| Thiel Owners Hi Guys, As Beetle mentioned, I have a system for identifying cabinet misbehavior that permits real-time experimentation and amelioration. I use Chladni Patterns in my acoustic guitar design, I love the method, and will summarize here as applied t... | |
| Thiel Owners Because Thiel speakers present a sub-4ohm across most of their spectrum, dropping to 3-ish over extended ranges, the behavior of the amp from 4 to 2 ohms tells more than 8 to 4 does. | |
| Thiel Owners Thieliste, I have used many previous Pass amps and think very highly of them. (I don't know the INT-250). Nelson is a superb designer with values commensurate with driving a Thiel. The simple fact that it is doubling down to 2 ohms speaks clearly ... | |
| Thiel Owners Prof, obviously you need a bigger room. Build to golden proportions at about 12'3 high x 20' x 32' with "vents" near the corners (windows or doors work) and you'll have a room like Thiel's listening / optimization room and you can keep your 3.7s a... | |
| Thiel Owners Prof, I love it. Which model number? I need some long runs for house sound with CS 2 2s. | |
| Thiel Owners Hi guys. I'm not up to speed with which amps do and don't, but I do have lots of general Thiel experience. I have noted that current delivery capability is very important, especially in large rooms or loud volumes. If an amp doesn't double its 8 o... | |
| Thiel Owners In the late 80s Toyota was building their Georgetown Camry plant and Thiel, IBM, Trane, Square D and Toyota were core members of the University of Kentucky's Advanced Engineering Initiative. What a trip. Also, the CS5 was a big deal in Japan. The ... | |
| Thiel Owners Most folks agree that DSP is the future. The DEQX site is very impressive as are their reviews. The cost do "do it" actively and especially digitally is a small fraction of analog costs. And precision can be had. I note that ATC gives no phase spe... | |
| Thiel Owners With very broadband response with steep slopes, a driver could operate in its sweet-flat-pistonic zone. I would need convincing that higher order slopes could be "corrected" to actually produce minimum phase additions through the crossover. I've s... | |
| Thiel Owners Unsound, you raise a strong, well grounded germ of an idea. But in my experience and knowledge, active crossovers are a fairly blunt instrument. Their downfall is that they generally assume a very simplistic model of the driver and therefore give... | |
| Thiel Owners Robin, the CS series have enough internal enclosure volume to tolerate the added bulk of the upgraded crossovers. We'll produce upgrades both inboard and outboard. | |
| Thiel Owners Prof, thanks for the reference to Phil Bamberg. He is part of the picture and solution of the puzzle. Your quandary of 2.7 vs 3.7 shines a light on some design particulars of interest. The 3.7 has no electrolytics in any signal path, whereas the 2... | |
| Thiel Owners Thank you all (I'm from Kentucky) for your participation here and via PMs. Here is a progress overview.Indeed a high priority is to avert losses from aging electrolytic caps. New work will have ALL film caps for indefinite product life. In broad o... | |
| Thiel Owners There are substantial differences applied to the coax by the two designers and/or assemblers. I have Jim's 3.7 schematic + layout, but only a designer layout for the 2.7. The 3.7 was all Thiel in-house and it seems the 2.7 was outsourced to ERSE-... | |
| Thiel Owners Hello everyone. Thanks, beetle for the update and I appreciate whatever feedback you guys can give. There are so many considerations and development requirements, and so little time. But I am making progress. Unsound, indeed our crossover cases wo... |
