Thiel Owners

silva - I believe that you made improvements. I am merely addressing the physics of the cause. I suggest googling "speaker enclosure resonances" or somesuch and see what you can learn.

It's quite complex - resonances couple when harmonically linked (like octaves, etc.) But a very big deal is that the lower a resonance occurs the greater the available energy to stimulate it and the longer it will last in time (all else equal) . . . both being detrimental. The dance is to shorten their duration and push them higher where there is less available energy to stimulate.

Lead is mechanically very absorptive and self-dampening. It is the right idea for the right result, but the lowered resonance frequency is an undesired by-product rather than the cause of improvement. 

The Jantzen caps are now burnt in for a week, it's incredible how much potential the coax driver has with better capacitors!! Loved my CS 2.4, love them now even more :-)

Has anyone tried Paul Speltz's Zero Autoformers to change effective impedance, allowing for the use of lower powered tube amps to pair well (or at least better) with their hard-to-drive Thiel's?

holco - you are welcome to share which capacitors you changed and why and your specific listening experience.

Hi Tom,

I changed the 13uf and 1uf for a Jantzen 10uf Superior Z-Cap + Jantzen 3.9uf Alumen Z-Cap and I changed the 27uf and the 1uf for a Jantzen 18uf Superior Z-Cap + Jantzen 10uf Alumen Z-Cap.

The why is because I wanted to upgrade to the SE version capacitors but the Clarity SA caps are a lower grade than the now used Jantzen caps.

Don't know what you specific mean with listening experience, but I am a audio lover for many years and have build up a nice audio setup.
