Default ATC SM75-150s x-over design help?

I'm new to this forum. I was browsing through the internet and suddenly get to this forum.

It's a long story of how could I have that driver with me. Anyway, anyone who has been using them can show me the diagram of their passive x over? What would be suitable for them and what kind of passive type?

the SM75-150s that I have is a 4 ohm version one. would it be hard for the tweets to match them when building passive.

Sorry for the lacking of knowledge about the passive, because I used to play all active....

Thanks a lot

And I was actually trying to have those mid run with focal woofer or sub. Why do I try to use them because simply it is one of a few drivers that is available to sell down in my country.

I don't have volt, atc or flex unit down in my country. I would need to ship them to my place. And with all the regulation, the price can go to doouble or more.

The driver that I can get would be :

Wow, sorry it got cut in the middle, I pressed the wrong button.

The driver that I was thinking are:
1. Audiom 13 WX
2. Audiom 15 WX

Has anyone have experienced with this driver? Would it go as good as the freq respose curve said? Will it integrate with the mid just fine (around 300 - 400 hz).

sorry for asking this, because I think that a driver can have a great fr response but it might sound different. And I'm not so knowledgeable about this.

It is my first diy project. And it doesn't mean that I want to go all out on my first attempt with pricy drivers. But this atc sm 75-150s 4 ohm and the tweeter are the drivers that I already have. It's been laying around unused for so long. Then why don't I just try to use them for my own speaker set at home?

Can anyone help me to give me some insight?

Thanks a lot,
