Abstract: 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.

Abstract: A free standing frame supports front, back, side, top and bottom panels in such a manner that the panels are free to move relative to each other. Speaker drivers are mounted to the front panel such that frontwave radiation therefrom is allowed to project outwardly. Rear wave radiation is, however, contained within the enclosure formed by the panels. Deflection of the panels as a result of impinging backwave energy dissipates the backwave without producing "ringing" or other resonant effects.
