Abstract
An equalizing circuit, for compensating frequency response perturbations in a loudspeaker caused by a recessed mounting of the loudspeaker, includes an input for receiving an audio signal, a peaking network coupled to the input for augmenting the audio signal in a first frequency range, a dipping network also coupled to the input for attenuating the audio signal in a second frequency range, and a combiner for combining an output of the peaking network to an output of the dipping network, an output of the combiner carrying a compensated audio signal for application to the loudspeaker.
