Monoprice 113722 16 AWG 2-Conductor CMP Speaker Wire

The Monoprice 113722 is 16 AWG, two-conductor, CMP-rated speaker wire built for permanent in-wall installation where fire code compliance and long-term signal integrity are non-negotiable. The CMP Plenum rating is the cable's defining specification: it qualifies for use in air-handling plenum spaces — the drop ceilings and raised floors that HVAC air circulates through — where standard PVC-jacketed cable is prohibited by building code. For AV integrators and custom installers, specifying a plenum-rated cable from the outset eliminates the risk of a failed inspection and a costly wall re-open. The 100% oxygen-free bare copper conductors keep resistivity low across the cable's service life, which matters in a run that will be sealed in a wall for a decade or more.

At 16 AWG, the 113722 is well-suited to standard 8-ohm residential speaker loads at run lengths up to roughly 80 feet — covering the majority of in-room and multi-room residential installations and light commercial deployments. The red and black conductor identification makes polarity management straightforward across multiple runs, and the softer-than-typical plenum jacket reduces the friction that makes long pulls through conduit or tight wall cavities laborious. The 50-foot spool is sized for single-room and shorter commercial runs; larger projects will require multiple spools or a step up to bulk packaging. Monoprice's lifetime warranty backs the cable against manufacturing defects — a meaningful assurance for a product that's meant to live permanently inside a structure.
