Get the most out of your home audio system with high quality, oxygen-free, pure bare copper speaker wire from Monoprice. This speaker wire features four conductors made of high purity, oxygen-free bare copper. Pure bare copper is a superior conductor used in speaker wire. Using pure bare copper speaker wire ensures that the total load put on the amplifier remains as close as possible to the impedance curve of your speakers. Each conductor is jacketed with coded PVC for easy polarity identification. The entire cable assembly is jacketed in a CL2-rated PVC material.
