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.

… they call it A1428WVL.

I am not well familiar with RCA 1428, so it difficult to analyze what is being done in there. It looks like the driver is driven by 30V – a bit too low. Considering the later high voltage discovers I would rather to have 100-200V field coil. The site said that the driver uses “composite cone”. I have no idea what it is. Anyhow, it is second attempt to remake the RCA 1428 after the Cogent. Sure it needs to be heard to see what they are trying to do.

What is very interesting to me is who the customers of Wolf von Langa’s products are. I am sure that the production of those things is expensive but there is dozen or so derange people around the world who curiosity in those things. I am sure to wish Mr. von Langa a prospers business venture but I just do not see it.

Anyhow,  a new Kilimanjaro-Series driver is out. I have no point of reference how good or bad they are and I do not see people talk about Kilimanjaro. It is sad as it would be interesting to hear from Kilimanjaro users.
