Or possibly some specs for the Xenon tweeters?
I have been trying to backward engineer the Xover for a pair of Xenon 6.5's to find their original crossover setting & slope, but its too complex for me to figure out & looks nothing like the typical calculators Ive found online.
Here is what I have uncovered.

This is the overall circuit for the tweeter from the main Xover input. I have eliminated the phase switch, "A-pillar" switch, and HF Boost switch circuits, because with them off this is what the full path through the crossover looks like for the tweeter.
