The way we created impedance curves with our analog Brule & Kjaer equipment was to put 10 volts of audio from a power amp through a 1000 ohm resistor, then to the speaker. 1 ohm of speaker impedance would have roughly 10 mv of signal across it. 8 ohms, 80 millivolts. (A power amp and an ac meter capable of resolving millivolts were required for this.)
Why not just use a 1 Ohm resistor and 1V of signal?
