Thiel Owners


Guys-

I just scored a sweet pair of CS 2.4SE loudspeakers. Anyone else currently or previously owned this model?
Owners of the CS 2.4 or CS 2.7 are free to chime in as well. Thiel are excellent w/ both tubed or solid-state gear!

Keep me posted & Happy Listening!

Talking about 3.6's tweeter, recently I had  a look to the ferro fluid status because it seems to my to hear a bit reduced   high frequencies level (xover checked, all ok) and found not  dried up and  with a  normal consistency, very fluid. What in your opinion can be the cause?  Perhaps the stiffening of the dome rubber suspension after many years? They were made in 1998, dont know how long they can last delivering nominal performance.
The idea now is to proceed to take some measurements by means REW software with the UMIK1 microphone aligneted to the tweeter centre and 1meter far, a sweep in the range  1-20 Khz should be ok for the scope, do you agree?
Any suggestion on this matter  is very appreciated

silvanik - surrounds are very critical on tweeters. I don't remember whether those are rubber or a synthetic elastomer, but stiffening could be an issue. Your REW measurements shouuld tell you quite a bit, especially via FFTransforms to give you time domain information. If you can get higher than 20K, do it, since that tweeter goes to 28K and then some and that ultrasonic range might yield hints.

That UltraTweeter was used in the 2.2, 3.6 and 5. Madisound has the companion fiber moving kit, which is said to drop in without XO changes. Birger Jorgensen of Vifa, who codesigned that with Jim, took great care for the fiber and metal domes to behave as similarly as possible. One of these days there will be a replacement, but that motor will house the fiber dome if you need one sooner.

Thank You for the update on Mr. Rob Gillum. I would like to read more about Walter Kling. Is he alive and involved in Audio? Retired?

I hope that you are well and ready for Thanksgiving next week.

 

Happy Listening!

Thank You for being a valued member on the Panel. And addressing silvanik's 3.6 tweeter (driver) query.

 

Happy Listening!

Tom, thanks again for your valuable hints. I can extend the sweep up to 24K that's the limit in REW signals generator, I will do it as for your suggestion. I'll take the measurements separately L and R channel in order to compare the result, maybe the issue I think to have is only in my head....hopefully!
