Review on Cmple 14Awg Jacket Compact Speaker by Nate Forleo

Although this wire is described as 'specially engineered, high purity, oxygen-free copper wire', this wire is actually aluminum which cannot be soldered with traditional solder and its resistance is 64% higher than copper. The cable will look like the one shown in the picture and may consist of two insulated wires, one copper and one tinned copper, to distinguish between the polarity matching terminals in the speakers. However, when I tried soldering banana plugs to my speakers and amp, I found that the copper-colored wire is aluminum with a thin layer of copper that immediately scratches, while the wire that looks like tinned copper is all aluminum. Please note that this item is not from Revain, it is 'shipped and sold by Cmple'. If you have any questions, please contact Cmple. I have attempted to contact them via email and phone to replace my order with the advertised "14 gauge high purity oxygen free copper wire" or to refund my purchase price but they have not yet responded to either communication. I don't know if their Chinese supplier substituted materials with them without permission or if they are part of this scam, but save yourself the heartache and order cables from another supplier to have the material (copper) and performance (low resistance ) to get you pay. . Having looked at this in more detail, 16-gauge copper wire has a lower resistance than 14-gauge aluminum, 14-gauge copper wire has a lower resistance than 12-gauge aluminum, and 12-gauge copper wire has a lower resistance than 10 gauge aluminum - stick with copper For better performance and avoiding contact problems that aluminum can cause.
