Monoprice 12AWG 4-Conductor Speaker Wire, CL2 Rated, Oxygen-Free Bare Copper, 250ft, Black

This 250ft Monoprice speaker cable is 12AWG with four individual conductors, each insulated in color-coded PVC for straightforward polarity identification. The conductors are oxygen-free, pure bare copper — greater than 99.95 percent pure — providing better conductivity than the copper-clad aluminum (CCA) commonly found in cheaper speaker wire. Using pure bare copper helps keep the amplifier’s load closely matched to your speakers’ impedance curve for more accurate performance. The cable carries a CL2 rating, meeting fire-safety and insurance requirements for in-wall installation in residential-class buildings.
