Title: Unitary panel multiple frequency range speaker system

Abstract: A speaker enclosure is provided with an elongated vertically oriented flat panel having a plurality of vertically spaced speaker openings and a sound port positioned near the upper end of the panel. A pair of stereo related signals are provided to the speaker enclosure, each signal being coupled to a respective crossover network. A first combination of speakers, including a tweeter, mid-range, and woofer is coupled to a first crossover network and provides reproducibility of a first frequency range of audible sounds, and a second crossover network is coupled to a second combination of speakers, including a tweeter and a woofer, to provide a second frequency range of audible sounds which is narrower than said first range. The first and second ranges and crossover frequencies are selected to enhance a first music pattern, such as "jazz," and the second frequency range and crossover frequency network is selected to enhance a second music pattern, such as "rock." The channels may be selected for playing separately for enhancing their respective music patterns or may be selected to play simultaneously to enhance the overlapping frequencies in the frequency ranges.
