Re: New Lightweight Power Amp Ratings
JR,
What would you think about a measurement method that integrates the total amount of joules of energy from an amp over a long period of time at different frequencies?
For instance, Integrate the total number of joules of energy from an amp at 1 frequency (20k) at 100% output voltage for a period of 8 hours at its lowest stable impedance, say 1.8ohms per channel. Then compare that with the same amp with the same load and same level at 19khz, then 18 etc. THEN, integrate the total amount of energy from all frequencies at max voltage and lowest impedance to arrive at the absolute max amount of energy that this amp can source at a show. Then, to be fair to current limited amps, perform all of those calculations at all useful impedances from 1ohm to 16ohms. Then integrate those results. For the truly anal, one could further perform all of these calculations again at different line voltages.
I think only then will anyone be able to tell with any certainty that amp A actually has more power capability that amp B.
In my mind this would unveil which amps truly have the thermal capability advertised and which amps are nothing more than marketing in a box.
