Speaker wires are electrical cables designed to connect audio speakers to an amplifier or receiver. They carry audio signals from the source to the speakers, allowing sound to be produced. Typically made of copper, these wires come in various gauges, with lower numbers indicating thicker wires that can carry more power. The quality of speaker wires can affect sound performance, especially in high-fidelity audio systems. Properly selecting the right gauge and length helps minimize signal loss and ensures clear sound reproduction. Additionally, speaker wires may be insulated to protect against interference and damage, enhancing overall audio quality.
