| Thiel Owners jafant - Yes The CS2 is the Dynaudio D28AF or later D28/2 which are Ferro-Fluid units. The CS2.4 coax (I've been told, but not certain) is also F-F Note there are many different formulae of F-F and only the correct one will keep the original pa... | |
| Thiel Owners Arvin - congratulations. The KEF Blade 2 is a magnificent piece of design and engineering. It does a whole lot right and I hope you enjoy them thoroughly. Of course, it doesn't address time or phase, so I trust that you have figured that in your ... | |
| Thiel Owners Unsound - thanks for the spotlight. Indeed his hypothesis of wire corrosion seems plausible and worth trying. | |
| Thiel Owners unsound - thanks for that link; those guys are serious. But their approach is different than mine. My interest is in updating and augmenting the original design for better performance and future maintainability while honoring the extant supply re... | |
| Thiel Owners In response to pieper1973’s query about home-brew cables, I thought it might be fun to recount my escapades over the past couple years. As you know, I’ve been re-evaluating classic Thiel products for upgrade opportunities and have reported many he... | |
| 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... |
