Absolute polarity is quite audible, Bill. But one has to train their ears, like any other sensory skill. I'm not ashamed to say that it took me a decade of listening to be able to recognize it.
Polarity is more easily identifiable in wind instruments and voices. Tongued attacks will sound like a breath attack. Consonants loose their crispness (consider the difference between voicing a P and a B). Generally speaking, I find that whenever a video buff moans about the fact that his effects are drowning out the dialogue, the soundtrack is reversed. In fact more often than not, when the significant other yells that the TV is too loud, the chances are the programming is likewise reversed in polarity, making the dialogue sound like everyone's slightly mumbling and hence the need for more volume.
Other audible clues, since many waveforms are asymmetrical, are a slightly louder volume when in correct polarity.
All this, assuming the speakers used are phased correctly. Since all too many speakers have drivers in mixed polarity, the test or a switch in polarities will often result in a mixed reaction. Of course many record producers deliberately mix polarities in order to achieve certain effects, but that is another issue.
Actually, I'm a bit surprised that you bring this up. Early QSC amps, the series 1, which I liked very much, BTW, had their 1/4 inch jack inputs inverted to the terminal strips. I was told this was done to protect the speakers from blowing out if the jacks were accidentally pulled out while the amp was running. The speaker cone would move backward and bottom out, rather outward and ripping the VC wires out. I guess, commercially, bad sound is better than no sound.
