In Reply to: A funny story about square wave test on speakers posted by beppe61 on December 13, 2014 at 23:34:18:
I don't know about who dismissed it, but the square wave test has been used as a speaker test for years - most of the time it looks not very much like a square wave, though by how it reproduces it, might give some ideas about driver integration, time and phase alignment.
I know the Quad ESL63 and later models based on the same, used the near perfect reproduction of the square wave as marketing for their speaker's accuracy.
I pasted, above, first the Stereophile measurement showing the Quad ESL63
Most speakers do not show something this well. I think many show the impulse test since you can see how well phase/time aligned the speaker might be.
