A speaker will have the equivalent of leakage reactance. Ideally, the air
driven by the voice cone will generate an acoustic wave who's load shows up
as resistance on the voice coil terminals. But speakers are not ideal.
For the crossover networks, it probably depends upon how implemented. Again,
an ideal crossover will look resistive.
