thoft,

Its not really the watts as it is the current to handle a load.

A Pass X260.8 is right at that 1000 watts into 2 ohm load. Switching it out to the X600.8 is a very noticable difference especially in the bottom end.

The best test is to see if you can get a loaner amp to try and compare it to the Classe’. If that does not show improvement then you know you need to look elsewhere in the chain. I'd hang onto the Classe' until you work out whats the solution.

Hello, I’m new to this forum but not to Thiel. My first set of CS 2.3 were purchased in 1999 which I still have. I recently got a second set of CS 2.3 - used - but the first version coax drivers are bad. I sent them to Coherent Source Service for rebuilding. Rob there quoted 3 days for the work but 2 weeks later they are still not done. When I asked for a realistic completion date, he did not reply.

By luck I found updated 2.3 coax drivers on eBay couple days ago and bought them. The install instructions posted in the listing do not cover how to update the crossovers. If anyone has the instructions for the crossover update, I would really appreciate a photo of it.

Welcome! Good to see you here. The Panel has a few fans and owners of the CS 2.3 loudspeaker. Stay tuned until one of our experts chimes in to address your query. Thank You for citing Rob at CSS. He is a 1-Man Operation and has a pretty quick turnaround overall.  I look forward in reading more about your Musical tastes and System. Keep me posted on the Repair process.

Happy Listening!

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.
