Speaker V vs. I Plot - Caroline Deleted - Portal 2

This is an XY plot of current (X-axis) vs. voltage (Y-axis) for a run-of-the-mill bookshelf speaker. Yes, I know the axes are backwards from a conventional IV plot.

Speakers are far from ideal loads, especially when they contain passive crossovers. An ideal speaker would have a line with a constant slope that elongated out from the middle.

The displayed oscilloscope is my Tektronix 7854. I used a current probe to measure the current in the speaker leads, and a conventional X10 oscilloscope probe for the voltage.
