Blown CS7.2 Tweeter/midrange

My tweeter has been repaired free of charge. Gary Dayton from Thiel told me that the tweeter's moving part failed. My amps didn't burn the tweeter. That is why they didn't charge me for the repair. Now I am in business. Thiel's customer support is excellent and Gary was extremely professional and helpful.

Ckoffend,
I agree with you. It could be the amps. However, the amps I am using is a pair of Lamm 2.1 mono blocks that I trust. They are rated 200 watts at either 4 or 8 ohms. It has a switch at the back to select the ohm setting. It is class A up to about 36 watts, then AB above 36 watts. I would think the amps should be adequate. I have this amps and speaker combo for a year without any problem until last Sunday when the tweeter blew. I have yet to hear from Thiel about the cause of the tweeter failure.

In fact, I played louder than 90 db before on some occasions with ultra dynamic classical music. I was just playing the first cut of side one of Art Pepper "Meet the Rhythm Section" 33 rpm by Analog Production when the tweeter failed.

That said, 300 watts could be a better match with more power as reserve.

Tom_hankins,

What big Krells are you talking about? I used to own JC-1 that sounded fine, but not great. I also had a pair of BEL 1001 mono blocks that sounded great, but the Lamm 2.1 is the best. Well, now I am re-thinking about this and may need to change amps. I will report what Thiel is going to say.

Tom_hankins,
I am not a fan of Krell at all. I guess I may try a big Krell some day when an opportunity comes up. Not to offend anyone, my past experience with Krell (older models) was that they sounded whitish or bleached. Don't know about the newer Krell sound though. The Lamm has a very nice balanced and rich sound.

Folks,
I have been playing at around 90 db for the past two years without any problem. I hope it was the tweeter's fault. I will report as soon as I hear from Thiel, possibly some time next week since this is a long weekend. Stay tuned.

I also sent a "thank you" email to Kathy Gornik, President of Thiel about the excellent customer support I received and asked her when Jim Thiel would come out with a new flagship speaker system to replace the legendary CS7.2. She said Jim was not working on the 7.2 replacement at this moment since he was busy with other projects. I really wish Jim created a new flagship at a killer price.
