Georgehifi,
You are correct. I have limited technical understanding of EPDR. I understand that a loudspeaker is not a resistive load. It is reactive and the reactance varies with frequency, as the phase angle varies with frequency. And the phase angle is the sine wave angular offset between the voltage and the current waveforms at the given frequency. I have no idea how to calculate EPDR, however.
Nevertheless, using the data from KH, can I assume that the amplifier current draw at 92 Hz will be approximately equivalent to the current draw, for the same signal (voltage) level, into a purely resistive load of 1.30 ohms?Just trying to understand these measurements a little better. I think I have already determined how to select an amplifier for these particular loudspeakers.
Charles, George, and other contributors,
Thanks for your inputs. They were informative and useful.
