AB  - A time-domain method for measuring the parameters of linear models of loudspeaker drivers is described. The loudspeaker is excited by a low-pass filtered square-wave voltage or current input. In addition to voltage and current, the cone displacement is measured and recorded by a personal computer. From these data the parameters are estimated by system identification techniques, in particular the least-squares and the instrumental-variable algorithms. Application of the method on a number of loudspeakers, as well as on known simulated models, indicates that it is both fast and accurate.
