AudioQuest X2 Unterminated Speaker CableThe X-2 is a 14 awg speaker cable which uses semi-solid concentric-packed long-grain copper.In a conventional multi-strand cable distortion caused by electrical and magnetic strand interaction are compounded as each strand changes position within the bundle. In an Audioquest Semi-Solid Concentric-Packed cable strands within the bundle maintain their fixed rigid relationships significantly reducing distortion.This copper is considered "Oxygen-Free Copper." What this means is that the copper is actually oxygen-reduced but is not selected for low distortion. AudioQuest's Long-Grain Copper means fewer impurities less grain junctions and lower distortion. Additional Information:Cable Name: X-2 Unterminated Speaker CableTermination: Unterminated
