Access™ Series 18AWG CL2 Rated 2-Conductor Speaker Wire, 250ft

Get the most out of your home audio system with high quality, oxygen-free, pure bare copper speaker wire from Monoprice!

This speaker wire features two conductors made of high purity (greater than 99.95% 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. CCA is only about 68% as conductive as pure bare copper. This additional resistance is added to the impedance of your speakers and can negatively effect the sound.

For the wire to have no audible effect, the total wire resistance should be no more than 5% of the lowest impedance of your speakers. Even speakers rated for a nominal 8-ohms, may dip to as low as 4-ohms at some frequencies, which further reduces the total cable resistance allowed in the 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.

For example, a 16AWG 2-conductor Pure Bare Copper speaker wire has a total resistance of 1.636 ohms per 100 feet (both directions must be considered). By comparison, a 16AWG 2-conductor CCA speaker wire has a total resistance of 2.406 ohms per 100 feet. Assuming 4 ohms is the lowest impedance of your speakers, a speaker wire run can be no more 0.2-ohms total. 10 feet of Pure Bare Copper would be 0.1606 ohms, well under the 0.2-ohm limit. On the other hand, 10 feet of CCA would be 0.2406 ohms, well OVER the 0.2-ohm limit.

Each conductor is jacketed with color-coded PVC for easy polarity identification. The entire cable assembly is jacketed in a white, CL2-rated PVC material. The 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: commercial grade!

Cons: not really a con but...not available in black for external contrasting.

Been using this 18/2 as well as the 18/4, 16/2 & 16/4 for many years. Hands down commercial quality and will save you a boat load compared to your local home improvement or ANY! online stores.

Pros: Price, durability, quality

Cons: None

Ordered this for a weight room in my school. The product was very easy to use and install. The price was a major plus...this would have cost triple at a box store in my town. And, the sound quality from the wire is excellent.

Pros: Great price, great quality.

This was the perfect amount of wire for wiring my house to my receiver. This is high quality wire that can be trusted to push sound with little distortion.
