Default Measuring Speaker Impedance

For reference...
Since you CANNOT take a multimeter and measure any speaker's impedance (4 ohms, 8 ohms etc.) with it, I'm including some info on how to do it, or how it's normally done.
The multimeter method will only give you the speaker's resistance at DC, and we know DC has little to do with music frequencies of 20Hz-20kHz. The true impedance is an average measurement of the speaker's impedance across the whole frequency range.
