Thanks for the measurements Johnsonad. It confirms my thought that the original inductors probably weren't what the schematic claims them to be.
You didn't say if the new inductors sounded much better to you but I assume they do if your still using them and your happy with the sound.
Hard to say if they all fall into where yours and mine do unless more people post measurements.
But now to ask another question, I wonder if that was on purpose or just a function of tolerance/cost effectiveness in the manufacturing process?
With no other change other than the 2.7 inductors, I went from very listenable to annoying tonal balance with new inductors that read 2.7 on the money and not all that less in resistance than the original so it is a mystery to me.
It's hard for me to believe that a fraction, maybe .15 of a ohm in a woofer crossover can account for such an obvious change in tonal balance, not SPL, and I'm more inclined to believe that the difference in the inductance is more of a factor as to where the highs start to be rolled off in the woofer.
As for very tight tolerances, I'm not sure I see a need for that in passive xovers because they are more or less all over the place depending on drive and frequency aren't they?
