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... In an attempt to solve the problem they encased the speaker cable in a steel conduit. This did help with the noise, but it also had the unintended result of lowering the fidelity of the audio. This happened because the steel conduit interacted with the magnetic field of the speaker cable... Ray had the idea of some counter-rotating sets of conductors to cancel the magnetic interaction effect, but then also surmised that the counter-rotating..
