Choice™ Series 12AWG Oxygen-Free Pure Bare Copper Speaker Wire, 300ft

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.

Pros: Great quality speaker 12 AWG and at a good price. Oxygen free a must for speakers.

Cons: I know speaker wire is made of copper and thus can be heavy but I found the shipping charge a bit too high IMHO.

This is an awesome 12 AWG speaker wire.

Excellent Quality for the Money

Pros: Good quality, large gauge, fairly flexible, inexpensive

Cons: None

If you take the time to wait for these wires to arrive, they will be worth it. I tried buying from local retailers, but they don't seem to carry 12G speaker wires. And if they do you will pay about 3x the price you will pay at Monoprice. These speaker wires are excellent. I consider myself an audiophile, and these cables do a great job of connecting my surround sound speakers to my AV processor.
