"You" is FTC's lawyer (or someone acting as one -
@JustJones , for example).
If amplifier manufacturer tested their amplifier with only 4 frequencies (20Hz, 1 kHz, 6.6 kHz and 20 kHz) for 5 minutes at each frequency and find these power output (at 8 ohm), for example:
100W@20Hz, 150W@1kHz,
[email protected] and 80W @20kHz, with no more than 1% THD,
than they may freely advertise their amplifier to be FTC compliant, because they
don't lie about those measured numbers.
But if FTC or
@JustJones try to sue that manufacturer (requesting testing with "all frequencies in 20Hz-20kHz range"), they will fail spectacularly at the court - even the stupidest judge know that there is infinite number of frequencies at that range (or any range), so it will impossible for anyone to do that.
Of course, the easiest way is FTC to change the nonsense "all frequencies" with something logical.
