Yes Agree,
SW testing of speakers is a valid test , but not "the" test, just one of many tools available to a designer. A perfect SW does not mean one product is superior than another it's the balance of all accumulated measurements which discerns this ..

What do you hope to measure with a square wave test on a speaker? A square wave is not the same as an impulse response.
A square wave is not linear at all so using this to test a loudspeaker is pointless not to mention damaging to the voice call.
So good SW response signals nothing ? bad SW response signals nothing ..? what about speakers with no VC to damage ... ?
Yep, a square wave test is useless in speaker testing. You get far more information from an impulse response.
@3db,
Not impulse, Step response .....

"What do you hope to measure with a square wave test on a speaker?"
Why not?
You can tell a lot about hopefully linear systems using a squarewave and a scope. It has nothing to do with music, it's just a "test signal" that's easy to generate and observe and, IMHO, typically very revealing.
But I can't say that I've ever tried it on speakers and I can see where it would be a lot more ackward than using the technique in the electrical realm.

Hi and thanks a lot for your valuable advice
After the discussion i am not so sure that the test actually correlates well with sound quality
I guess it tells something about the "dynamic" abilities of the speaker/driver under test
But reading around i have come to the conclusion that some kind of distortion measurement is THE test that is more likely to be correlate with the actual sound quality of a speaker
So i think that good sound could imply low distortion
This is also important i think.
I am always more interested in objective test than subjective.
Usually i like what people like.
Thanks again.
Kind regards,

Hello,
It's more the avg of all test results than picking anyone in particular, i do believe a good SW response tells alot , not the whole story...
Regards
Hi and thanks again
+1 for the SW response test then !
And after ? which do you think could be another "telling" test for sound quality test ?
In my ideal world you put on a cd with a series of well designed signals you measure the response and at the end you get a rating of the sound quality of a speaker
I like so much things when they are objectives. Very much.
Thanks again.
Kind regards,
