A cable whose job is to transmit just two or three octaves of audio information enjoys the most relaxed requirements of any interconnects in the system. Or does it? Long lengths, punishing environmental factors and the necessity to handle extreme dynamic range are all part of the subwoofer interconnect's job description. Velocity Bass Management Subwoofer Cables from Cables To Go offer superb impact and detail while maintaining a "tough as nails" built quality! Twisted pair oxygen-free copper wire and foamed PE dielectric are optimized for bass signal transmission. The low-loss 100% foil and spiral-wound oxygen-free copper shielding protect the important bass signals from electromagnetic interference (EMI) and radio frequency interference (RFI); thus increasing impact and detail. A tough, flexible jacket and 24K gold-plated heavy-duty contacts ensure a lifetime of performance.
