Thiel Owners

ok, as promised here is my lengthy write-up of my summer project modifying my Thiel CS3.5https://drive.google.com/file/d/1A1Hs9g2tr27cGUfzSX8IcUy3dC-TpVrk/view?usp=sharing

jimi handtrix - likelihood is very high that your tweeter is "blown". You can test it by taking it out and applying 6 volts DC via a battery. When you touch Tweeter Plus (red) to Battery Plus you should hear a small click and feel the dome against your finger move outward. If nothing happens, the tweeter has failed and we here can help you get a new one.
The woofer should move a lot at high frequencies because it rolls off at only 6dB / octave above around 3K± (guessing).

Welcome! Good to see yo here. Standby until one of our vintage experts from the Panel addresses your query.  I look forward in reading more about your musical tastes.

Happy Listening!

Good to see you here: corrected.

Agreed- the CS 2.4SE does not benefit from toe-in. The upgraded cross-over (XO) and Outrigger decoupling makes a refined, sublime, difference.

Happy Listening!
