In-wall rated speaker cable

Monoprice 113709 is a CMP plenum rated speaker wire built for installation inside walls and air spaces of residential or commercial buildings. The two conductor design uses 12AWG oxygen free bare copper for accurate signal transfer. A 250 foot pull box suits whole home or multi zone audio projects. The black jacket is softer and more flexible than traditional plenum cables for easier routing.

Thermals noise and power

As a passive copper cable the product generates no heat and adds no audible noise to the signal path. Power handling is determined by the connected amplifier and speaker impedance rather than the wire itself. The plenum jacket resists flame spread and meets fire safety codes for duct and airspace use. No active cooling or power supply is required.

Replaces standard non rated wire

This cable replaces ordinary speaker wire when building codes or insurance require a plenum rating for in wall or ceiling runs. It is not suited for buyers who need a four conductor version for bi wiring or for connecting speaker pairs from a single pull. The jump is worth it whenever fire rated cable is mandated or when oxygen free copper clarity is preferred over basic stranded wire.

Questions about this item

How do I pull the 12 AWG CMP-rated cable through walls and what step is often missed?

Feed the 76.2 m spool through stud cavities or conduit, then verify the CMP jacket passes local plenum inspection before closing the wall; the missed step is skipping that sign-off.

What upkeep or replacement will the 12 AWG oxygen-free copper conductors need over time?

The bare copper cores require no scheduled maintenance; only physical damage or corrosion at terminations would ever demand a replacement run.

At what point does the CMP jacket become the limiting factor during a long, high-power run?

The plenum-rated jacket is the first limit — sustained heat above its rated temperature degrades the fire-retardant compound before the 12 AWG conductors reach ampacity limits.
