Okay, if this is so, then why does the simulation for the slot frequency response show the typical low-pass behavior of a Helmholtz resonator? Just like the impedance response (in attenuated form).

I would say that even with damping material, the effect shown in the simulation cannot be suppressed.
Is the effect undesirable or does it not exist in your eyes? The resonance at 200Hz can't be a cabinet resonance, since it was only 0.28 x 0.25 x 0.1 m in the simulation.
If no Helmholtz resonator is involved, then the 8C should not show a typical delayed resonator decay (with possible harmonics) in the 200-400Hz range.
Possible cabinet resonances of the midrange cabinet should be significantly higher in frequency, due to the small dimensions.

With Klippel data, can a single impulse response be exported as a 16-bit .wav file, for example?
Then one could have a closer look at the decay behavior.
