Cables Direct Online 500FT 14AWG (14/2) CL3/CMR In-Wall Speaker Wire – 99.99% OFC Bulk Audio Cable for Home Theater & Surround Sound

This 500FT spool of 14AWG (14/2) speaker cable from Cables Direct Online is built for high-performance audio and permanent in-wall installations. The conductors are 99.99% oxygen-free copper (OFC) to maximize conductivity and minimize signal loss for clear, high-fidelity sound. Fire-rated CL3/CMR construction makes the cable suitable for residential and commercial in-wall use, meeting flame-resistance and code compliance requirements. Compared with copper-clad aluminum (CCA), this OFC cable offers lower resistance and more efficient power transfer. A flexible, durable PVC outer jacket simplifies routing through walls and tight spaces while protecting against abrasion, kinking, and corrosion. Ideal for home theater and surround sound setups, smart-home wiring, car audio projects, low-voltage LED runs, and other custom low-voltage installations.
