Io Audio Technologies CL3P 12/2 Plenum-Rated Speaker Wire

Io Audio Technologies CL3P 12/2 Plenum-Rated Speaker Wire is a 12AWG, 2-conductor stranded copper speaker cable designed for commercial AV, distributed audio, and multi-room sound systems. This wire features a UL13 CL3P plenum rating with low-smoke and flame-retardant insulation, making it suitable for installation in air-handling spaces. The CL3P cable is supplied on a 500ft spool and includes a durable white PVC jacket that remains flexible for easier routing and termination. The cable includes red and black insulated conductors for easy polarity identification and an integrated rip cord for faster and cleaner jacket removal during termination. Footage markings are printed every 2 feet to help installers track cable usage and remaining length. The CL3P speaker wire is engineered for reliable signal transmission and combines code compliance, installation efficiency, and long-term durability.
