The G2 is a directionally-controlled 15 AWG speaker cable is built around a Semi-Solid Concentric design.
Semi-Solid Concentric Conductors
Semi-Solid Concentric conductors significantly reduce strand-interaction, a major source of dynamic distortion in cables.
Long-Grain Copper Metal
High-purity Long-Grain Copper (LGC) conductors minimize distortion caused by grain boundaries.
Directionality
All conductors controlled for RF-noise directionality.
