Abstract: The present disclosure relates to a system for and method of stereophonic widening in loudspeakers. The method includes the steps of: monitoring an amplifier state and/or loudspeaker state; generating an effect control signal in response to monitoring the amplifier state and/or a loudspeaker state; applying the effect control signal to an effect processor. The effect processor controls an amount of stereophonic widening based on the effect control signal.
