An Empirical Model for Loudspeaker Motor Impedance
Julian R. Wright · Journal of the Audio Engineering Society · 1990
The high-frequency electrical impedance characteristics of a moving-coil loudspeaker deviate significantly from those of the traditional series resistance-inductance model of the voice coil. The deviation is attributed to eddy current effects within the magnetic pole structure. An accurate model of loudspeaker motor impedance is described here
