I may be overthinking this -
I have been lucky enough to own a pair of Kef 104/2 speakers for the last 30 years. About 10 years ago, I noticed that they didn't really seem to be as good as they had been and on inspecting what Audyssey was trying to do to correct them, realized that the tweeters were toast - dried up ferrofluid.
So, I duly replaced the tweeters with mdt29 tweeters, paying careful attention to the wiring. Absolutely astonishing improvement! It is amazing what you get used to in your own little audio bubble.
Every so often, I run Audyssey calibration to see what is going on and correct for changes in room acoustics. It tended to complain about a speaker being out of phase and I tended to ignore it.
I ran these tests - https://www.audiocheck.net/audiotests_polaritycheck.php and it seemed that the Audyssey might be right.
I used Speaker Pop to test polarity more precisely on each driver (well, at the bass port in the case of the woofers) - https://studiosixdigital.com/audiotools-modules-2/speaker-test-modules/speaker_pop/
Indeed, the tweeters were out of phase with the other drivers. So I reversed their wires and they are now in-phase with everything. And sound better? But that is subjective and not blind or dispassionate testing.
Now I read that more complex passive crossovers may well reverse driver polarity and so those drivers should be connected to the crossover in reverse polarity.
But does this not correct the driver so that it will perform in-phase with the other drivers? Isn't the bottom line what happens to the air that the speaker units are moving and nothing else?
So I have a pair of Kefs which, to my ears, sound pretty good with excellent imaging. Am I doing something wrong by having the tweeters in-phase even though they are connected (apparently) incorrectly?
I'll welcome any corrections to my thinking.
