In my old life;
We pulsed RF, after pulse, wait Xtime, sample

Guessing that is NOT? What’s going on with NOTE(*)  Musical power

Thanks

It is shameful to call this "Music" power.

This is Totally clipped-out SQUARE Wave power.

It might be a guide for picking a speaker's true dissipation capacity in a party-box or guitar amplifier, where distortion is part of the job. 

For pre-made music, the 70 Watts is the number to compare.

Totally clipped-out

Ya, there's a note about non-linearity 
I'm looking for 50Wrms, appears it gets there

So it's a continuous "...wave", sample at 1 second VS one wave, wait 1 second sample 

thanks as always

Their BS test is to run it up to FULL! power, totally clipped. This could kick-in protection circuits, so they wait one second for that to happen. Then they take a reading.

It is plausibly a meaningful test for BOOM boxes which might clip hard a part-second every few seconds, and the users tolerate gross distortion.

It may not be meaningful for headbanger solid-clipping guitar amplification, where a clip may last bars, not just a second.

Since it has an IEC number I suppose other makers do the same test and you can compare them.

I think the "standard" SPL testing has undergone changes also since I last looked (20yrs ago :)
I see a lot of 2.83v @ 1meter instead of the old 1v @ 1 meter and what do you know, the SPL value is higher at 2.83_duh!

thanks for the time PRR, always appreciated.
I'm just looking for 50W max clean, 30-40w probably good enough, so far 2 channel board-kit is under $25, reasonable, the PS + good filtering is still near $75 so I'm in scrounge mode there
