Compared to commonplace 16-gauge wire, AudioQuest's X2 speaker cable reduces resistance over longer runs, so your high-quality components and speakers will get the cleanest, most accurate signal possible. As a general rule, the lower the gauge, the thicker the wire, and the better its capacity to pass amplified audio signal.
AudioQuest's cable designs come from years of in-house research and careful engineering. Their X2 speaker cables use a special semi-solid concentric arrangement that keeps the bundled strands in the same position throughout the length of the cable. The signal encounters less potentially damaging interactions and shifts in magnetic environment, resulting in sound that's clearer and more dynamic. The conductors are made of long-grain copper to ensure efficient signal transfer with minimal loss.
