Thiel Owners

Does anyone have the specs on the tweeter for the 3.6(D26AG-36)?  If you listen off to the side and rather close to the tweeter you can hear crackling on music with strong lower treble upper mid energy - like timpani for classical music.  If you listen out front you can't hear it at all at any volume.  I'm not sure how long this has been there either. 

What are the chances that something has gone bad on the crossover?

Will be calling Rob about this on Monday.  Want to see what else is out there should I need new tweeters.

@therealpupalei - what do you think of the PS compared to your previous Krell?

I'm using a Krell TAS to power a pair of 3.6's.  Love it!

Another thought - does anyone have 3.6's that could run a test for me?  I can send you a song that produces the crackling.  I'm thinking this may have always been there however you don't hear it unless you are really close and off to the side of the tweeter.

I've already tried this on the 2.7's and did not hear the crackling regardless of where I stood or how close I was to the tweeter.

Sounds like a fried tweeter to me. I think what causes it is when the leads break, the strands tend to be touching at low volume but at high excursions they lose contact and then regain it, causing a crackling sound. I recently had this problem with a Thiel Viewpoint I got off of ebay. It was damaged in shipping and I glued the woofer together and got it working. The tweeter was crackling though, I took it apart and saw that strands of the wire leading to the voice coil were broken. I ordered a new tweeter and it had the same problem almost immediately. I took it apart again and the leads were broken just like the other one. I measured the crossover output for the tweeter at 60hz and it was the same as the output for the woofer. The crossover was damaged in such a way that it was frying tweeters.

@ctsooner That is what my hunt has been for. Any speaker can produce sound. A carefully matched system can reproduce music and that is what I’m after as well. Currently my most involving setup is this:

Intel NUC running wtfplay (Synergistic Active USB) or Cal Audio Labs CL-10 (Synergistic X coaxial) --> MSB Analog DAC --> AudioQuest G Snake --> Krell FBI Integrated --> AQ 4 (I think) speaker cables --> Thiel CD2.7

Big wide deep dynamic with what I hear as accurate timbre of instruments.

When I need bass that the 2.7 cannot reproduce I hookup a Definitive SuperCube II to the preamp outs on the Krell.
