This 18 Gauge Speaker Cable from Belkin is made with precision-formulated polyethylene dielectric material for high accuracy and natural sound quality. Using advanced engineering methods and the highest-quality materials, PureAV Speaker Cables deliver the purest audio solution available. Ordinary speaker cables sacrifice performance by using lower-grade materials, including steel or low-purity copper conductors. This can result in signal loss that causes poor high-frequency reproduction, and sound that is not truly accurate. PureAV's speaker cables, however, maintain signal strength over longer distances.
18 gauge is the recommended minimum gauge cable for smooth sound reproduction. The longer the cable length and the larger the Amp, the heavier the gauge required.
