Speaker Cables

Speaker cables are high-current audio cables designed to carry amplified signals from an amplifier to loudspeakers. Unlike interconnect cables, which transmit low-level signals between source components, speaker cables handle significantly higher power levels and must maintain low resistance to preserve signal integrity. Correctly specified speaker cables ensure efficient power transfer and consistent performance across a wide range of speaker and amplifier combinations.

Speaker Cables for Amplifier-to-Speaker Connections

Speaker cables are used exclusively between power amplifiers and speakers, where the audio signal has already been amplified to speaker level. Cable construction, conductor gauge and termination type all influence how effectively power is delivered to the speaker terminals, particularly with longer cable runs or low-impedance speakers. For connections between source components such as DACs or CD players, line-level RCA cables are used instead, as speaker cables are not suitable for low-level audio signals.

Many speaker cables are available in single-wire and bi-wire configurations. Single-wire cables connect one amplifier output to one set of speaker terminals, while bi-wire designs separate high- and low-frequency signal paths when used with compatible speakers. Choosing the correct configuration depends on the speaker design and amplifier output options rather than cable preference alone.
