For example, if a 4 ohm resistor was connected in series with a nominally 4 ohm speaker, the resistor and speaker would divide the voltage equally at a frequency where the speaker resistance actually was 4 ohms. In practice, speakers can vary widely in impedance as the frequency varies.
John, this is correct, a 4ohm+4ohm load in seres would be 8ohms, and would be the reference point. As the speaker's impedance varied up or down, it would vary the same amount, and the over all circuits resistance would vary in line with the speakers impedance.
Andrew, are you talking about the voltage loss across the resistor? So, the voltage loss across the resistor would alter the voltage seen at the driver, which would skew the impedance graph?
It's been a couple years since i have done KVL's or KCL's so please bear with me.. But this seems more like a KVL problem, at a static point, the more i think about it...
I should be working on applied regression... But no.... gr
