A technique is described which enables profiles of transduction coefficient B1 versus cost position to be plotted for an assembled loudspeaker, with voice coil current as a parameter. The performance of a system comprising a prototype loudspeaker with extended center pole and compensating winding, combined with digital forward error correction is described. This system simulates a linear motor with very low distortion.
