The SAEC SPC-650 holds a special place in audio cable history as the world's first speaker cable to incorporate the revolutionary PC-Triple C conductor, developed through a collaboration with Furukawa Electric. This patented high-purity copper undergoes a unique continuous forging and drawing process that significantly reduces crystal grain boundaries (the impediments to signal transmission) by aligning the crystals continuously in the longitudinal direction. The result is exceptional electrical stability, high conductivity, ultra-low distortion, and reliable performance tailored for audio applications.
The cable utilizes a 2-core twisted structure with each conductor having a cross-sectional area of 1.4mm² (1.4Sq), providing balanced transmission with low resistance and ample capacity for detailed, high-resolution audio signals across the frequency spectrum. This configuration supports wide dynamic range, making it well-suited for transmitting complex, information-rich sources.
For insulation, the conductors are wrapped in polypropylene (PP) which is a low-dielectric material that helps maintain signal integrity, while the outer sheath is made of soft PVC (polyvinyl chloride), chosen specifically for flexibility and ease of routing in various installations. The overall outer diameter is a compact φ7.5mm, ensuring the cable remains manageable and discreet without sacrificing build quality.
