Comparison of Dynamic Driver Current Feedback Methods

Authors: Backman, Juha

AES Convention 145 · Paper 10059 · October 2018

Abstract

Current feedback is a versatile method of modifying the behavior of a loudspeaker driver, with opportunity for linearization and matching the driver to the enclosure design targets, but depending on the chosen approach a potential risk of increasing the effects of either voice coil impedance variation or driver mechanical parameter nonlinearity. This work compares using a nonlinear simulation model various forms of current feedback, including current drive, finite positive or negative amplifier resistances, and negative resistance combined with a reactance.
