I don't know how they compare to some of the latest and greatest recording techniques, but I have always been impressed by recordings on the now sadly defunct Dorian label. I happened to be going to...

I do have a pair of 4648As already, but I'll shoot you a PM. Thanks!

Hi Rudy, sorry missed your post somehow. These are the cards I'm using. Are the ones that you have different?

Just checking in, no further progress on this front but still planning to run some more cases and do measurements. Been distracted with trying to get one of my turntables up and running (ELAC 50H /...

I haven't used them yet, but have looked at this board prototyping source several times.

It may depend on the specific mount and horn I suppose. I'm using the 2506B mount on the 4648A w/2365A horn, which puts the CD (very) roughly 19" behind the woofer voice coils. I'll need to do real...

Yeah, I'm sure a digital crossover would be easier. But what can I say, I'm an analog/RF guy. DSPs seem like cheating somehow ;) At this point the project is as much for curiosity sake as...

Interesting, thanks. Look forward to looking over the board files.

I'm slowly working up to trying to simulate my whole system chain (at least from the pre/pro output on), which is sort of the...

With the help of the schematic above I was able to simulate the 500CC card as follows:

Thanks dn92, there is an amazing amount of info collected there. Even with the google translation its a great resource!

PS if you are still willing to share your board layout files I would love...

Hello all,

I know there has been some work done in the past on figuring out the schematics and component values for these cards. I thought I'd see if anyone had any pointers / advice on setting...

So here are some preliminary sims to explore the UHF crossover question. For simplification I'm not trying to simulate the existing active crossover, just assuming the bi-amped HF and LF are well...

Thanks hack, the center channel is definitely the weak link in the current system. Its not terrible, but was just made up of the left overs in its current incarnation. I guess the ideal thing would...

Greetings!

After lurking for quite a while I wanted to start a thread here to introduce myself and see if folks have any thoughts / feedback on my project. I'm afraid I've gotten bit by the audio...

I recently acquired one of these oddball 4660s with the 2225J woofer and 2346 horn with 2425J CD.
