[QUOTE="Max Warasila, post: 209464, member: 3845"] I in fact have two of these drivers, both of which measure within an ohm of each other. I went into my university’s lab and finally got a reasonable seeming result by using a voltage divider to determine the resistance of the circuit. In all honesty, even the test bench DMM did a poor job of measuring driver and resistor resistances. Not really sure as to why. At any rate, I found them both to be hovering around 5.1 ohms, which is closer to reality, I’d hope. This was done at about half a volt for the entire circuit. Similar results were found at 1 volt. I still need to figure out what is wrong with my free air impedance measurements. [/QUOTE]
