4 Core Round Speaker Cable - OFC 4-Conductor Cable for Bi-Wire, Stereo & Dual Circuits
4 core round speaker cable is a four-conductor oxygen-free copper (OFC) audio cable built in a single round jacket, designed to carry two independent audio channels in one run. It is the installer-preferred choice for bi-wiring and bi-amping high-end speakers, running a stereo pair (left + right) through one cable, or carrying two separate 100V/70V distributed audio circuits in a single pull. Jiaxing Doublewin Cable Co., Ltd manufactures this cable in-house in Haiyan, Zhejiang, China, available in 4×12 AWG, 4×14 AWG, 4×16 AWG and 4×18 AWG, and supplies it in bulk to audio distributors, integrators and OEM/ODM partners worldwide.
Why Choose Our 4 Core round Speaker Cable
Where a 2-core speaker cable carries one speaker circuit, a 4-conductor speaker cable carries two - which halves the number of cable pulls on many jobs and enables bi-wiring, stereo-in-one and dual-circuit installations that would otherwise require two separate 2-core cables.
