Fostex FT17H - hurts my ears
I can't promise that it will sound good, and with ribbon tweeters you can usually not cross as low as with dome tweeters. Safe bet qould be 3000Hz, maybe 2300Hz. It loos more sensitive than your Fostex cone driver, so maybe add a resistor or biamp. Consider that some ribbon tweeters already have a coil in the form of a transformer My Raal has 2mH in its transformer, so I need to think about that when making the crossover. If I add a coil, I can't just think about that coil. I wou°d make the passive crossiver as low and as simple as possible and then experiment with a digital filter like minidsp to find the sweetspot, and then look at the B4 active analog filter when it comes out eventually.

That was high. I bet he could cross it lower as well.

There's a lot of good advice here, a steeper slope would go a long way, and it likely wants more padding, and the midwoof should have some shaping. The midwoof may be part of what's bothering your ears, high-bandwidth minimal XO drivers with whizzers can shred your ears, and moreso at higher level.

I get the appeal of a minimalist widerange/supertweeter setup, but the more experienced I've become the more I appreciate a well designed multiway system with good XOs. In this case, a proper horn/waveguide would be a much better solution. You can use something like the "Econowave" project as a start point.
