In recent posts on VituixCAD thread on diyaudio, Kimmosto has outlined a procedure for passive crossover emulation using VituixCAD and EQAPO softwares. An FM had generously captured the ideas and have explained it in the attached document (initial release) and made it available publicly. I will update incase he updates the document. Original thread and posts here:

The idea is to emulate what a particular passive crossover (filter) IIR transfer function does by emulating it using FIR filters. This will help one understand the implications of the filter on tonal balance and adjust crossover settings. The advantage is that all the crossover tweaking via passive components can be done in software and heard before going and buying parts. Off course there are a few caveats and it is mentioned in the attached document. One will need VituixCAD, EQAPO, a multichannel soundcard, amplifer(s) for using this feature/functionality.
I personally feel that this is an incredibly useful functionality to really understand and learn the impact of different crossovers on a speaker during development. And finally when one is satisfied with emulation results, one can test with real caps, inductors and resistors to build the crossover network according to the finalised configuration.
Hope someone will find it as useful as it is to me or more
Thanks

No. Few library blocks are available for passive and active 2- and 3-ways, and optimizer supports iteration of block attributes suct as XO frequency and Q factor too. Any project can be used as starting point/template for other project. Ideal flat axial response can be created for active FIR...
