In the mid ’70s Ray Kimber worked at a sound and lighting company in Los Angeles. The first big discotheques were being installed at that time. Traditionally sound and lighting systems were not installed right next to each other, nor did lighting systems ever have such an array of noise generating fixtures, such as strobes and other flashing and dimmable lights. But in a discotheque the lights and speakers are installed next to each other. The speaker cable was acting as an antenna array and bringing noise from the lights into the sound system.
Over the years Ray would continue to test various metals as conductors, assorted manufacturing protocols, assorted stranding sizes, different twist lengths and insulation, as well as methods for adhering insulation to cable. All the time improving, modifying, and expanding upon his original cable concept and design.
