Choice™ Series 16AWG Oxygen-Free Pure Bare Copper 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 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: Copper, copper, copper

Cons: Quality control for measurement could be better

This wire is about the same price as the low priced stuff you can find on the shelf at your local home center, but it is the same quality product as the much more expensive wire. Very easy to work with, strips cleanly, and a nicely clear, untinted jacket. My only complaint is that my 100 ft spool was short by a goodly amount. Fortunately, this is Monoprice, who calculated a larger refund than I requested and provided it with no questions asked. The product is inexpensive and high quality. The customer service is even higher quality.

Pros: Lays flat, hides well, thick insulation

I purchased this wire for a recent home theater system upgrade. The wite was very easy to work with and lays flat quickly at room temperature. Was easy to hide between the carpet and baseboard around the room.

Fairly priced.

Cons: None

Needed to replace speaker wires with a longer run. This wire did the trick and appears well constructed.
