Overview

The Monoprice 141382 CL2 14AWG 2-Conductor Speaker Wire is built for homeowners and installers who need reliable, high-quality cabling for permanent audio installations. At its core are two conductors made from oxygen-free bare copper with greater than 99.95% purity, a meaningful step up from the copper clad aluminum found in many budget speaker wires. Pure bare copper offers lower resistance and better signal integrity, which translates to cleaner, more accurate audio reproduction — particularly noticeable on longer cable runs where inferior conductors would introduce measurable signal loss.

The CL2-rated black PVC outer jacket is the feature that sets this wire apart for installation purposes. That rating certifies the cable for use inside residential walls, meeting fire safety and insurance code requirements without the need for conduit. The 500-foot spool provides ample length for whole-home audio projects, multi-zone setups, or commercial installations where custom-length runs are pulled to each speaker location. Color-coded conductor jackets simplify polarity matching across all connections, reducing wiring errors that can cause phase issues in multi-speaker systems.

Key Features

Two conductors made of high purity (greater than 99.95 percent pure), oxygen-free bare copper.

Pure Bare Copper is a superior conductor to the copper clad aluminum (CCA) conductors used in most other inexpensive speaker wire.

Each conductor is jacketed with color-coded PVC for easy polarity identification.

Entire cable assembly is jacketed in a black, CL2-rated PVC material.

CL2 rating indicates that the cable complies with fire safety and insurance requirements, making it safe for use inside the walls of residential class buildings.

Pros & Cons

👍 Pros

  • Oxygen-free bare copper conductors deliver cleaner signal transfer than cheaper copper clad aluminum alternatives
  • CL2-rated jacket allows safe and code-compliant installation inside residential walls
  • 500-foot spool provides enough wire for multi-room whole-home audio installations
  • Color-coded conductors make polarity identification quick and error-free during wiring
  • 14AWG thickness supports longer speaker runs without significant signal degradation

👎 Cons

  • 500-foot spool is far more wire than needed for a single-room setup, with no smaller length option listed
  • 14AWG wire is stiffer and harder to route through tight spaces compared to thinner gauges
  • Does not include any connectors or terminations, requiring separate banana plugs or bare-wire prep
  • Black outer jacket may be difficult to label or distinguish from other cable types in crowded conduit runs

Frequently Asked Questions

Oxygen-free bare copper (greater than 99.95% purity) provides superior conductivity and signal transfer compared to copper clad aluminum (CCA). CCA uses an aluminum core with a thin copper coating, which has higher resistance and can degrade audio quality over longer runs.
Yes. The CL2 rating means this cable meets fire safety standards for installation inside walls of residential buildings, making it compliant with building codes and insurance requirements for in-wall use.
14AWG is suitable for most home theater and whole-house audio installations. It can handle longer runs (up to about 80 feet) to 8-ohm speakers without significant signal loss, making it a good choice for multi-room setups.
Each of the two conductors is jacketed in color-coded PVC insulation, allowing easy polarity identification during installation so you can maintain consistent connections across all speakers.
Yes, the 500ft length comes as one continuous run on a spool, which is ideal for whole-home installations where you need to pull multiple custom-length runs from a single source.
