Rocket 22 Speaker Cable 2.5m x 2 SureGrip 300 BFA/Banana Silver (set of 4 pair) Rocket 22 Pants Termination AudioQuest Rocket 22 Speaker Cable Key Features Primarily Perfect-Surface Low-Distortion Copper (PSC) 20% Lower Impedance than Rocket 11 Ideal for Full-Range and for Single-BiWire Semi-Solid True-Concentric Conductors Gauge - 2 x 3.31mm Direction Controlled for Optimum Noise-Dissipation LONG-GRAIN COPPER/PERFECT-SURFACE COPPER CONDUCTORS Rocket 22 uses a carefully finessed blend of Long-Grain Copper (LGC) and high-purity Perfect-Surface Copper (PSC). LGC has fewer impurities and fewer internal grain junctions than standard OFHC copper, while the even smoother, purer surface of PSC further eliminates harshness and improves clarity. All AudioQuest conductors are direction-controlled for optimum noise dissipation. SEMI-SOLID CONCENTRIC CONDUCTORS Semi-Solid Concentric conductors are a far-superior performance alternative to typical stranded conductors. Semi-Solid Concentric conductors use fewer, larger strands that do not change position down the length of the cable. The strands maintain their fixed, rigid relationships, reducing distortion, improving resolution and dynamics, and greatly minimizing harshness and confusion due to strand interaction. IDEAL FOR FULL-RANGE OR SINGLE-BIWIRE CONFIGURATIONS Use Rocket 11 as a full-range cable, with red (+) and black (-) conductors grouped together, or, when the speakers provide separate bass and treble inputs, further optimize system performance by biwiring. DOUBLE LOW-INDUCTANCE TWISTED PAIR GEOMETRY A 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, 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 extension
