Overview

High-Quality Audio Connection with Monoprice Speaker Wire

Experience superior audio quality with Monoprice Speaker Wire. This 18AWG speaker wire features two conductors made of high-purity, oxygen-free bare copper, ensuring optimal signal transfer. The color-coded PVC jackets make polarity identification easy, while the CL2 rating allows for safe in-wall installation.

Key Specifications:

  • Brand: Monoprice
  • Model: 141393
  • Type: Speaker Wire
  • Conductors: 2-Conductor
  • Gauge: 18AWG
  • Conductor Material: Oxygen-Free Bare Copper
  • Length: 250 Feet
  • Jacket: CL2 Rated PVC

Key Features

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.

Using Pure Bare Copper speaker wire ensures that the total load put on the amplifier remains as close as possible to the impedance curve of your speakers.

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

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

  • Features two conductors made from high purity, oxygen-free bare copper, ensuring superior audio signal transmission.
  • Utilizes pure bare copper, which is a significantly better conductor compared to the copper clad aluminum used in many other speaker wires.
  • Helps ensure the total load on an amplifier remains close to the speakers' impedance curve, optimizing audio performance.
  • Each conductor is jacketed with color-coded PVC, providing easy and clear identification for correct polarity.
  • Carries a CL2 rating, indicating compliance with fire safety and insurance requirements for safe in-wall installation in residential buildings.

👎 Cons

  • The 18AWG gauge might be considered too thin for very long runs or extremely high-power audio systems by some audiophiles.
  • While CL2 rated, users installing in commercial spaces may require higher fire ratings, such as CL3, not offered by this cable.
  • The cable is supplied as a 250ft roll, which may be more length than necessary for smaller installations, potentially leading to excess material.
  • The focus on bare copper, while a pro, means it doesn't offer additional shielding found in some premium speaker cables.
