Built for large commercial and residential installations, our Professional Grade 500-ft speaker cable is designed for pros who want to provide customers with the best quality audio and get the job done quickly and efficiently. Rated for both in-wall and direct burial use, this two-conductor high strand count copper cable provides excellent signal transfer for installations where background music is needed, and the 12-gauge thickness is ideal for long wire runs (over 50 ft) and low-impedance speakers. The reinforced but flexible polypropylene jacket is UV resistant and protects the copper conductors from high heat and cold conditions as well as dirt, dust, and other elements that can degrade cable integrity. Features that cater to demanding integrators include a reinforced box with an easy pull, snag-free design, and tissue-wrapped conductors for quick stripping.This sturdy audio speaker cable also includes two-foot increment printed markers so you can determine how much cable has been used and how much is left on the spool, making long cable runs easier than ever.
