Rocket 88 Speaker Cable 12' PairSOLID PERFECT SURFACE COPPER+ (PSC+) CONDUCTORS Solid conductors prevent electrical and magnetic strand interaction. PSC+ Solid Copper minimizes distortion caused by grain boundaries and maximizes linear RF Noise Dissipation. DOUBLE STAR QUAD GEOMETRY The relationship between conductors defines a cable's most basic electrical values (capacitance and inductance). However, even when those variables are kept in reasonably neutral balance, the particular
