Overview
Deliver High-Quality Sound to Your Home Audio System
Get the most out of your audio system with Monoprice Speaker Wire. High quality, oxygen-free, pure bare copper ensures the highest audio fidelity, and the CL2 rating makes it safe for in-wall installation in residential buildings.
Specifications:
- Conductors: 4-Conductor
- Wire Gauge: 18AWG
- Length: 100ft
- Conductor Material: Oxygen-Free Pure Bare Copper
- Jacket Material: CL2 Rated PVC
- Color: Black
Key Features
Features 4 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 four conductors made of high purity (greater than 99.95 percent pure), oxygen-free bare copper for superior conductivity.
- Uses pure bare copper, which is a superior conductor compared to copper clad aluminum (CCA) often found in other inexpensive speaker wires.
- Ensures the total load on the amplifier remains as close as possible to the impedance curve of the speakers for optimal audio performance.
- Each conductor is jacketed with color-coded PVC, simplifying polarity identification during installation.
- Possesses a CL2 fire safety rating, making it safe for in-wall use in residential class buildings according to fire safety and insurance requirements.
👎 Cons
- Only specified as 18AWG, which may be too thin for very long runs or high-power speaker systems without some signal loss.
- The wire is 4-conductor, which may be more than needed for a standard two-channel speaker connection, potentially leading to unused wires.
- While pure bare copper is superior to CCA, the specific gauge might still be a limiting factor for audiophiles with very high-end setups.
- The color-coded PVC jacketing, while practical, is a functional feature and not an aesthetic one for exposed installations.
- The CL2 rating focuses on safety for in-wall use and does not inherently speak to the cable's external durability or flexibility.
