Which RCA driver you use? RCA had a few drivers the pre and after war. I am familiar with a few after war drivers that I tried in my 330Hz horn and I was not impressed. Reportedly the pre-war MI-1428B shall be the one to play with; I did not have thi...

Here are some of my observations regarding the Wolf von Langa RCA 1428 replica. I long time wondered where mr. von Langa gets his phase correction elements and the diaphragm for his RCA 1428 replica. It's obvious that a niche-manufacturer such as W. ...

No, the 1443 is also a field coil, just a different voltage.Re: the configuration - indeed; I am hoping to get 300Hz with the RCA, then the S2 from between 1k-1500 and up, + tweeter. Below the RCA willbe a compromise to begin with, but hope...

This record survived my college days, but I thought I'd lost it along the way. How nice to find it and hear it again, after so many years.The tracks from this LP were dubbed from recordings made in 1926, 7 & 8, presumably originally di...

I spent some of yesterday listening to the 8th and 9th from this set.
Recorded in mono by RCA in the early 50's I really like these performances. As a bonus the recording quality is good too. Does anyone else know them?...

I would be very interested to know what Richter said about this in his diary. Apparently, this was Richter's 1st American recording, and all did not go well, at all. For instance, from a long list of unlikely "catastrophies", Leinsdo...

If the RCA 1443 the same as 1428B but without the field coil then it might be even more interesting than 1428B. As I understand that those prewar driver had phenolic diaphragms that generally shall have tendency to be a bit soft with low order filter...

Interesting, at this stage it's early in your testing so I am mostly interested in how they are terminated. Can you provide a picture of how the fluid tubes are sealed and the cable terminated to RCA?

In fact I posted a question to Wolf and he replied that he can produce the coil of any voltage the customer would like to have. That is good. The below is data by Wolf von Langa:

In the thread “Vitavox S2 with Electromagnets.” there was plenty of discussion about RCA 1428 driver. Here is more to it: the Great Vintage Loudspeakers made a new production of the RCA 1428 driver.

Without wishing to open a can of worms....Mine are the 1443 - same as the 1428B save for the field coil voltage. I've finally got round to ins talling some of Cogent's replacement diaphragms to restore them properly. I can't say enough good thing...

Yes, I understand Bud that anything might be done but I do not want any DIY solution. To deal with all of the shielding, with grounds… I do not want to be involved into all of it. Also, the transformer shall sit at the RCA exit jacks of phono cable. ...
