213 Speaker Cable

Speaker cables present a complex dilemma to the cable designer. They must be large enough to deliver high current peaks from the amplifier with minimal loss. However, merely increasing wire thickness will introduce a host of distortion-generating artifacts – most significantly, phase shift due to excessive skin-depth. In order to solve this problem in the most elegant manner possible, Empirical Design has developed an innovative conductor for our 213 speaker cable. High-purity copper strands are woven into a single-layer braid surrounding a Teflon tube core, thus forming a "virtual cylinder" with a net cross-sectional area equivalent to a 13 gauge wire. Since the wall thickness of the resulting tubular conductor is less than 1 millimeter, phase shift is eliminated across the entire audio frequency range, yet the conductor still possesses sufficient size to effectively transfer power from the amplifier to the loudspeakers. The Teflon insulated positive and negative leads are bonded together in a parallel geometry, preventing relative motion in order to stabilize cable reactance. The cored cylindrical conductor geometry is even maintained through the environmentally-sealed termination connectors; there are no loose strands to oxidize or break with long-term usage. 213 will continue to perform ideally year after year, coupling your amplifier to your loudspeakers with breathtaking clarity, precision, and responsiveness.
