"particularly compared to if it went up instead of down."
Quite true! In fact the ATC-40's at work have a good size notch in the response up high but what you hear is not the notch but the sparkle of the hf driver as the response resumes above the notch.
for sure, this is NOT what one wants for mixing a recording, that is ideally neutral and flat.
Keep an eye out for a set of Klipple measurements for that speaker, those are becoming mainstream popular. Those show "where the sound goes" over the sphere quite well and doesn't require a chamber.
I use it even for crossovers some times, take the average anechoic mag & phase response over say a 10 degree or 20 degree cone on axis instead of one point.
