Deliver Premium Audio Quality with High-Purity Copper Wire

Maximize your home audio system's potential with Monoprice Speaker Wire. Featuring high-purity, oxygen-free, bare copper conductors, this wire ensures superior signal transmission and minimal signal loss.

Specifications:

  • Gauge: 18AWG
  • Conductors: 2
  • Material: Oxygen-free, pure bare copper
  • Jacket: Black, CL2-rated PVC
  • Length: 1000ft

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

  • Constructed with high-purity, oxygen-free bare copper conductors, offering superior conductivity compared to copper clad aluminum.
  • The CL2 rating ensures compliance with fire safety and insurance regulations, making it suitable for in-wall installation in residential buildings.
  • Color-coded PVC jacketing on each conductor simplifies polarity identification, streamlining the speaker setup process.
  • The extensive 1000ft length provides ample material for large-scale audio installations or multiple speaker connections.
  • The entire cable assembly is encased in a durable black PVC jacket, providing protection and a discreet appearance.

👎 Cons

  • The 18AWG gauge might be considered relatively thin for very long runs or high-power audio systems, potentially leading to signal loss.
  • While CL2-rated for residential in-wall use, it may not meet more stringent commercial fire safety codes.
  • The cable comes in a single 1000ft length, which could be excessive and cumbersome for smaller, more localized audio setups.
  • The black jacket, while discreet, may not blend as seamlessly in all interior design aesthetics as white or clear options.
  • This cable is designed specifically for speaker connections, making it unsuitable for other wiring applications like data or power.
