If I use an RTA or FFT analyzer I can see that there is no real
change excpect for a brief transient during polarity switch. With the
FFT you can see the level of each individualfrequency component and
none of them change.

So that proves that nothing has changed but the polarity, yet you hear
hear the change. Hence you an hear a difference between normal and
inverted polarity. QED

The quick FFT test proves that there is no change except polarity in
the ELECTRICAL signal fed to the speakers. It says nothing about the
sound signal comming out of the speakers. I'll need to set up a mic
for that test and get back to you.


Any change you hear is due to phase errors in your speakers and is
totaly random.

Uh . . . . out of which monkey's ass did you pull this "fact?"


Becasue I obtained different results by moving my head. One time the
first polarity appeared to have more bass, the next time the second
polarity appeared to have more bass. The only change was my
position. In some cases there was no perceptible change. Therefore
the use of the term random.

Have you tried it on headphones?

No I will get back to you.
