Rocket 22 Speaker Cable 8' PairLONG 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
