Cables so good you only need one instead of five.

When photographing products for advertisements the art director has a couple of choices; photograph the product as it is really used, or photograph it as it looks best.

In this case, although there is room to attach five speakers; two front, one centre, and two surround, the photograph only shows one speaker attached.

Perhaps the speaker cables are so expensive that I won't be able to afford to buy five sets all at once. Or they're so good that I won't need to attach the other four speakers. At least the polarity of the cable is right, assuming that the other end is attached correctly to the speaker.
