Abstract
A multimedia system includes at least a first pair of satellite loudspeakers for radiating left and right channel signals, the satellite loudspeakers having a first lower cutoff frequency. The loudspeaker system also includes a separate subwoofer having a first upper cutoff frequency. The first lower cutoff frequency is higher in frequency than the first upper cutoff frequency. The loudspeaker system also includes a center loudspeaker array. The center loudspeaker array radiates center channel signals, and also directionally radiates left and right channel signals in the frequency range between the first lower cutoff frequency and the first upper cutoff frequency. The multi-channel loudspeaker system may also incorporate additional satellite loudspeakers for reproduction of surround channel signals.
