Class "A" sound, as related to Stereophile.

Dave, I told the engineer I liked Thiel speakers; as I stated he was eccentric, after I picked out the drivers, he designed the crossover. As an example of his eccentricity; I told him I was going to change the value of a capacitor, and he told me he would crack my knuckles if I did; I left the capacitor alone. If you know the design of a Thiel speaker crossover, you're quite a technician. I'm sure you could build your own speaker, just make sure you got a good cabinet maker lined up before you start. Enjoy the music. |
Dave, are there any capacitors that can replace "Black Gates"? Time is what has to be in the evaluation for the answer to that question. I replaced all my electrolytics with Black Gates a long time ago, and all those old components function like new. I know Nichicon Gold might be comparable to Black Gates, the only question is time. Since they're all I know, I'll have to settle for them; also they're much cheaper. Enjoy the music. |
Hi orpheus10, From Stereophile June 1990 review: "The CS5 crossover is itself also heroic. Constructed on a single hard-wired board, it incorporates 87 elements realized with 114 components. Only—only—55 elements are directly related to the first-order high- and low-pass filter functions, the rest being used to fine-tune the system's time response. The two midrange units, for example, are electrically "moved backward," by the equivalents of ¾" and 3/8" respectively, to bring their acoustic centers into the correct alignment. All coils apart from one are air-cored, and the capacitors are polypropylene and pure polystyrene types, the latter custom-made with tinfoil plates and copper lead-out wires. The internal wiring is a polypropylene-insulated solid-core type." I have seen a picture somewhere of Jim Thiel holding this crossover. The visual impact of this crossover is breathtaking. Will keep looking. I don't think that I (or likely anyone else alive) can design something like this. Best to you O, Dave |
Dave, my crossovers have one for each driver, and I used Jentzen Silver Z- cap, except for the woofer where I use Solen Caps; all of that to get a speaker that does not exist. I've seen the Thiel crossover, it's a monster. Since I specified the big Heil Air motion transformer, he had to design according to that; they gave him a lot of latitude in regard to tweeter crossover frequency, and Thiel speakers were the closest to anything I liked in regard to sound. Now I've got speakers that have no sound, but the sound stage is similar to Theil, meaning the speakers I heard disappeared; state of the art ARC was used for the electronics, so that certainly helped. Of course I would never attempt to design a crossover; you got to know when to hold, and when to fold. Enjoy the music. |
