Tracking Changes In Linear Loudspeaker Parameters with Current Feedback

Document Thumbnail

This paper explains how, that if the total moving mass of a loudspeaker can be known in advance, all of the remaining basic linear loudspeaker parameters can be determined using only current feedback. This is explained at a theoretical and practical level. Frequency- and time-domain algorithms for tracking the parameters are presented. Examples of the tracking performance of an adaptive algorithm operating with a real music signal on an actual loudspeaker are shown.
