Hi
To my experience the gain of an amplifier depends on the loudspeaker impedance...
Noooo... I do not have a gazillion$ measurement system, and a trackrecord of 100 amplifier/speaker combinations
BUT, I detect an increase in output sine voltage depending on impedance of the loudspeaker, most obvious around impedance peaks. It would be in the order of a few dB...
I search the web and all I find are these simple "calculators" where you compare "8 ohm" speakers with "4 ohm"...
Does anyone here know of measurements of amplifier frequency responce over fex a "dummy load" emulating a complex loudspeaker impedance?
I know the Swedish "Audio Engineering Society" use a dummy load to test amplifiers if they are "transparent" "before-after-test".
But... measurement results of frequency responce over a dummy load?
