    Access™ Series 12AWG 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.

    Pros: Very heavy wire that helped running thru conduit.

    Cons: None for me

    Purchased the 100' 12 AWG to run a wire up inside a wall, across an attic and down inside another wall for a pair of rear speakers. The wire worked perfectly for this job. Very satisfied with the purchase. I left the wire in the garage for a couple of hours on a 90 degree day and then straightened the wire very easily.

    quality cable

    Pros: Cable is well made, easy to work with - even at lower temps, 4 conductor each with separate color jacket makes hookup easy, priced right especially when compared to similar quality cable from other manufacturer.

    Cons: my rating of 9 is only because a 10 rating would have a super flexible mogami type outer shell. But there's no real con.

    Simple decision... if you need 12 guage 4 conductor cable for speaker runs... this is your choice. I searched around for similar products and Monoprice had the right price. Shipping was a bit of a factor but such is life.

    No brainer, order the cable, you won't be dissapointed.

    Pros: Quality cable at a decent price

    Cons: none at this price

    Cable is as good or better than anything I've seen near this price. Straightens and holds its shape well after unrolling.

    exactly what i was looking for

    Pros: i was looking for cable i could put in the wall to hide with little effort and this was perfect.
    fantastic quality, well insulated and the 4 wires per strand helps with fast installation.

    Cons: cable is thick and can be hard to work with, but really isn't a con as thats what you get with the gage of wire and having 4 wires together.

    i would recommend this product to anyone looking to simplify wire installation with a quality product. do not hesitate to purchase.
