The Siren Speaker Cable applies the design priorities of Evidence Audio to a cable that can handle the demands of an amplified signal without adding distortion through strand interaction.While line-level cables can avoid the smearing caused by skin effect using a 20-awg conductor, a single 20-awg conductor does not offer enough cross-sectional area to keep the wattage of your signal from turning into heat. The solution is to use three audio optimized conductors for positive, and three for negative in a helical array to lower resistance and provide ample dampening between an amplifier and the speaker drivers.The helical array provides a twisted-pair geometry balancing inductance and capacitance for a very dynamic sound, and the open-core design further spaces the conductors from each other to greatly reduce any magnetic interaction between them.Our proprietary high-purity IGL copper conductors exceed IACS conductivity standards for annealed copper, producing distortion-free midrange and high frequencies.Solid-core conductors eliminate the negative effects of strand interaction on the audio signal.Six individually insulated 20 awg conductors keep skin-effect distortions outside of the audible spectrum.Our open-core design provides twisted-pair geometry with spacing between poles for reduced magnetic interaction, delivering dynamic and dimensional sound.Polypropylene insulation holds conductors rigid to minimize electro-magnetic modulation of the conductors.
