Monoprice 12 AWG Oxygen-Free Copper Speaker Wire – 300 Ft, CL2 Rated, Blue Stripe

Overview

Upgrade your home audio wiring with Monoprice speaker wire crafted from high-purity oxygen-free copper. The two-conductor design uses copper with purity greater than 99.95%, delivering a clean, low-resistance path from your amplifier to your speakers. The clear PVC jacket keeps the conductor visible and protected, while a bright blue stripe on one side clearly marks polarity for easier setup, even in dim rooms.

Key benefits

• 99.95%+ pure oxygen-free copper conductors help minimize resistance and preserve detail across longer runs.
• 12 AWG two-conductor design on a long spool provides ample length (300 feet) for versatile installations without frequent re-spooling.
• Clear flexible jacket with a visible blue polarity stripe supports quick, confident wiring and reduces installation guesswork.
• Polarity marking on the jacket helps ensure correct connections, contributing to a cleaner, more organized setup.

In practical setups

• Well suited for connecting speakers in home theaters, living rooms, or stereo systems where a stable signal path matters.
• CL2 rating indicates suitability for in-wall use when installed in accordance with local electrical codes, enabling tidy, hidden runs where permitted.

What you get is a straightforward, reliable speaker wire that supports real-world needs: a clear signal path from amp to speaker paired with a simple polarity cue and a robust copper core. As with any wiring, optimal results depend on the rest of your system and room acoustics, but many users appreciate the easy handling, long length, and visible polarity indicator when laying out speaker runs.
