I spoke on the phone with the manufacturer and he assures me the new production is exactly similar to the old drivers, the machines and people making them are the same.About the diaphragms, the last batches of the old drivers already had the diaphrag...

Here's what's behind my comment regarding the irrelevance of color: I strongly suspect that the new production diaphragms will come with transparent Mylar suspension. In that case, I would hope they turn out to have the mechanical properties of the w...

[quote user="Bud"] I have a really barbaric suggestion... of course. I can set you up with 8 lLinaeum, soft, live horn, dipole tweeters. Stacking 4 per side should see you at 103 dB sensitivity and 8 ohms of impedence. You can stack them without inte...

Zanon, I do understand the sarcasm you would like to express. From one side I insist the people are clueless based upon that fact that they have not aliened diaphragms and from another side I pitch that the perfect alignment might be accomplished onl...

[quote user="Jorge"]One more thing about the JBL 375, I did play around with them enough, I aligned the diaphragms several times untill they sounded their best and were very listenable, This was some time ago now, I didnt turn my horns then, so I tr...

Ah, such a beautiful beautiful beautiful beautiful discovery!
After all, after the years of dealing and fighting with it I come up with the observation that the Vitavox S2 driver could and actually should be used “as is”. The harshness that I was re...

I did not see in your post any “sad truth about BMS”I would stick in the JBL 2440. It is relatively inexpensive. Has practically the same performance as the hipped JBL 375 and all together a good performer. It’s diaphragms are wildly available and it...

[quote user="Romy the Cat"] For above 550hz you might use the same LL1627A if you wish, for MF the 200-250mA gap will be fine. Yes it would be reasonable to desire less inductance in the transformer, mean less turns but honestly I personally did not ...

I just posted yeastoday the post above and have got already a few emails asking about the “new” ways that I am planning to use S2. OK, let me to explain what is going on.
The default Vitavox S2 driver comes with thier default aluminum diaphragm with...

Hi, Tim. This is difficult question, and it is difficult in it’s abstractivnes. I really do not understand, or understand but refuse to acknowledge the validity of the word “respectable”. How valid for YOU would be a “reputation” of this driver if it...

electronluv do's not have the ability to make beryllium diaphragms or the legal stuff to even buy raw beryllium i bet with a little surfing you may find the companys diaphragms i use .Yes 3.25" is to help get beter HF extension but to also get a very...

I went to eBay and searched for his diaphragms. If you look for the rest of the items he sells then you see that he sell vintage labels of Altec, Western Eclectic, JBL, Rogers, Studer… Well, in my books the people who sell it and those who buy it hav...

Op, I clearly have no idea as I never have seen/heard about the 2440 with phenolic diaphragm. Who know perhaps they did it. The phenolic diaphragms were the invention in late 60-70s and a remedy against the nastiness of the first SS amplificatio...

Yes, Rulit does try to push envelop of something. He does exiting projects but I do not know how all of it manifests itself in actual results. I said that he pushes the “envelop of something” as I do not know what this “something” is. I never h...

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...

well i never thought i would be opening such a pandora's box with this combination.firstly,the drivers have the plastic surrounds(whew,lucky!i know the diaphragms are potentially harder to source than the drivers)what indicators or criteria would mak...

Ming,
thank you very much for resonance information, it explains a lot about the SG145LD4’s suspension. Still, my primary interest was not how folks out there build 20Hz of 24Hz horns but about ability to use the SG145LD4 properly for smaller horns...

Whoever followed my bothersome experiments in search for a better diaphragm for Vitavox S2 driver knows that I lately spent quite a lot time trying to make the original metal suspension diaphragm to work. There are a LOT of advantages in those diaphr...

It does sound like a shoping list, not my intention, I was mainly trying to address some points 3 mainly:1- You have stated before that the 2440 or 375 is a good sarting reference, so I wanted to keep that comparison point. thats why I went back t...

Paul,The two channel system is separate from the HT system - the gigantic plywood folded horn subwoofers support the screen but that's the only connection to the HT audio system.The HT system is three Orb Audio 8" powered subwoofers, 3 x Gallo Ref. S...

For all I know, "alignment" is digital. And IMO, so far, "super hard" tweeter diaphragms have not lived up to their "reasoning". In fact, I would have to say the same for any direct radiators with "hard" diaphragms that I have heard to date. Agai...

[quote user="vinylithicum"] 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 ...

Hm, SGSG-37FRP, Driver frequency band: 400Hz - 10kHz, 18,500 gauss SG-370, Driver frequency band: 400Hz - 18kHz, 23,000 gauss SG-370DX, Driver frequency band: 400Hz - 20kHz, 24,000 gauss Inversing, they build up magnetic density and extend HF. I...

This is something I have been at for the last few years, I have tried a few drivers, at the moment some of my favorite are the vintage RCA MI 1443, yes filed coil and some funny cone diaphragm, they are used from 500 hz to 5 khz with a Fostex T...
