Speaker cables are electrical wires that connect audio speakers to an amplifier or receiver. They carry audio signals from the source to the speakers, allowing sound to be produced. The quality of these cables can affect sound clarity and performance, making it important to choose the right type for your audio system. Typically made of copper or other conductive materials, speaker cables come in various gauges, which indicate their thickness. Thicker cables can carry more power and are often preferred for longer distances. Properly connecting speaker cables ensures optimal sound quality and prevents signal loss.
