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.
Questions and Answers
That said, IF it does have a lower impedance the difference would be insignificant at best (likely inaudible outside of soundproof lab conditions) The more important thing is to get a wire that is appropriately sized and up to any applicable codes for your application, like fire rated, and I would suggest oxygen-free pure copper, because clad aluminum will have a higher impedance and be more likely to change the sound.
One is good quality copper wire which does everything you would think speaker wire should (transmit electrical impulses with adequate current and low resistance). That is exactly what this wire does. For good quality copper wire, you can buy it here, or pay a lot more if you like it to have fancy colored insulation or a brand name (you know, the things that go bump in the night). 12 gauge is thick enough for about everyone (exceptions would maybe include high current electrostatic speakers or the like).
The other kind of speaker wire is the high-end exotics which can often go for hundreds to even thousands of dollars (yes, it's true). If these are for you, get off this site and go down to your local high-end audio store.
For me (and probably you) this wire is probably as good as you will get at any big box or hardware store at a better price.
Sound is exactly what I expected and my audio measurements are perfectly symmetrical the speaker wire is everything that I expected for the money. This speaker wire does not have the marketing machine behind it that Monster cable has you can expect superior performance from this cable than a Monster cable product, just not as nice packaging.
If you need to run long distances with the wire and you want to future-proof your installation, this is suitable wire. It can handle much more current than I will ever pump through it (my Prismas can handle 500W sustained... but neither my amp nor my ears can). I have no reservations recommending this wire for a high performance media room.
PROS: Obvious polarity marking
Flexible for 12 gauge
Fine individual strands
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.
As for the 12AWG. My references say the 99 ft (looped back) should have a resistance of 0.0795 ohms. Mine measures 0.982 - so it's somehwhere between 12 and 14 AWG.
The 14 AWG I bought from Phillips measures 0.1273 (should be .1262) so my metering seems right.
So It's "ok" but not premium.
PROS: Nice and thick wire with thick insulation
CONS: The insulation would not fit into the monoprice closed screw type banana plugs (PID 2801), so you either have to strip the insulation back the entire length of the plug (plus what's necessary to make the banana plug connection) or you have to shave down the insulation.
PROS: Good quality, price
