Yes. As I said before, without changing the mid filter, if all you did is move down the tweeter level, then you altered the crossover frequency to a little bit higher. How much depends on some things, and I suspect it is a small amount. Remember that the crossover point is not defined by the tweeter filter alone, but it is a combination of the acoustic slopes (not the electrical ones) of both the mid LP and tweeter HP filters.

Lots of potential improvement on both the before and after graphs. As Allen suggested, it would be easier to see what's happening with mid and tweeter FR separated

I think the best idea is to buy a bunch of cheap 5 watt resistors and fine tune using REW as a guide . Don't worry about all the nonsense audio quality resistors affecting the sound . Once you have fine tune the sound to your liking then go ahead and spent hundreds on that negative inductive non capacitive non reflective super resistor that you fancy according to the resistance that you want.
