In Reply to: RE: A funny story about square wave test on speakers posted by beppe61 on December 13, 2014 at 23:34:18
Its a good question. :)
I'm not sure I see a value in square wave testing of speakers. Square waves are inherently dangerous to speaker coils causing excessive heat build up in windings. One can easily damage their speaker with a square wave test. I would recommend against it.
However, I'm all for square wave testing an amplifier. It gives a good indication of an ampifier's transient response.

Hi and thanks a lot for the valuable advice
I have been convinced that is not a reasonable test
I still think that some kind of instrumental test could be correlate with sound quality and now i think more to distortion measurements
I remember at least one case of a speaker with a response curve very up and down but with a well judged sound
Maybe the distortion was low ?
Thanks again.
Kind regards,

The good news is you don't need to test using square waves. You can obtain impulse response or step response using the requisite measurement software.
Cheers,
Presto
