| Thiel Owners As a quirk of history, the lower midrange boost referenced by unsound caused a bit of weirdness that lasted the life of the company. In order for the woofer/midrange to retain their coherence both drivers had to be fed the same equalized/boosted s... | |
| Thiel Owners Woody - the problem is that first order rolloffs engage the driver for 7+ octaves and Jim's designs control any anomalies via circuitry within that broad range. So, you can find many similar drivers, but re-engineered crossover circuits are requir... | |
| Thiel Owners JA - the upper crosspoint is the same 3kHz with very similar tweeter low rolloffs. The principal problem comes from the lower crosspoints: CS2.2 @ 800Hz, and the CS3.5 a full octive lower at 400Hz. The driver is asked to move a lot more air with l... | |
| Thiel Owners And regarding your replacement midrange drivers. Rob's replacement is a CS2.2 mid replacement and it will work. And none have failed in the field. However, be aware that its power handling spec is far less than the 3.5 mid. High power levels will ... | |
| Thiel Owners Woody - something that hasn't been mentioned is that Thiel, especially pre-coax models) require a listening ear height of 3' in order for time alignment. That's a baked in constraint. You can tilt the speakers to compensate for other ear heights, ... | |
| Thiel Owners Jazzman7 - sounds good to me. Shipping is problematic. I got a pair of CS3s shipped from Minneapolis to New Hampshire. Crating and freight cost around $700 combined, without insurance which would have added another $200. Let's envision a gypsy car... | |
| Thiel Owners I'll make some general comments from my study over these past few years. I wasn't at Thiel during the transition to China, but have learned some from first hand operatives. Here on this form there was surprise and disappointment that their Thiels ... | |
| Thiel Owners marqmike - thanks for the photo. I'll chip in later. | |
| Thiel Owners Yes - all Lexington boards are masonite, including all the CS2.7s. I speculate that the masonite board contributes to the reported sonic advantages of the 2.7. There is a bit of mystery regarding how the 2.7 can sound so good with that huge 400uF ... | |
| Thiel Owners Beetle - one of these days I'll open up a CYC 1uF bypass on your old board to see if I can tell what it's actually made of. | |
| Thiel Owners Perhaps someone on this forum knows the subtleties of polyester capacitor markings. MPT and MKT show up on lists as metalized polyester. I don't know anymore about it. | |
| Thiel Owners Agreed - except Thiel's custom 1uF bypasses were beyond polypropylene. They were tin foil x styrene film, which is close to teflon in performance. All the CYC clones were a level or two down from classic Thiel standards. | |
| Thiel Owners JA - I'll post a report after my visit there late August. | |
| Thiel Owners markmike - please post the pix and state your model and serial numbers. I might provide some clues. | |
| Thiel Owners JA - it seems that the SCD-1 is old business and I allowed him to back-burner it since I'm not in urgent need. He is also going to look at possible upgrades for my classic Classé DR6 and DR9s. I hope to pick up the Sony later this summer, if he ca... |
