This paper describes the application of a general mathematical method to the identification of low-frequency loudspeaker systems. Third-order Volterra series is applied to match the measured harmonic distortion responses of three commercial low-frequency loudspeaker systems with simulation results. This allows to compute the non-linear parameters of the loudspeaker, used within standard physical models. The proposed approach can be used as a general method to define loudspeaker dynamic models, exploiting standard acoustic pressure measurements, instead of displacement variation.
