I might be able to help.
I have the .zma on hand, but what .frd do you have in mind?
Send me a pm and we can discuss further what you need.

I wonder why you'd need to model it at all, since Troels Gravesen has done most of the heavy lifting already:
Compact-Studio-Monitor
The 00 actually looks easier than the K00 he used.
Once you have defined the bass filter, the tweeter just falls into place:
Here at 3kHz.

Frankly, i've got no idea what Im doing.. Trying to make a crossover for my 18W8545 + D2905/97000 by modifying his Amish build for the enclosure I want to use.
The crossover tutorial said to gather FRD and ZMA files, so I was planning to draw up his filter, load files and figure it out from there 🙂

Thanks. Ill PM you 🙂
What you need is a little free program that will trace the graphs for you, like this: FPGraphTracer : fprawn labs
Sometimes if the multitude of lines confuses the program, it helps to copy it to MS Paint and zoom in and erase some of the off-axis or even graph grid lines you don't want to copy before you paste it into the tracing program.
See post #7 in this thread for some more info. And maybe give that whole thread a thorough read too.

Thanks for your comment. My main goal here is to learn from the process, so I'm getting more and more curious the more I think about your post.
Can you elaborate the process you are thinking about a little more? If understand what you are saying, I could use the pictured graph to design the bass-part of the crossover, and then add the tweeter from there. Is that correct? Sound really interesting!
TIA
