Bulk speaker wire can be used for creating custom-length speaker patch cables or for cable runs in a home or business. Our professional-grade speaker wire is comprised of oxygen-free copper conductors, ensuring that it delivers audio signals with the highest fidelity. The 12 AWG speaker cable is best suited for long runs. The thickness of the conductors ensures minimal signal loss over the distance but makes the cable less flexible and more troublesome to terminate than thinner gauge wire.
