Speaker Cable w/ SureGrip 300 Connectors Keep audio signals clean and unaltered with AudioQuest Rocket 22. The carefully finessed blend of Perfect-Surface Copper (PSC) and Long-Grain Copper (LGC) is packed in a semi-solid concentric pattern with reversing spiral forms to keep wire position and contact optimal for minimum signal distortion. Semi-Solid Concentric Perfect-Surface Copper (PSC) and Long-Grain Copper (LGC) ConductorsIn a conventional multi-strand cable, distortion caused by electrical and magnetic strand interaction is compounded as each strand changes position within the bundle. In an AQ Semi-Solid Concentric cable, strands within the bundle maintain their fixed relationships, significantly reducing distortion. A carefully finessed blend of Perfect-Surface Copper (PSC) and Long-Grain Copper (LGC) allows a smoother and clearer sound than cables using regular OFHC (Oxygen-Free High-Conductivity) copper. Double Spiral-Pair GeometryA typical speaker cable with parallel conductors has fairly high inductance, smearing energy across time, which results in sound that is dull and unfocused. In Rocket 11/22, the two conductors in each half of the cable are twisted around one another, providing lower inductance, greater clarity, and superior bass-to-treble frequency extensionPVC Insulation Technical Specifications Cable Configuration Pair Metal Semi-Solid True-Concentric Perfect-Surface Copper (PSC) & Long-Grain Copper (LGC) Noise Dissipation Carbon-Based Noise-Dissipation Geometry Double Spiral-Pair Gauge 12 AWG Signal Type Analog Cable Length 8 ft = 2.4 m Jacket Black PVC with Blue Stripes CL3/FT4
