By all means please show the do’s in Class-D, hopefully independently
tested, impedance v rms wattage all at just before clipping into 8, 4
and 2ohms, the same distortion figures.
Ha! That's pretty funny!
**No** amplifier will have the same distortion figures. All amps regardless of technology used have higher distortion into lower impedances. This has been seen over and over again in tests by JA at Stereophile, Bascomb King and others all over the world.
And right here might be the simple salient fact to the pointlessness of the inquiry: If you want the best results from your amplifier investment dollar, that dollar will be best served by a speaker load of higher impedance ***IF HIGH QUALITY SOUND IS YOUR GOAL***. (Sorry about the caps- I was looking for emphasis, not shouting). This is where that magical line in the sand occurs- the difference between the results sounding like real music or just a really good hifi.
Plain and simple low impedance speaker loads are a Bad Idea and it doesn't matter if you can weld with your amplifier- it simply will make more distortion into that lower impedance, and that distortion will be audible as less detail and harsher. Doesn't matter if the amp can double power or not- the higher distortion will be there nonetheless. Again- its easy to see in the specs and independent measurement.
The story of Sisyphus is there as a teaching moment and applies directly to the the task of driving lower impedances.
