Thiel cs3.6 keep blow up mid/tweter driv

drtmth58 is quite correct in his admirable post. amp clipping is, indeed, the most common cause of speaker failure. it takes high ouput and high current to drive difficult loads to high spl's. my advice: change your amp before replacing another driver. -kelly

I have a Thiel 3.6 as well being driven by a Krell FPB200 and so far I only have one tweeter go bad on me in almost 2 1/2 years that I have it.I called Thiel and they shipped me a new one right away after I called and told them about it.Give them a call and I'm sure they will give a better answer than any of us here.Thiel is one of the best when it comes to customer service.
On a side note I also read on another forum about somebody who had the 3.6s and had 3 or 4 sets of mids and tweeters go bad in a couple of years time. If I remember it correctly he sent them back to Thiel and they found that their's something wrong with the speakers crossover. Thiel fixed the problem and he never had a driver go bad on him since.

thiels are wery demanding of quality amplification & lotsa current - normally, i'd take the adwice of drtmth58 & cornfedboy. but, in this case, yer amp is up to the task. so, i'd suspect ewe have a problem similar to that referred-to by rmml. call thiel, & they should take care of it for ewe.

good luck, doug s.

I had the same problem with my 3.6's. In my system it turned out to be a micro-short in the interconnect between the pre and amp. Thiel told me the 3.6 drivers will pop everytime if there is a problem in the upstream electronics.
