Choice Series™ 18AWG 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.

Looks and feels like quality. Great price

Pros: Can't beat the price for this speaker wire!

Cons: Shipping isn't included. )

This is some great speaker wire. Nice gauge with just the right amount of insulation to go through holes that some other wires of the same gauge simply will not fit in.

Pros: Sound quality is good, easy to feed through holes in floor, and easy to splice with wire tool.

Cons: None

Good quality, and easy for installation. Easy to split the ends, you don't even need a knife to split the wires for connecting.

I've been ordering audio / electronic through monoprice for years. This order was no exception to the quality of transactions I've come to expect. Fast delivery, prices even Amazon can't touch and quality materials. Thanks for another great order!

Nice item

Pros: insulation is not ridiculously thick.

Cons: None.

I bought this to wire my car, works well, no issues. I found the insulation to be a good size and have experienced other wire of the same gauge to have thicker insulation.
