The basic information of Speaker Wire
From Wiki:”Speaker wire is used to make the electrical connection between loudspeakers and audio amplifiers. Modern speaker wire consists of two or more electrical conductors individually insulated by plastic (such as PVC, PE or Teflon) or, less commonly, rubber”.The two wires are the same,but they are marked by colors to identify the correct audio signal polarity.However,some of the speaker wires endowed with a 2nd plastic jacket to more totally against kinks and cuts;and it also much easier to pull wire behind walls or ceilings.
Selecting Speaker Wire
The quality of speaker wire are vary from brand to brand;range from the quality of the jacketing to the purity of the typically copper.the quality copper wire means the quality conductive properties. While, there are some jackets that less reactive to the interior conductor, it is easier to pull through walls and ceilings for industrial applications.One thing needs to mention is the resistance of the wire.If the wire’s resistance too high,it will cause an audible problem on audio when transfer.Therefore,Only when you use a thicker wire gauge,can you guarantee a lower resistance.
