Thiel CS 3.6 mid-range problem


I have a pair of Thiel 3.6's, with a Mark Levinson No. 336 amp plus Levinson pre-amp and cd processor. I also have Audience AU24 "e" cables and AR6T conditioner. My mid-ranges are blowing out frequently -- 3 times this year. This didn't happen until I got my Audience conditioner and cables. The volume dial of my pre-amp is actually set lower than where it was prior to installing the Audience equipment. I don't think this is a case of playing the system too loudly. Time to upgrade speakers? Anyone have a solution or an idea?

Al, thanks very much for your advice. No, I haven't but I will start now! Question: should I power off the amp and then wait at least a minute before powering off the upstream components? Glenn
Al,

Once again, I appreciate your interest and advice. You're obviously an expert. In this case, the black wire connecting to the mid-range is the problem. When I removed the mid-range, I observed that the "black connector" on the back of the driver had about 1/4 inch of copper wire still soldered to it. The black rubber-coated copper wire leading from the speaker cabinet to the mid-range was intact, but was detached from the 1/4 inch wire attached to the driver. Inotherwords, I wonder if too much power (or something else) could overheat a wire causing it to split in two. Sounds far-fetched, but I don't know what would make that happen. Thank you again for sharing your knowledge! Glenn
Thanks very much. No, I don't use them with a home theater system, but I do have an audio system with a Levinson amplifier that is 350 watts per channel, fairly powerful.

After further investigation, it turns out that the mid-range driver is actually just fine, but the tweeter is blown. That has only happened once before in the 10 or so years I have owned them. Problem is, Thiel has no tweeters on hand, so they are having a batch made. However, Thiel won't receive them until end of February, 2011. If you like your music like I do (I'm sure you do!), that's an eternity. But, I don't have an option except to wait.

BTW, I am considering purchasing a pair of 7.2's. If I do that, would you have any interest in purchasing my 3.6's? I am the original owner. They are birdseye maple. The cabinets and grille cloths have no scratches or imperfections, but the black bases (which cannot be seen except on extremely close observation) have some dings and imperfections. I live in Louisville, only an hour from Thiel headquarters in Lexington, and could have Thiel refurbish them to like-new condition and avoid shipping charges. Glenn
Masri, I would sell them for a figure generally suggested by the Audiogon bluebook and would add the cost of Thiel's refurbishing the bases (I don't think that will be much) if you want that done.

I would sell them thru Audiogon. I don't want to break any of the rules, especially since everyone on this web site has always been uniformly honest, and everyone seems to do their utmost to make sure that transactions are easy. However, I would be interested to know whether you might be interested, and if so, whether you would want the bases fixed. I could make a decision whether to purchase the 7.s's within about a week.
