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.
