Abstract
In high-power operation the loudspeaker driver's voice coil gets heated up considerably. This causes an adverse change of the loudspeaker parameter Q( TS). Current drive offers a solution by removing electromagnetic damping. M otional feedback is one of the methods used to provide damping for systems of order 2. The authors extended these solutions to successfully include hi gher order systems.
