100ft 14/4 White Speaker Cable, CM,Stranded CopperProduct Filters
Our speaker wire is made from pure copper. Some companies use the marketing term oxygen free copper which really means there is no iron oxide in the wire. When oxides of iron are in the copper, the conductivity of the wire reduces due to the higher resistance of the iron oxide. So it is in your best interest to install speaker wire made with pure copper like ours are. Another misnomer is that copper clad aluminum is the same quality as pure copper; this is false. The resistance (Ohms) between the two differ and as resistance in the cable increases the power delivered to the speaker is reduced. The sound will be lower and can lose some of its quality. If copper's conductivity, due to resistance, is rated at 100% then aluminum's conductivity would be rated at 61%. In order to deliver the same quality of sound with aluminum one would need a much larger gauge.

Feels and looks of quality made. not copper Clad. Very well insulated. I will purchase again in the future.

This cable gives a much better bass response as compared to my old narrow-gage speaker wires which I have thrown away.
