American wire gauge (AWG) is a system of numerical designations of wire ... For example, it would take nearly 1 ohm of cable resistance to drop the signal level down 1dB for an 8 ohm speaker. More ...

To put it bluntly, a thinner gauge wire over an extended length will introduce its own significant amount of impedance (50 feet of 24 AWG wire calculates to be 2.62 ohms, for example). When you're ...

The best speaker wires come in various gauges; as the AWG (American Wire Gauge) number decreases, the size of the wire increases. For example, a 12 AWG wire is bigger than an 18 AWG wire.
