Access™ Series 18AWG CL2 Rated 2-Conductor Speaker Wire, 50ft

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.

Didn't work

by Monoprice Administrator

Truly sorry to hear PID 4044 isn't working for you. So that I may better understand the issue, can you describe your setup including all devices and cables in use as well as elaborate on how it is not working? Have you tried testing with a different device to see if anything changes? Please let me know so that I may better assist you. Thanks in advance!

Pros: price and durability, it's white!

Cons: smaller than i thought.

I intended to use this for my fronts and center.each being 8 ft works fine for that.I took rubbing alcohol to get the print off it.haven't yet but will install along white baseboard and be invisible.yes using it outside of wall.I think you also may want bigger if u use outside of wall cause bigger can be bent around more.being moved with you n all.I will get the same but 14g for surrounds next.
