Output volume is unarguably related to I^2R. With my DVM I measure typical AC voltages of 5-6 volts at speaker terminals when playing loud. However this meter does not have the temporal response to read accurate values for the peaks, so let me get back to you on that once I have a decent analog AC Voltmeter to play with.
My unfounded belief is that much of this preoccupation with massive power is a reflection of the amplifier architecture required by low impedance speakers. A power supply that can readily provide the current required is feature of a better quality amp. The degradation in sound quality that one might hear from lower power amplifiers may be the impact of shortfalls in the power supply dept.
My expectation is that at `my volumes' there are peaks to perhaps +/-20V, and potentially the impedance of planar may be as low as 2.5 Ohms. This suggests an F5 with a power supply that can give 40V/2.5 Ohms (16A) might do the trick.
However, my wife tells me that on occasion I am wrong.
