Thiel Owners

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 :-)

what strikes me is that if you press the passive woofer the active woofer (of course) comes out but then almost immediately it will slowly return to its neutral position, so there is some air leakage, is that intentionally also the intention or do I have to look for the leak?

Holco - thank you for the report.
Regarding leakage - ideally you want none, but practically a small woofer enclosure leak doesn't do much. Are both channels the same? Of serious concern is if the woofer enclosure leaks into the midrange sub-enclosure. Push both the woofer and passive and see if the midrange moves. If so, troubleshoot.

Regarding foil coils. I await your comments on that change. News from the research front: foil alloy is considerably purer than wire alloy. As I've mentioned, Thiel used 6-9s ultra aerospace wire from 1978 onward. By 1995 that wire was no longer available and we used 4-9s specified as C10100plus. That seems to be the best wire currently in use, except for specialty boutique producers such as Cardas. I have learned that ERSE, Jantzen and other high-end suppliers now top out at 3-9s C11000 @99.9% with higher oxygen allowances. Jantzen specifically disclaims audible benefits beyond this C11000 grade, etc. etc.
My personal experience is to the contrary, having spent the summer of '78 comparing wire. Some auditory brains hear the difference. I am currently exploring a solution strategy.

Beetle - your FST coils and hookup wire meet the C11000 spec. But your FST coil winding was less than best. I await your experience with Cardas hookup wire.

Audio inductor foil meets better than C10100. It is as good as the original ITT 6-9s aerospace wire that I secured in 1978. So the generally accepted higher performance of foil coils might be attributable to some combination of  foil skin effect reduction, tighter wrap and purity of alloy.

Lotta mystery.

Great that there are subjective improvements noted with the upgrade. Can we agree on objective measurements that would capture such an audible improvements and continue the Thiel tradition of both objective and subjective substantiation of improvements?
