Abstract
A novel method for the measurement of the Thiele-Small small-signal parameters of a moving-coil electromagnetic transducer driver is disclosed. The technique is based on a time domain analysis of the transient response of a loudspeaker voice coil circuit to a current step of excitation. By sampling the damped sinusoidal transient generated by such an excitation, the loud-speaker parameters can be calculated from a linear predictive analysis of the recorded data.
