Inductance levels are less about the peaks, and more about having an overall consistent level.
In the video posted this morning, the tweeter response was closer to 16 ohms, while the woofer was closer to 8. And having that mismatch can cause issues with phase rotation and having that much resistance in-line makes it harder to drive with certain amps, esp those only rated for 4/8ohm loads.
So by reducing inline resistance, and using a resistor in shunt, it brings down the overall impedence load the amplifier sees for that driver without raising the overall impedence.
