The right question to ask is if one could really hear the differences in .05 mph changes
Electricity and magnetism are inseparable. Inductors are nothing but a piece of wire coiled to accumulate the magnetic forces generated by the electricity following in the wire into a single magnetic field (common poles). This accumulated magnetic field is the heart of an inductor.
The inductors in the high pass and low pass sections of the crossover work over a different frequency ranges. When the magnetic field one inductor interferes with the magnetic field of another, it creates unintended effects on the charge and discharge rates of the inductor. These charge and discharge cycles are the frequencies passing thru the inductor.
The author of that study connected the inductors in series to measure the overall effect of EM interference. It doesn’t say what the effect on the inductors is when both are operating at different frequency ranges are of different strengths.
