| Thiel Owners biannuzzi22 - PM sent to you. | |
| Thiel Owners biannuzzi - here's some background that might be useful. The CS3 and its replacement the CS3.5 share the same enclosure volume and woofer, except for addition of an applied damping compound to the 3.5 woofer, which you can get from Rob. In my opi... | |
| Thiel Owners improvedsound- you’re in the deep end, so take care. My knowledge is anecdotal and experiential. I have experimented with foil inductors enough to learn that I’m over my head. Indeed a foil inductor is a more perfect inductor than any wire induct... | |
| Thiel Owners jazzman - you should be fine. It seems most of the "difficult period" might have been 2003-2004. Thiel probably found better sources, plus China definitely improved its development and manufacturing chops year on year. The the tell-tale test is ... | |
| Thiel Owners The pictured XO looks just like mine. If 2951-2 look like that, they're from the same era. Those black caps are polyester-mylar (one down from polypropylene), the coils are well-made from CDA-102 wire, which is high-end regulation wire, one step d... | |
| Thiel Owners About the CS2.4 serial numbers . . . I’ve been piecing together the history puzzle. What seems clear is that the transition to Asian inputs such as CS2.4 crossover manufacture was far from smooth or steady. Even though Rob says Lex 2.4 XO manufact... | |
| Thiel Owners @sdecker - wow also. I didn't know about the wayback machine! pieper1973 Nice work. Your CS2.4 serial numbers @253-4 are right near the transition from Lexington-made original boards with American / European parts, point to point on masonite boar... | |
| Thiel Owners unsound - thank you as always for chiming in. Indeed a replacement driver is really the beginning of a redesign project and not the end. To elaborate: as you say, Jim considered all aspects as a system. Each driver has its Thiele/Small parameters ... | |
| Thiel Owners Tom D - the whole matter of bass is deep and sticky. I have spent considerable attention on the problem, and am still in the dark. But here are some thoughts. Put your boots on because we're going in over our heads. At Thiel we did tons of (non-m... | |
| Thiel Owners Jim - Memory develops holes at 40 years out. This morning I pulled a tweeter on a CS3 I have in storage. Yep. The tweeter cavity has a 1/4" thick back with a lag bolt to the cabinet back. (No dodging - I did it!) That isolated the tweeter, plus wa... | |
| Thiel Owners Jim - let's revisit your actual questions: Tweeter cavity - I don't remember that tweeter mounting having a back in the cavity. It is possible that the early iterations, like yours, had it and it didn't stick or that you have an aftermarket tweak... | |
| Thiel Owners Tom - thanks for your comments. The entire arena fascinates me on multiple fronts. First is that "the problem" had been solved to our (Thiel's) satisfaction by 1983 with the CS3 contoured baffles that practically eliminated diffraction and baffle ... | |
| Thiel Owners JCHussey- I would like to address your CS3s. This model is the de-facto watershed that put Thiel on a solid road to success. The CS3.5 gets more respect, but it is essentially the same speaker with a better midrange driver. Taken together, the CS... | |
| Thiel Owners JAFant - what I meant to say is that the stock CS2.4 has its crossovers positioned quite optimally - more so than most Thiel models. Here's some background. Although we were aware of sonic degradation when the free-form / bird's nest development ... | |
| Thiel Owners I get it. Too bad Thiel XOs are so complex. But that's what it takes to control a driver over 7 octaves without having detrimental effects on frequency, phase and time response. One of these days I'll find the opportunity to put a Path in the cri... |
