about it?

I'm studying the DIY audio scene, I'm reading a little about midrange.
Some people on the internet say that they treat the midrange as if it were a normal woofer in WinISD, whenever I made boxes for woofers and subwoofers it was always a recipe I found on the internet and currently I would like to learn how to do something more professional...
In addition to the T/S parameters, how can I know the frequency that I will put in the box, the QTC and the FSC in WinISD itself?
Is there somewhere I can study and read about?
