2. Speaker wire - Wikipedia

   en.wikipedia.org/wiki/Speaker_wire

   The voltage on a speaker wire depends on amplifier power; for a 100-watt-per-channel amplifier, the voltage will be about 30 volts RMS. At such voltage, a 1 percent loss will occur at 3,000 ohms or less of capacitive reactance.

3. Constant-voltage speaker system - Wikipedia

   en.wikipedia.org/wiki/Constant-voltage_speaker...

   Special-purpose transformers capable of handling 1250 watts down as low as 50 Hz are available. One problem with high power, high current transformers is that fewer can be used on a single constant-voltage line. Larger diameter speaker wire is recommended. Larger transformers needed for high power handling have reduced high-frequency response.

7. American wire gauge - Wikipedia

   en.wikipedia.org/wiki/American_wire_gauge

   American Wire Gauge ( AWG) is a logarithmic stepped standardized wire gauge system used since 1857, predominantly in North America, for the diameters of round, solid, nonferrous, electrically conducting wire. Dimensions of the wires are given in ASTM standard B 258. [1] The cross-sectional area of each gauge is an important factor for ...
