Dave…..I have debunked this theory countless times with pairs of matched drivers out of the box that are still matched after one has been played for a week and the other just unboxed. Are you suggesting the DDR thing is at play here again? All I’ve ever done before measuring is exercise the suspension half a dozen times and that’s it.
Now I’ll give you your theory where planar (folded) tweeters are concerned……they do change response behavior over time and I’ve seen impedance peaks reduced by 10/15% in some cases……but NEVER in a cone driver with anything but a foam surround ( we know what happens there in a few years)

And my experience is the opposite. T/S numbers are essentially the same, but the drivers sound different.

May I offer my ultimate L/R comp: play the same track twice, in between quickly swap the channels into the amp; if L/R half of the soundstage always sounded better then that driver or XO won.
Ok so that’s just the parking spot right?…….that’s not where they are when you’re playing them?
