@dameo182 First, where are you taking these measurements from? How far away and are these on the Tweeter axis, center on the baffle?
Next, after you answer those questions it would be best to take three measurements with the crossover unhooked. The first is the Tweeter centered on the Tweeter at Tweeter level 16 inches away. Then unhook your Tweeter and play just the PC 83 with the microphone in the exact same position. Finally take one last measurement of both of the drivers in parallel. Once you have those measurements, upload them here and I’ll help with the design.
