Thiel Owners

vm1 - Rob is the expert, but he sometimes goes dark due to personal circumstances. So, let's go. The CS2.3 came out in 1998 and the coax was revised early 2001. The revision was adding a bucking magnet to the coax to eliminate video interference. That also quiets stray EMF field interactions with the crossover network. All good. Possibility of other changes unknown to me - I wasn't there.

I have a factory XO drawing dated as 11-17-08 and 2-2-01 which times up nicely. Rob has said the coax change was made at #4567 which is pretty late in the product life. I can share this schematic with you, and would appreciate a photo of your XO and serial number. If interested, send me a PM.

Thank you for your expert advice as always. 
I hope that you are well and recovering from your recent journey.

Happy Listening!

Thank you jafant and tomthiel. THE Tom Thiel? Wow! Excuse me for being so green. Here is a little more detail on how I ended up here:

My first set of CS 2.3 is 23 years old. I thought about buying newer and better speakers. I went to Rockport dealers to listen to their entry and high end models. They were excellent speakers, but surprisingly they did not impress me as being far better than CS 2.3 despite their astronomical prices. I came away from those auditions far more impressed with the quality of Thiel still comparing so well against new and ultra expensive speakers. That’s how I ended up getting the second set of CS 2.3 for a secondary residence, which apparently was over driven and had fried drivers. Turns out the eBay seller of the drivers has the instructions for updating the crossovers.

Thank you tomthiel for making such a wonderful product that truly stands the test of time. By the way, I have the chance to get a pair of CS 6. Are they significantly better than CS 2.3?

vm1 - Thank you for your kind words. We did indeed hope to create speakers to bring musical enjoyment for a long, long time.

Regarding the CS6, there is lots of good information in this thread, some quite recent. In broad terms, Thiel was a cost-plus operation, what you paid reflected what went into the product with old-fashioned (tight) margins. If the CS6 sold for double the CS2.3, it had twice the manufacturing costs (simplified model.) The model includes having twice the budget for amplification to support the larger speakers. And a larger room . . .  Supporting a CS6 purchase is much costlier than the 2.3.

Tom,

"Supporting a CS6 purchase is much costlier than the 2.3."

I can bare witness to the truth in that statement.
