18/4 Plenum Audio Cable - White - 500 ft

We offer the plenum rated White 18/4 audio cable required for commercial audio system installations. Plenum rated audio cable is required in audio installations where wire is ran in a plenum open-air ceiling environment. It is important to understand your local building codes and install the right audio cable to support them. The plenum rated 18/4 wire features a special compound in the jacket that combats burning and hinders the release of deadly toxins in the air if the wire is caught on fire.

Our 18/4 plenum audio cable features a White jacket, red, black, white, and green conductors, and an internal rip cord. All of our speaker wire is manufactured using 99.999% oxygen-free copper. This 18/4 plenum speaker wire is 300 volt rated and includes 4 color coded conductors.

Using 4 conductor speaker wire is very common in applications where audio cable is ran from a volume control to an audio receiver or amplifier. Having 4 colored coded conductors makes organizing and identifying speakers much easier.
