Thiel Owners

Finished the second loudspeaker and there seems nothing wrong, except my jaw is laying on the floor, what a great great great sound!!!

This still without the Jantzen wax coils.

I'm loving the enthusiasm I'm hearing from you both.
Beetle - indeed there are great expensive drivers and some including Vandy who took Jim's lead in using copper motor shunts. Jim invented the solution on first principles and only when applying for patents did he learn that the solutions were lying fallow in the public domain for a long time. Faraday Rings.
Holco - your coil wire is ERSE or Jantzen 4-9s round and bonded, so your foil coils will be different in geometry and bonding only. Your comparison of the round vs foil is of great interest to me.  

Tomthiel,

A transcription about the Jantzen wax coil’s from a Dutch guy I really trust, Tony Gee

To get straight to the door: I absolutely love it! 8) With the 1.5mH Wax Coil I did a 1 to 1 comparison with a normal air coil with 2mm wire (Rdc = 0.22ohm) and a CFC-12 copper foil coil (Rdc = 0.21ohm), both from Mundorf. Furthermore, I have used both the 1.5mH Wax Coil and the 0.47mH Wax Coil in a number of different filter configurations.

What is immediately noticeable compared to an ordinary air coil is the large increase in spatiality and placement of the individual instruments in an orchestra. This phenomenon is something that ordinary copper foil coils also have, so not surprising that the Wax Coils in that respect are better than standard air coils. But what they offer even more than a normal copper-foil coil (and I’ve fallen for that), is the whole natural and expressive harmonic structure. Strings sound delicious to wood, intestine, horsehair and resin. Sopranos have a natural heat in their voice, etc.

These positive qualities are best reflected in classical music, singing and acoustic instruments, with "produced" popular music in particular the extra spatiality.

Today marks the 3rd Anniversary of this thread. In 2016, I started with post #1 from a fan's standpoint for Thiel Audio. I came to admire the design, form and function of these wonderful loudspeakers. The hope was to gather interest from like-minded Audiophiles. Well, it tuned out that there are more than a few of Us. Some have left to pursue other speaker brands while most of you guys are still here. This is a testament to Mr. Jim Thiel's hard work and passion for seeking nothing but the best in  presentation, sound reproduction. Several of you guys are experts on this brand exclusively.
Over time, I adapted this thread to catch all Music lovers from entry level, hobbyist, moderate, novice and expert. Recently, we have managed to attract electronic DIY and speaker building contributors. Moreover, there are occupational trades and professionals here. All of these attributes created an esteemed Panel. Talk of Thiel Audio crosses over into other audio forums as well. Those guys contact me away from Audiogon. I ask each and every one to join us here to continually improve this experience.I could not have predicted that two distinguished Gentlemen would notice this thread. Mr. Tom Thiel and Mr. Rob Gillum. Even though Rob is not involved directly, he has perused this thread. Tom has become a very active, all hands-on deck,  historical Asset. Thank You All - for your contributions, insight, impressions and listening experiences. The Audio Journey and Process starts here.

Happy Listening!

And hats off to you, jafant, for getting the snowball started down the mountainside!  Happy anniversary!
