ABSTRACT:
The present invention is an improved two-channel, four loudspeaker-component enhanced stereophonic system which includes a pair of front loudspeaker systems, a pair of rear loudspeaker systems and a pair of speaker enclosures into each of which one of the front loudspeaker systems and one of the rear loudspeaker systems are placed. The enhanced stereophonic system also includes two electronic matrix networks which interconnect the input terminals of each front loudspeaker system to the left and right channel amplifier output terminals, respectively, and which also interconnect the positive input terminal of each rear loudspeaker system to the left and right channel positive amplifier output terminals, respectively. The electronic matrix networks include a first high-pass filter and a second high-pass filter each of which has an input terminal and an output terminal. The input terminal of the first high-pass filter is interconnected to the left channel positive amplifier output terminal. The output terminal of the first high-pass filter is interconnected to the negative input terminal of the second rear loudspeaker system. The input terminal of the second high-pass filter is interconnected to the right channel positive amplifier output terminal. The output terminal of the second high-pass filter is interconnected to the negative input terminal of the first rear loudspeaker system. Each electronic matrix network also includes a resistive attenuation circuit whereby the output levels of the rear loudspeaker systems may be adjusted.
