| Speaker Wire |
 |
| Speaker wire is used to make the electrical connection between loudspeakers and audio amplifiers. Modern speaker wire consists of two electrical conductors individually insulated by plastic. Both a positive and a negative conductor are provided. Certain older designs also featured another pair of wires for a powered line to power an electromagnet in the loudspeaker before permanent magnets became economical to produce and use. |
