Overview

The Monoprice 102791 Choice Series speaker wire delivers 100 continuous feet of 14AWG, 2-conductor cable built with 99.95% oxygen-free bare copper. At 14 gauge, the wire provides approximately 2.5 ohms of resistance per 1000 feet — low enough to ensure negligible signal loss on typical home theater and distributed audio runs under 50 feet. The oxygen-free copper specification means the conductors resist long-term corrosion better than standard CCA (copper-clad aluminum) alternatives, which is a meaningful advantage at termination points where exposed copper meets binding posts or banana plugs over years of use.

This wire is aimed at home theater installers, DIY audio enthusiasts, and anyone running multi-room speaker setups where reliable, low-resistance connections matter. The clear PVC jacket with an integrated blue polarity stripe makes phase-correct wiring straightforward during installation — a small detail that prevents frustrating troubleshooting later. The 14AWG size hits the practical sweet spot for most consumer amplifiers and passive speakers: thick enough to handle high-current demands without voltage drop, yet flexible enough to route through tight spaces. It is not rated for in-wall use, so plan for surface routing, cable channels, or conduit if building codes apply to your installation.

Pros & Cons

👍 Pros

  • 99.95% oxygen-free copper delivers measured resistance of approximately 2.5 ohms per 1000 feet, minimizing signal loss on long runs
  • 14AWG conductor diameter handles up to 15 amps, providing ample headroom for high-power amplifier outputs
  • 100-foot continuous spool on a reel eliminates splices that would increase resistance at junction points
  • Clear PVC jacket with integrated blue polarity stripe allows quick visual verification of correct wiring phase
  • Flexible jacket bends easily around corners and through conduit without kinking or memory issues

👎 Cons

  • Not CL2 or CL3 rated, so it cannot be legally installed inside walls or plenum spaces
  • No sequential footage markings on the jacket, making it difficult to measure exact run lengths without a tape measure
  • Bare copper terminations require banana plugs or manual stripping — no factory-terminated ends included
  • PVC jacket provides no UV protection, limiting suitability for permanent outdoor installations
  • Spool packaging lacks a built-in cutter or dispensing mechanism for controlled unspooling

Frequently Asked Questions

14AWG supports runs up to approximately 80 feet for 8-ohm speakers and 40 feet for 4-ohm speakers before resistive losses become audible. This 100-foot spool gives you flexibility for most home theater and whole-house audio installations.
At 99.95% purity, oxygen-free copper reduces oxidation over time, which helps maintain consistent resistance across the conductor. The practical benefit is long-term reliability rather than an immediate sonic difference — standard copper develops higher resistance as it corrodes at termination points.
No. The PVC jacket on this wire is not CL2 or CL3 rated for in-wall use. For runs through walls or ceilings, you need a fire-rated jacket. This wire is designed for exposed or surface-routed installations.
Yes. 14AWG is more than sufficient for powered subwoofer connections, which typically run short distances. The low resistance of the copper conductors ensures full power delivery to the sub without signal degradation.
One side of the clear PVC jacket has a visible blue stripe running its full length. Use the striped conductor consistently for one polarity (positive or negative) across all your speaker connections to maintain correct phase.
