    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.

    Cons: nothing is bad for met at least monoprice has anoter great product here highyly recomended.

    I have shopped at monoprice for many years now for my cables and and audio products ,once again monoprice continues to sell quality products at a great price! I bought the 100 ft .AWG 12 guage speaker wire ,and hooked up to my 5.2.2 surround sound speakers and i couldnt be happier !,The sound is pristene and clear,and i dont get listener fatigue like i use to(I like to listen to music 6 hours or more at a time ) I cant wait to get my new dolby atmos dtxx av receiver to enjoy my blu ray movies!this 12 guage wire is a great investment in my home theate sysem and it should also be used in yours!!

    Amazing Sound

    Pros: Solid copper, polarity marking.

    Cons: none

    I'm not a real audiophile( I couldn't even play one on TV), but I can certainly hear the difference that this 12 AWG copper wire has made to my system. I have a lovely set of JBL 15" horns that were not getting their due with the light gauge wire. Now they're happy, and I'm happy! Thanks!

    Pros: Good quality. Good price

    Cons: none

    Quick shipping. First thing I notice is how thick the jacket is. Very flexible for heavy gauge wire

    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.
