Monoprice 18AWG 2-Conductor Speaker Wire (CMP Plenum) — 500ft, Black

Monoprice speaker cable built for safe in-wall use and supported by Monoprice’s Lifetime Warranty. The CMP (Plenum) rating confirms the cable meets required fire-safety and insurance standards for installation inside residential and enterprise-class buildings. Audio-grade conductors are made from high-purity, oxygen-free bare copper to ensure clean signal transfer. This 2-conductor, 18AWG cable comes on a 500ft length with a black outer jacket. The plenum-rated jacket is manufactured from a higher-quality, softer material that provides greater flexibility than traditional plenum jackets, making routing and handling easier. Conductors are clearly color-coded red and black for quick polarity identification.
