1khz is the industry standard to test equipment at, it's what I bench test at- sine and square if I really want to hammer it.
Industry standards are not 1 kHz , my friend.
Never been , never will be. It's a way of specifying machines , that need some push to be specified.
No one takes measurements at din standards , not now not ever. That's a 1khz test tone to check power amp's output . It shows a bit more output than the classic 20hz to 20khz measurement.
If you really want to hammer it try a 50 hz sine wave , and if you want to be really bad make that a square .
