Previous circuit models of dynamic moving-coil transducers that incorporated “semi-inductors” need to be extended in order to cover those cases that failed to adequately predict performance. The improved model takes into account semi-inductance, the effects of AC shorting devices, and the impact of frequency-dependent loss in the suspensions. As shown by the good agreement between the models and measurements, only a few additional components need be added to the model. This represents a more detailed physical understanding of loudspeaker behavior.
