Bring your sound system to life with the Supra Classic 2×4.0 Blue — a powerful and flexible speaker cable designed for serious Hi-Fi and home-cinema enthusiasts.
Each conductor is made from oxygen-free copper (5N purity) with a protective tin coating, ensuring smooth current flow, long-term stability, and minimal signal loss — even under heavy load.
