    Access™ Series 18AWG 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 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.

    Monoprice has the best prices on quality cable. You know this because you're shopping here. This is good cable for a good price. If this is the kind of cable you need, you should buy it.

    Good wire

    Pros: Good for short runs.
    Strong outer insulation

    Cons: Outer insulation could be a bit tighter.

    I used this wire for some short runs. Just recently realized speaker wire gauge is important for proper home theater setups. Ended up having to order 14 gauge for some longer runs. I wish this was available in a larger spool, maybe 250ft.

    Great wire

    Cons: Outer insulation could be tighter, currently the speaker wire has lots of wiggle room.

    I like the wire, wish the outer insulation was tighter but aside from that it's good.
