    Access Series 14AWG CL2 Rated 4-Conductor Speaker Wire, 250ft

    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.

    Can this type of wire be used for an outdoor system? Thinking of running under ground in PVC pipe ..

    BEST ANSWER: I'm doing the same thing, except running it above ground inside a heavy duty drip line hose that was the wrong size for anything else, then use shrink tube when it attaches to the speakers. Been working well for about a year ... so far so good.

    Great Product (spool needs work!)
    I would have given this a 10, but the very low quality wire spool gave us fits as we ran hundreds of feet of cable.

    Anyway, we're building a 3500 sq ft house and used this wire to prewire numerous rooms for in-ceiling, stereo speakers and impedance-matching volume controls. So being able to pull four cables in one run was extremely convenient.

    The cable itself is exactly as promised - durable, high-quality, etc. The 14/4 saved us a great bit of time over 14/2.

    But as soon as we began to pull wire, the cardboard spool came apart and created a large, heavy, jumbled mess. We worked through it, but it would be nice to see a spool that was glued together so the wire would never have a chance to fall off the spool prematurely.

    Here's a tip on how we worked through the issue: before you begin to pull wire, take a spool out of its box, remove the plastic wrapping, and then put it BACK in its box. Then, re-close the box (with the spool inside), placing the box's flaps OVER one another. That will "tighten" the box over the spool.

    Then wrap the box with duct tape so it tightens over the spool as much as possible. Finally, cut a hole in any one corner of the box, and pull your wire thru that. With the snug fit, it will keep the sides of the spool tight, but the "axis" of the spool will spin freely, allowing you to pull the wire without tangle.

    Works perfectly!
    This is a quality speaker wire, easy to use and flexible. 4 conductor in one casing, great for stereo pairs. I used this for a whole house audio install and it made it so easy. Would definitely use again.

    PROS: 4 conductor in one casing, great for stereo pairs

    CONS: None so far

    Great Wire, Great Price
    I could really care less about the spool, but thought it should be mentioned for those who may care about trivial things. The quality is where it counts in this product the wire. Recently had an (unrelated) RMA to process with them, (which can be the downfall of lesser companies), could not be happier with their service! That confirmed it, I will be a Monoprice customer forever!

    PROS: Well manufactured.
    Good quality

    CONS: Poor quality spool
    This is exactly what I needed. And the quality of the wire could not be better. If I had one thing to improve it would be the box. I had problems getting the wire to come off the spool. This was a small issue. It may have even been my error. I am not a pro so I do not know the tricks. :) I Plan to buy more of this to finish the rest of my home audio / theater install.

    Need more than you think
    Running speaker wire in 4500 sq ft new house with 12 zones and 24 total speakers. I ordered 750 sq. feet and ended up needing two more rolls of 250 sq ft each to complete the project. even though you only run one line for a pair of speakers, it still seemed to go faster than I thought. but seems like solid wire and I would buy again.

    It's all good
    Very happy with all aspects of Monoprice. The quality of everything I have purchased here so far is outstanding, and far less than you'd pay at retail stores or online for that matter.

    PROS: fast shipping, great product, reasonable prices

    CONS: none

    Fast and Economical
    overall very satisfied customer, I will be making future purchases and recommending Monoprice to my friends.

    PROS: product was shipped quickly, is a better product and sold well under what the box stores charge you
