It is easily detected if a single full-range speaker is used for testing, same with 2-way speakers that X-over above 1kHz, same with speakers that emplay bass and midrange drivers of equal polarity. A single (mono) speaker will be located coherently (the sound sticks to the speaker) at correct polarity, while polarity reversal diffuses the sound and it appears bigger, wider than the speaker but less forward, less focussed. <br />Playing music from harddisc gives the opportunity to correct polarity (SoX, WAV-editors)and store a correct polarity. Classical music require polarity reversal in 90% of all files, Pop and Jazz 40%. As modern studios supply correct polarity. It should be self-understood, but the archaic companies stick to their tradition (I know recorings that were correct in origin, but mastering polarity reversed them).<br />I am a passionate avocate of polarity correction, I agree with George S. Louis in many aspects but not in all.<br />With inverted polarity I sometimes have a strange pressure on my ears when I enter the listening room. I have observed many aspects that change with switching polarity and confirm that listening for best polarity can become obsessive.

Its really silly to argue over a factor that depends upon a speaker that plays all frequencies moving in harmony. To me, reverse polarity is like what happens when looking through binoculars from the wrong end. Not as magnified in effect, but the image is either moving you into the music, or pulls you away. Its a silly argument for those hear what is obvious to them. I use Audience 1+1 speakers. You can not get more phase coherent than that. And, it was always obvious on any speaker I listened to with a first order crossover. Many speakers wire the tweeter 180 degrees out of phase with the mid-woofer.

I took the trouble to mark each jewel case with a zero or inverted insignia. Then my transport died after 12 years. The new transport is apparently of opposite polarity (unless it's the way its American XLR mates with the British DAC) because all the discs now sound better the other way. Maybe it's just some sonic effect that the switch circuitry has and isn't polarity at all, but it is interesting that it's now reversed.

It might be that in some systems where the tweeters and mid/woofers at the crossover are wired out of phase to begin with, that testing may be a bit of a problem. Best, it requires a phase coherent speaker to begin with. Now, if you have a phase coherent system? Then I wonder why it can not be detected. I am a musician and can readily hear a difference on a system with a 1st order crossover. If the subwoofer is out of polarity with the main speakers, that also may cause a blurring of what's to be looked for. Unknownhttps://www.blogger.com/profile/07023220411528202633noreply@blogger.com
