XXL® Sub Xtreme

High-end subwoofer RCA phono cable

A top class, high-end subwoofer cable! The 5-star cable is specifically designed for transmitting low frequencies thanks to the particularly large cross-section of the inner conductor and the coaxial configuration. The inner conductor, which is manufactured from high-purity long crystalline HPOCC copper, ensures a precise and powerful bass response. The silver-plated copper braid dual shielding also reliably eliminates all signal interference. Equipped with the innovative XXL Silicon Evolution RCA plugs this cable always ensures optimum bass performance.
