Access™ Series 16AWG CL2 Rated 4-Conductor Speaker Wire, 100ft

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 four 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 0.803 ohms per 100 feet (both directions must be considered). By comparison, a 16AWG 2-conductor CCA speaker wire has a total resistance of 1.181 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. 20 feet of 16AWG Pure Bare Copper would be 0.1606 ohms, well under the 0.2-ohm limit. On the other hand, 20 feet of 16AWG CCA would be 0.2362 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.

Good Quality Speaker Wire

Pros: Good quality wire at a much lower price than elsewhere. Was comparable to a roll I saw at a retail store for three times the price with a thinner outer jacket and only 2 conductors.

Was perfect for running through the crawlspace for a couple sets of surround speakers. A little thicker than it looks online but not an issue for me. I'm totally satisfied.

Works great

Ordered 100ft of 4-conductor 16 AWG for my speakers (each speaker has separate inputs for high and low frequencies, so I need 4 cores in the cable not the usual 2). Surprisingly these weren't expensive speakers, they just happen to need 4 core wire. The Monoprice cable is a bit thicker than I need, but sounds great. It arrived in perfect condition. And is a noticeable improvement in sound quality over the standard cable that came with the system.
