Choice™ Series 12AWG 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: Nice and heavy for long run. Not too stiff.

Cons: none

This is what I need for a long run to surround speakers.

Nice product

Pros: The price is great, the cable seems to be great quality, and the insulation is nice and thick.

Cons: None so far

Although I've only had this speaker wire for a short time, it seems to be doing very well and exceeds my needs. Honestly this is a much larger gauge wire than I need, but who cares, it works! The clear insulation is thick so you don't have to worry about the copper being damaged easily.

Not bad, but oxidizes heavily

I purchased this cable to run my entire HT set up years ago and within a year or 2 the cables are totally oxidized and a blackish green color as you can see through the clear sheath. This makes it difficult when you have to strip an end and make a new connection as you have to clean the cable ends very well. I use salt and vinegar followed by water and baking soda to help clean the ends. I am looking into something to put on the end to maintain the electrical connection. This is a chemical reaction with the plastic liner and the copper, but they could have used something less reactive. When I ran out I found some other cable locally and that has not tarnished or oxidized one bit in over 12 years. In this case you get what you pay for. Unfortunately all the surrounds and rears are now buried in walls and ceilings so swapping out is not an options. Event the cable runs not in wall have oxidized, has to do with whatever material the sheathing is made from reacting with the copper.

Thank you for your review on PID 2789. I am truly sorry to hear about the issues experienced with this speaker wire. Just to verify, is the wire only oxidized on the tips or does it appear to be an issue throughout the whole wire? Were the parts that are oxidized exposed to the air? Please let me know so we can look into this matter further. Thank you in advance!

The entire run of the cable has fully oxidized over the years, all runs. My understanding is that it will have no impact on signal quality, but does make it hard when you have to cut back and to get new connections and have to try and clean the cable. I have other cables that over 12 years have never oxidized anywhere. The material used in the sheath of your cable is reacting with the copper cable.

I completely understand. I will submit a complaint regarding this for our product team to take into consideration. Unfortunately, it sounds as though you may have received a defective product as this is not a common occurrence that we see with our speaker cable. I truly apologize for any inconvenience this may have caused. I also wanted to note that we would be able to replace it as we cover our cables with a lifetime warranty, although we would need the cables sent back to us before we are able to send out the replacement. I understand this is problematic as you have the cable ran in-wall currently, however if you would like to proceed with the replacement, please feel free to let me know and I would be happy to help. Thank you very much for your time and feedback!

Thanks, but it is more a cosmetic issue an you are correct, the cables are inaccessible now so I will live with it unless they become an issue in the future.

Pros: Great product - strong, thick coating, great price.

Cons: This is slightly thicker coating than some speaker wire - just beware if trying to fit in certain areas / conduit.

Great product - great price!
