Pair of 13 feet each (4 meters) premium pure copper 14-Gauge speaker cables with 245 fine strands per conductor. Compared to copper-clad-aluminum cable, pure copper cable has 30% lower resistance, better flexibility, and greater durability. Each cable is terminated using gold-plated 4mm banana plugs on both ends. The all-metal banana plugs are purpose-made for high current and low loss applications with a solid core and 9 contoured contact springs. Ultra-slim connector design eliminates needless bulk for a clean and uncluttered installation. The connector holds firmly once fully inserted and has no exposed metal parts, reducing the chance of accidental shorts. Hand-assembled using soldered joints and heat shrink tubing. This construction method results in the best possible audio signal transfer and is also exceptionally durable, ensuring many years of reliable performance. Dual-layer jacket design with a firm inner jacket for cable stability and a supple outer jacket for excellent protection against abrasion while maintaining flexibility. Red polarity stripe together with color-coded connectors helps prevent connection mistakes.
