beetlemania,
There are still questions about the Wax coils values, my LCR meter indicates that they are too high in value, they are sent to Jantzen and according to them they are within the specs, next week I get them back and can tell more.
For the time being they have not been in the woofer crossovers yet.
Regarding the Jantzen foil coils on the coax board (which were part of the last total upgrade), I can not say anything specifically about what only the foil coils do in the whole picture, but the entire upgrade gives a significant improvement in SQ!! the key points that I hear are even more air than before, now it is as if the space embraces you and takes you to the room where the music actually plays out, also the width of the spatial image is now more outside the speakers and also more forward , the naturalness is also very impressive !!
All in all, I was already very happy with the CS2.4 but after the upgrades I now have speakers that I never thought I could own :-)
