Speaker Wire Guide: How To Choose The Right Gauge

Speaker wires are intended to transfer the signal and energy from the audio amplifiers to the speakers, hence their name. Speaker wires differ in material, construction, thickness, and a few other features which can be rather different.

Speaker wire consists of two or sometimes more identical electrical conductors with different markings in order to identify themselves more easily. Correctly sized speaker wire has very little effect on the audio signal quality despite the claims by some wire manufacturers which often use technical terms like "skin effect", "impedance", "resonance", etc. in order to confuse and impress end users.
