AB  - A new method for the estimation of the nonlinear modeling parameters of a electrodynamic loudspeaker is presented. Measurements of time-domain voice coil displacement are compared with the predicted displacement from a modeled loudspeaker. An optimizer adjusts the coefficients of the functions describing the nonlinear parameters. Loudspeaker nonlinear parameters are obtained through minimization of error between the measurements and the modeled response. The resulting nonlinear model yields good agreement with measured data over a broad frequency and amplitude range.
