In Reply to: RE: Can a square wave test tell something about a speaker ? posted by beppe61 on April 23, 2014 at 00:45:16
The only thing the square-wave is going to tell when it's monitoring the amp at the speaker load connections is that the speaker has more of a stable load,most likely resistive if the square-wave looks half way decent.
Honest amplification is better than excessive 2nd order distortion anytime.

Hi and thanks for the valuable reply
But i am more interested in speakers response to a square wave
My feeling is that most electronics when the load is not particularly demanding can give a good square wave at the ouptut.
Instead to get a good square wave from a speaker is quite a task
I am trying to understand if this is important.
For instance many crossovers deform already a square wave.
I listened to the speaker i mention and like the sound a lot especially in the midrange, a range that interests me very much indeed.
I do not know if this can be related in some way to the great performance in the square wave test.
Thanks again and kind regards, beppe

This may help.
Hi and thanks for the kind and interesting advice
I am afraid the article is too difficult for me to understand
When there is math i am quite lostNevertheless the idea to establish an instrumental method that can be used to assess objectively the fidelity of a speaker intrigues me a lot.
This square wave test seems quite easy to carry out.
You have just to send square waves with different frequencies in the amp an put a microfone connected to a scope in front of the speaker and see on the scope.
My problem is that i do not know how indicative it can be.
My feeling is a lot indeed, even if the signal is very different from a musical signal.
I also notice that is very rare and the options are two:
1) it is not telling anything
3) it is telling something
Thanks again and kind regards,
