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.

great quality speaker wirePosted on 6/2/2012 Generally, speaker wire is not the hot item in your audio system, until you use one that really affect your sound, or makes it a challenge to install, use, or otherwise appreciate. I was impressed with Aperion's speaker wire. I just wish they'd offer a bigger spool as an option (200 feet, perhaps?) Highly recommended.
Well DonePosted on 6/2/2012 Note: This review was written when we were out of stock on the Aperion-branded wire and substituting a comparable brand of wire.
Would have preferred the Aperion brand, but measured resistance on this substitute was negligable. Have used the stuff from Home Deport in the past. $80/100ft, turns green in six months and the negative lead is aluminum (learining process). Have also used silver cable which is entirely too expensive for the benefit returned. This stuff is a bargain. I was thoroughly disappointed that it wasn't packed in a blue velvet bag like the amazing speaker systems. No confetti either, just peanuts. Aperion has my highest praise for quality and service.
Good speaker wirePosted on 6/2/2012 Make sure you get the most out of your speakers - don't skimp on wiring. This stuff is quality wire and gets the job done.
