Plenum-Rated 16 AWG Speaker Wire

Monoprice 113725 is a CMP-rated 16 AWG speaker wire designed for safe installation inside walls and plenum air spaces of residential and commercial buildings. It uses 100 percent pure oxygen-free bare copper conductors to ensure accurate signal transmission. The 499.87 ft spool provides ample length for whole-home or multi-room audio projects.

Fire-Safe Jacket for Continuous In-Wall Runs

The CMP-rated jacket resists flame spread and meets strict fire safety and insurance requirements for plenum ducts and airspaces. This rating allows the cable to be run continuously through building ventilation areas without conduit. The jacket material is formulated to be softer and more flexible than traditional plenum jackets, easing long pulls through studs and joists.

Two-Conductor Design for Single-Speaker Connections

This version carries two conductors intended for connecting a single speaker per run. Installers needing to wire speaker pairs from a single cable pull should select the four-conductor variant instead. The color-coded inner jackets simplify polarity identification during termination. Buyers requiring a different gauge or a non-plenum rating for exposed runs should look elsewhere.

Questions about this item

Does this 16AWG plenum-rated cable generate heat or draw power during continuous daily use?

No. The cable is a passive conductor with 100 % pure oxygen-free bare copper and no active electronics, so it produces no heat and consumes no power.

What connectors or terminals do I need to terminate this 2-conductor 16AWG speaker wire?

You will need speaker terminals, banana plugs, spade lugs or bare-wire binding posts that accept 16AWG cable; the wire itself ships without any connectors attached.

Can I run this CMP-rated 16AWG wire alongside existing in-wall speaker cables of different gauge?

Yes. The plenum-rated jacket is fire-retardant and approved for shared air-space installations, so it can be pulled through the same ducts or walls as other speaker cables regardless of their gauge.
