An improved loudspeaker system comprises an active crossover network for dividing the signal energy of an input audio signal into at least first and second frequency ranges separated by at least one frequency band, and at least a third frequency range including at least a part of the frequency band. The number of power amplifiers normally associated with a typical, similar powered loudspeaker system is reduced by combining the signal energy of the audio signal with at least the first and second frequency ranges so as to produce a first component signal and utilizing the signal energy in the third frequency range to form at least, in part, a second component signal. The system also comprises amplification means for independently amplifying the first component signal and the second component signal; means, including a passive crossover network, for dividing the signal energy of the amplified component signals into at least three output signals respectively including the signal energy in the three frequency ranges; and a plurality of speaker drivers connected, respectively, to be driven by the respective output signals.
