Any idea for this horn tweeter?

On xsim this is about to be a huge nightmare. Measured with umik-1, one meter far field. The woofers and mid are down 30dbspl compared to this one.

Wait, that means the woofer and mid have a sensitivity of like 65 dB?!? That makes no sense.
- What horn and driver is this? (Manufacturer/model number?)
- Looks like a power response falloff: is it a constant directivity horn? Which then should show a dropoff like that.
- But I can't imagine why it then drops like a stone above 10k
- The twin impedance peaks yes really maybe not possible to compensate for. But some fiddling maybe knock the peaks down I'd hope. The peak is not much % huger than the low line.
