Plenum-rated speaker wire

This CMP-rated 12AWG cable meets fire-safety requirements for installation in plenum ducts and airspaces of commercial buildings. The external jacket is specially treated to resist flame spread, making it suitable for both residential and professional audio runs.

Oxygen-free copper conductors

One hundred percent pure bare copper conductors are colour-coded inside the main CMP-rated jacket for easy identification. The two-conductor design carries a single speaker channel, while the oxygen-free copper aims to preserve signal integrity over the full 304.8 metre length.

Lifetime warranty included

Monoprice backs the wire with a lifetime warranty, giving installers long-term assurance for permanent in-wall or ceiling deployments. No additional connectors or termination tools are bundled, so the installer supplies their preferred ends.

Questions about this item

What does the CMP rating on this 12AWG speaker wire allow?

The CMP rating means the fire-retardant jacket is approved for installation inside plenum ducts and airspaces in commercial buildings.

What conduit or raceway size is needed for this 1000ft spool of 12AWG cable?

The 12AWG two-conductor construction with an overall CMP jacket typically fits in 3/4-inch or larger conduit; verify fill ratios for your specific run.

How do you correctly prepare the oxygen-free copper conductors for termination?

Strip only the outer CMP jacket, then the colour-coded inner jackets, twist each bare copper strand tightly, and terminate — do not nick the conductors.
