Yes, but not grotesque like some others.
Today i measured the tweeter. That took longer then anticipated so i will measure the woofer tomorrow. i got a rather detailed analysis though.
Here some pictures from the setup.

Here are the frequency response measurements on the Satori tweeter on the 1.2m x 1.2m baffle. The bumps in the response under 3kHz are an artifact of the baffle.
It disappears in the near field response.
The on- and off-axis response was measured in 50cm and the near field response in 10cm.
The measurements where taken at 0, 10, 20, 30 and 45.

Here are the near field measurements at 0, 15 and 45.
The second measurement is in the near field at 45 and 60. The characteristic notch is highest on 45 and shifts down in frequency and depth at 60. That is a geometric artifact because parts of the membrane reach the microphone early and some later from the far side.

Here is harmonic distortion, second and third, at medium volume and high volume.
The high volume was rather challenging loud on my ears.
Measurements like this are hard to interpret because a comparison can only being made when a competing tweeter is measured at the same volume and distance.
This measurement was also taken in the near field.

Here is a multi tone test. 31 frequencies spread in such a way that they do not inter modulate much with themselves. This test is also know as Spectral Contamination.
The first test is with the driving signal and the other shows the multitones notched out so that is a so called Belcher Test.

Here is a single tone spectrum, high volume, at 1.8kHz and 4kHz.
THD in both cases is around 0.55%.
