The Canare 11 AWG 4S11 Bi-Wire Speaker Cable with Four Spade to Four Spade (30') is designed for bi-amping electronic equipment with multiple spade-style inputs and outputs, such as an amplifier to hi-fidelity speakers. The cable utilizes Canare's Starquad low-capacitance stranded annealed copper wiring scheme that significantly reduces electro-magnetic interference. The connections are handcrafted with true silver solder and audiophile-grade gold-plated spades. The cable features a polyethylene dielectric insulator that provides a consistent frequency response over long cable runs and will remain flexible even at sub-zero temperatures.
