    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.

    Is this copper clad aluminum wire?
    A shopper on Jan 4, 2018
    BEST ANSWER: the access series purports to be 99.9%. Oxygen free copper. It seems to be copper, but the description is hazy ie is it 99% oxygen free or 99% copper.
    Hey, is this wire Shielded? That is, does it have a metal foil around the wires to protect form electromagnetic noise?

    Nimbus Series 18AWG 4-Conductor CMP-Rated Speaker Wire, 100ft
    Nimbus Series 18AWG 4-Conductor CMP-Rated Speaker Wire, 100ft
    BEST ANSWER: No this cable is not shielded. Most speaker cable is not shielded since there is usually no further amplification to the signal along this cable.
    What is the outside diameter of this 4-conductor 18AWG cable? Thank you.
    A shopper on May 30, 2017
    BEST ANSWER: About 1/4"
    Can I crimp an RJ11 (telephone) connector on the 18 AWG or will the wire strands or jacket be too large to fit?

    Outstanding wire for the price
    Can't say a single negative thing about this wire. Jacketing and insulation are great. I used this not for audio, but to distribute 48 PWM signals for a very large RGB LED array. I was pleasantly surprised that the insulation had very little or no shrinkback when tinning and soldering, which I was concerned about due to the price. Overall an outstanding value - you can't go wrong here.

    Using to make HiFi headphone cables
    im using this to make headphone cables for my hifiman cans. the cables are fractions of a mm too fat to fit in my smc connections but can easily be shaved with a razor. next time ill get the next size down. no complaints for the cables intended purpose. would have given 10/10 if inner shielding/insulation was just a hair slimmer. average joe wont have this issue.

    PROS: clean sound, quality copper, flexible enough for my needs.

    CONS: none per intended purpose.

    Great Product Great Service
    This is the first time I've ordered speaker wire from monoprice.com. I ordered the 18AWG CL2 Rated 4-Conductor Loud Speaker Cable - 100ft for an automotive active install. I ordered Friday and got it Wednesday. That is fast shipping. Great Service. This can't be beat for $22 shipped for 200 feet of speaker wire.

    Can't Beat It
    Great cable at an unbeatable price. Monoprice is the only place I buy cables anymore because they make the exact same product for a fraction of the price. Copper is copper, people. You can't go wrong with Monoprice cables.

    PROS: Great cable.

    Clean with the right color coding for easy whole home audio installation.
