Pre-assembled Y-subwoofer cable for connecting active subwoofers to a home-cinema system! Ideal for connecting an active subwoofer (stereo input) to an AV receiver (mono output). Due to the large cross-section of the inner conductor and the coaxial design, this Oehlbach cable is particularly suitable for transmitting low frequencies. In addition, the inner conductor made of oxygen-free OFC copper s an absolutely precise and powerful bass response. Effective copper braid shielding eliminates all signal interferes and ensures perfect transmission quality.
