RE: Why is inverting or non-inverting important?

Posted by Hornlover on June 7, 2017 at 08:53:54:
There are some situations where you can indeed tell a difference. Try playing a good recording of a kick drum (which in the real world will cause an initial compression). Try it both in proper phase (woofer cones compress on initial attack), and then reverse the speaker leads, so the initial attack is a refraction. You can tell the difference. I did a lot of investigation on this years ago using the Sheffield Labs drum record. My audiophile buddies could hear it too, so its not just me. You need a scope to make sure what polarity you are sending to the loudspeakers. Because of this, I still make sure my final polarity at the loudspeakers is proper. Various recordings may be all over the place, but at least I know that if I send a positive pulse into my preamp, I get a positive pulse to my loudspeakers.
