Choice™ Series 12AWG Oxygen-Free Pure Bare Copper Speaker Wire, 50ft

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 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.

One side of the clear outer PVC jacket is marked with an easily visible blue stripe to indicate polarity.

Oxygen Free Speaker Wire

Pros: For the money, this is exceptional speaker wire. I have been using Kimber Cable 8-wire cable since 1996 and decided to experiment a bit, making my own. I'm still evaluating, but must say that I am impressed with what I've heard thus far. While this cable may not be quite as smooth as the Kimber, it would be great for most people that are using cheap, thin stuff. It is worth every penny.

Cons: None that I can think of, especially considering the price.

Great cable for the money - may be able to beat it with a cable that has more strands, but cannot swear to that.

I have several kinds of cable. This works very well ... if used correctly. I do not use it with each of its two wires going to each speaker terminal. I connect the two conductors in parallel - twisted together at each end - and connect them to one speaker terminal. Then I take a second length and do the same thing for the other speaker terminal. This gives me two physically separate wires - of two conductors each. The physical separation seems to sound clearer. And the two conductors in parallel equate to 10 gauge for each separate run.
