Listening Question: Would a high frequency square wave sound the same as a sine wave?

[davidsrsb]

Tweeters have a habit of generating sub-harmonics when they go into break up with a single tone. This is not intermodulation.

I know how to do #1 on the list. How do you achieve #2?

maybe:

• an O-scope
• a high frequency IM test
• measure signal-to-noise ratio
