Need a MultiTone test based on actual music

[voodooless]

It is an unrealistic level for tweeters in music conditions.

Sure, it is. But then you just pick a lower level And obviously, the multi-tone is a worst-case experiment.

For the same reason (but arguably there is a lot more power then) one tests speakers or adjusts EQ using pink noise and not white noise.
White noise at high levels also isn't particularly pleasant to be around the same goes for multitone at high levels.

You don't do these tests to listen to them

Yes, for testing at 5W the regular multitone is fine (tweeter would see around 0.5W).
Would not recommend to test multitone with speakers near full power in >50W amps though as that tone is continuous where music isn't.

Obviously not

For me multitone with equal levels on all frequencies is good to measure amplifiers to their limit. If good in the high region then the amp will be better when the music high content is less in level what it is in regualar music. Loudspeaker tests with multitone were also done by testers but I assume at lower levels. If testing needed to get the compression limits of a loudspeaker them M-Noise from Meyer PA can be used.

JAS - suggest track down their test tone cd developed for testing aspects of audio gear performance
