It was 1979. I was 4 years old, and my dad bought a new sound system. It was a quadraphonic, the ancient ancestor to modern surround sound. Anywho, it had 4 speakers, one in each corner of the living room. But the speakers were unique. Inside the speaker box was a series of colored lights, that would flash and reverberate to the rhythm of the music. It had red, blue, orange, green, and yellow lights. I vividly remember being hypnotized by the lights as my Muppet Movie 8-track played. Anyone else remember these kinds of speakers? I very much would like to find them again. I don't remember the brand name, nor have i even seen a pair on ebay.
