Mediabridge Ultra Series subwoofer cable connects a subwoofer speaker to an audio component like a stereo receiver or sound system, while offering excellent bass response & flexibility. This Low-loss, wide spectrum coaxial cable is the ideal medium for low-frequency signals produced by subwoofers, providing Deep/precise audio quality. Built with a copper clad center conductor, dielectric insulation, aluminum braiding & 2 layers of foil shielding, for natural sounds & rejection of hum/static that occurs when devices are placed near each other. A split-tip center pin ensures high contact pressure & conductivity. Uniquely gripped Color-coded molds & corrosion-resistant gold-plated RCA connectors provide a consistently tighter fit than commonly rolled cables with wider tolerances. Ultra Series cables are made from premium materials for a pro-grade output. This cable is finished in a durable, yet pliable PVC jacket for easy installs.
