Plenum-rated 4-conductor speaker wire

Monoprice 116175 is a CMP-rated speaker cable built for installation in plenum ducts and airspaces of commercial buildings. The 16 AWG construction uses four oxygen-free copper conductors to connect speaker pairs in both residential and professional environments. It arrives in a 1000 ft pull box for long continuous runs.

Fire-retardant jacket for air-handling spaces

The external jacket has been specially treated to resist flame spread and carries a UL CMP rating for plenum airspace safety. This rating allows the cable to be routed through building ventilation ducts without additional conduit in many jurisdictions. The black jacket material meets stringent commercial fire codes for in-wall and in-ceiling deployment.

Colour-coded inner jackets simplify pair

Each of the four bare copper conductors is sheathed in its own colour-coded jacket inside the main plenum-rated sleeve. This layout lets installers quickly match polarity when terminating speaker pairs without tracing individual wires. The pure oxygen-free copper aims to preserve signal integrity over the full 999.74 ft length.

Questions about this item

How do I pull the 999.74 ft 16AWG CMP jacket through a plenum duct without kinking the four conductors?

Unreel from the box centre, feed the black CMP jacket straight into the duct, and keep bends wider than ten times the cable diameter so the four colour-coded oxygen-free copper conductors stay aligned.

What part of the Monoprice 116175 will need attention after years in an air-handling space?

Inspect the black CMP jacket annually for abrasion or discoloration; the oxygen-free copper conductors themselves require no maintenance unless the jacket is breached.

At what distance does the 16AWG gauge start limiting power delivery on a 1000 ft run?

On a 1000 ft four-conductor run, 16AWG oxygen-free copper reaches its practical limit around 100 ft for typical 8-ohm speakers before voltage drop affects output.
