A while back I measured all the crossover components on my 2 pairs of 2.3TL's. One inductor in particular (the one labeled as 0.3mH on the schematic) measured about .18mH, or about 40% lower than the schematic value. This changes the response of all 3 tweeters.
Since I measured this .18mH value on all 4 speakers, and the 2 pairs are pretty far apart in serial number, that would seem to say it wasn't just a bad batch of inductors at one time.
Does anyone know if this change from .3mH to .18mH was an official change that just didn't get included in the schematic?
