Thiel cs3.6 keep blow up mid/tweter driv

Man, that stinks! I have a 3.6 and "knock on wood" haven't had any problems and I crank it pretty good on occassion with a classe ca200. Unless you really crank it until you hear some breakup I don't see how it blows, it sounds like some sort of short somewhere. what does Thiel say about it? lots of components in that crossover that's where I'd start. good luck.

I have a pair of 3.6's and have never had a problem and I listen quite frequently to Tchaikovsky's 1812 Overture with the digital cannons at fairly high levels. I would call or write Thiel. Good Luck, Chuck

I strongly suspect the problem may be with the amplifier and not with the speaker. The Thiel 3.6s are terrific speakers, but because of their occasionally very low impedance are quite difficult to drive. The manufacturer recommends Classe, among other designs that have sufficient current to handle 2 to 3 ohm loads. I would imagine a Bryston 7B-ST would also be satisfactory, as might a Sunfire. But if you attempt to play the speakers at loud levels with a less than satisfactory amplifier for this specific application, the amplifier is apt to clip (which is generally the most prominent cause of tweeter and/or midrange failure) or perhaps even go into oscillation, which would also burn out higher frequency drivers.

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
