So, I am not a speaker-cable expert by any means, but I was taken aback by what one local store had rigged up for speaker cable. Not necessarily in a negative way, but something I never would have thought of, which was that they were using a single coaxial cable for each speaker. Needless to say, this struck me as quite odd. They had a gadget on each end... gosh i forget what they called it, but it took the rca connection, into a tiny box, and outputted on two short wires, R and B to the speaker terminals. I don't know what this contraption was, or how it worked, but it seemed quite strange to me. They said they used it all the time, in their installs, and everything, and that the little boxes at each end of the cable were only about ten bucks each. Has anyone else seen such a setup with coax cable? If so, how does it work, and how does it sound (assuming that not all speaker cables are totally equal[which, except for tiny wire I am skeptical of]). It would seem that a coax cable would not be designed for this use. Were they just using the inner conducter and the shield as the two conductors? Ideas? Are they nuts?
