Bi-Wire Speaker Cable

Bi-wiring requires that four conductors be run for each speaker. Two conductors provide the positive and negative for the mid and low frequencies, and another two conductors provide the positive and negative for the high frequencies. At the amplifier side, the two positive cables are connected together to the positive post on the amplifier and the two negative cables are connected together to the negative post. At the speaker side, the cables sending the mid and low frequencies are connected to the bottom pair of binding posts and the highest frequencies are connected to the top pair.

The only real benefit, aside from doubling the gauge of your cable, is achieved when different types of cable are used to maximize the subtle differences in the way low and high frequency signals are transferred from amplifier to speaker.

With our bi-wire cable, the highest frequencies travel across 252 indivdual strands of silver-plated, oxygen free copper with a total thickness of 14 gauge. Silver is a better conductor than copper, especially in the high frequency range. Some high-end cable manufactures use pure silver instead of silver-plated copper. While this is better than silver-plating, it is also about five times the price. And because electrons tend to flow along the surface of the cable, silver-plating yields the best performance to cost ratio.

For the mid and low frequencies, our bi-wire cable transfers the low and mid frequencies along a thick, 11 gauge cable that consists of 490 individual strands of 99.99% oxygen-free copper.

Bi-amping (as opposed to bi-wiring) requires one amplifier for the mid and low frequencies and a separate amplifier for the high frequencies. This type of connection achieves an even higher degree of separation but is also a much more expensive option. Only the most expensive home theater recievers include the ability to bi-amp. That said, some more affordable 7.1 receivers allow you to utilize a 5.1 setup and convert the sixth and seventh channel for use with bi-amping the front left and right speakers.
