Kõlarijuhtmed, also known as speaker cables, are electrical cables that connect a loudspeaker to an amplifier or receiver. Their primary function is to transmit the audio signal from the amplifier to the speaker drivers, which then convert this electrical signal into sound waves. The quality and type of speaker cable can influence the fidelity of the sound reproduction, though the impact is often debated among audiophiles.

Speaker cables are typically made of copper, though other conductive materials like silver or aluminum can be used. The thickness of the cable, often measured in gauge (AWG), is an important factor. Thicker cables (lower AWG number) generally have lower resistance, which can be beneficial for longer cable runs or for driving demanding speakers, as it reduces signal loss and potential distortion. The construction of the cable, including the insulation material and any shielding, can also affect its performance by minimizing electromagnetic interference.

When selecting speaker cables, consideration should be given to the intended use, the length of the run, and the impedance of the speakers. Most common speaker cables are made of two conductors, one for the positive signal and one for the negative. These are often color-coded or marked to ensure correct polarity when connecting to both the amplifier and the speaker, as incorrect polarity can lead to phase cancellation and degraded sound quality. Standard connectors, such as banana plugs or spade connectors, are often used at the ends of the cables for secure and easy connections.
