    Access™ Series 18AWG CL2 Rated 2-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 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.

    Easy to Work With

    Pros: Right size gauge for my project.

    Cons: none

    Since it's two wires encased with a plastic sheath, it is very easy to thread through the walls. Great value and I have plenty to spare.

    I have been using this cable for over four years every time I install a sound system.

    Pros: Oxygen free copper cable and CL2 rated
    Comes on spools

    Cons: None

    Cannot beat this price for oxygen free copper wire. I needed an extra spool and got it in time to finish the job. Came on spool even though only 100'. Very easy to spool off.

    This is great stuff. It was a definite improvement over the cat 3 I was using. The sound from my system is definitely better.

    Pros: Quality Cable
    Easy to work with
    Solid connection.
    Connect with pin or plug bindings

    Cons: Gage can be thick for basic spring binding receivers

    Good quality speaker wire that can be installed in-wall and meets safety code in Canada.

    This is my 2nd spooled purchased.

    Good price even with expensive delivery charge.
