Wirepath NST-164-500-BLK Speaker Wire 500 Ft Black

Product Description

The WIREPATH NST-164-500-BLK is a non-plenum rated audio speaker wire designed for in-wall and structural audio distribution installations. Supplied in a 500-foot roll and finished in black, this wire is suited for residential and light commercial low-voltage audio runs where plenum-rated cable is not required by code. Licensed low-voltage technicians and A/V installers use this wire to connect amplifiers, receivers, and distributed audio systems to passive speakers throughout a structure. The non-plenum designation indicates it is appropriate for standard wall cavities and conduit runs in non-air-handling spaces.

This speaker wire is used in residential home audio, multi-room audio distribution, and light commercial background music systems. It is well-suited for new construction rough-in work and retrofit installations where accessible wall cavities allow for straightforward cable runs. The 500-foot spool length supports larger projects or multiple speaker drops from a single roll, reducing mid-run splices and simplifying inventory management on the job site.

Key Features

• Non-plenum rated construction suitable for standard wall cavities and non-air-handling spaces
• 500-foot spool length supports extended runs and multi-speaker installations
• Black jacket finish for discreet routing in finished or unfinished spaces
• Low-voltage audio application minimizes code complexity compared to line-voltage wiring
• Sold as a single unit for straightforward procurement

Compatibility

Designed as a standard non-plenum speaker wire for use in residential and light commercial distributed audio systems requiring 16-gauge, 4-conductor speaker cable runs.

Installation Notes

Installation should be performed by a licensed low-voltage technician or qualified A/V installer familiar with local building codes and NEC Article 725 requirements for Class 2 and Class 3 wiring. Confirm with the authority having jurisdiction whether non-plenum cable is permitted in the intended installation space before routing. Avoid running low-voltage speaker wire in the same conduit or cavity as line-voltage conductors without proper separation. Power down connected amplifiers and audio equipment before making terminations.
