Ok, but there is also the cap across the LF driver also rolling it off at a design crossover F.
That presents a falling impedance to the inductor output side while it's series impedance is increasing. What ever inductance related distortion, is always at multiple higher frequencies where the capacitor's impedance is even lower.
Have you measured a filter under static R load with an open frame inductor like that vs an air core of the same Rdc? If so what did you observe?
