LOUDSPEAKER SYSTEM UTILIZING AN EQUALIZER CIRCUIT Abstract of the Disclosure A loudspeaker system includes a low-frequency driver and a high-frequency driver which are connected to a crossover network. The crossover network includes an inductor in series with the low-frequency driver for attenuating high-frequency signals at the crossover frequency and a capacitor in series with the high- frequency driver for attenuating low-frequency signals at the crossover frequency. An equalizer circuit connects between the high- and low-frequency drivers and operates to dampen resonant ringing which is otherwise produced. The equalizer circuit preferably comprises a series LRC circuit having a resonant frequency and a Q factor equal to the resonant frequency and Q factor of the circuit formed by the crossover network and drivers. The equalizer circuit is particularly suited for application in a disclosed loudspeaker system which utilizes a high inductance crossover inductor to enhance system bass response without sacrificing clarity.
