[quote user="guy sergeant"] I think it would be quite difficult for anyone to set up any sort of production of drive units and not become an 'industry' participant. It's quite remarkable that you manage to use a turntable, arms, cartridges, CD Player...

hi. That’s a nice topic. I studied the VO like a maniac. For me there are 3 topics. First was obvious, easy, the horns. The bass horn for the ak151 is housing a rear chamber slightly open, giving the injector channel - that creates a lot charme, flav...

No time, can only post in snippets...The second hand S2 and 15" Vitavox that I have were all compromised by age and use and have been thoroughly cleaned and remagnetised and where appropriate Sent to the UK to be reconditioned by Vitavox. ...

What are we to make of this: http://www.vitavox-sound.com/ ? Or am I a long way behind the news....

Romy I read your post listing some aspects of the Vitavox drivers Mike might take a look at and I know you give acoustic reproduction a lot of thought, have you envisaged the 'perfect ' driver, has the Vitavox enough 'accidentally good' qualitie...

[quote user="Romy the Cat"] The S2 has own very idiosyncratic upper range with own helpful resonances injected into sound. I feel that that original metal suspension diaphragm does it bolder and more aggressively then the plastic suspension dia...

I think guessing what the hell they did with tweeters would make since if whatever they did sound right. Since Living Voice’s is not the company that has a lot of exposure in US I do not think I will ever hear those speakers. Even if they have US rep...

I kind of fed up to receive those emails (I ordinary do not reply them) with questions and therefore I would a would make one atypical public statement and it will be it. I say “atypical” as I truly do not care about your purchasing habits, still sin...

Hi how did your vitavox speaker project go?Im looking for a 1956/57 single original cone 15/40 to complete my vitavox project. Anyone got one?...

[quote user="guy sergeant"]He is in a difficult position. Does he make a the driver using the tooling/knowledge/supplier information he has acquired from Vitavox(and change nothing)? This would be actually be a Vitavox S2 (not a repro) or does he try...

Last week I have written an article: “Upperbass preoccupation and Vitavox S2 driver” where I ran over some my thoughts how the specific sonic virtues of Vitavox S2 driver allow to get an “interesting” upper bass from an upper bass channel, even thoug...

He might be a fraud or it might be that he did found some stock of “different” Vitavox or Mike’s diaphragm. I do not think that there were any standards and the make different production runs, and some of them might be better or worse than other....

A few months back a guy from Europe showed up at this site proposing to sell a set Vitavox K15/40 and Vitavox S2 drivers. I did not need them, I have my own stash, not one looks like needed us as well. In a couple months he reinstated that the dr...

[quote user="jessie.dazzle"] Color or opacity of the material in itself means nothing; it could very well be white, pink or have leopard spots (I'm betting you'd like that!), all independent of its physical characteristics. [/quote] Of cause the colo...

[quote user="Romy the Cat"]I am glad that Fane “now found … that they have sufficient old stock of the 8 ohms or 16 ohms voice coils to”. Such a phenomenal discovery of the British archeologists. Can you ship them here in US, they can help us to fin...

John, I see where you go with it. I afraid that I will not be making my drivers – I have no idea how to make them in order them to sound the way I need. I have no problem to design and to make 4" exit compression driver or to undertake a project to r...

[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 ...

[quote user="jessie.dazzle"] Once I am done with more of this project, I will make a 330Hz Tractrix to try in place of the upper mid 400Hz. [/quote]
Hm, I wonder what would be the purpose to make 330Hz horn for you if you have 400Hz and a dedicated ...

[quote user="guy sergeant"]I had dinner with Mike Harvey from Octave this weekend. Mike acquired the intellectual rights, tooling, drawings and jigs needed to manufacture the S2's. I believe that newly manufactured S2's will be available very soon. M...

Actually is has less to do with familiarity with a piece but I fe...

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...

[quote user="jweiss"] When we spoke at CES, you mentioned that your experience with field coil drivers only extended to cone types. So I assume that you have never heard any field coil compression drivers. That would include the WE 555, 594, RCA 1428...

user="jeff1225"]Romy,When you say that the Vitavox 15" was the
best midbass you heard, was it in a Vitavox corner horn? I'm think about
acquiring or building a pair of Vitavox corner horns as I have a perfect room
for them. [/quote]

Here is the list of the thing to do with Vitavox S2 in order to use it in 4-ways installations. The S2 must not be used in 2, 3 ways systems. It possible to do with S2 whatever you wish but pretty much any other way to utilize them produces some very...

[quote user="jessie.dazzle"] If you've tried both, and decided to keep the 16R versions, you've answered a question I've had for quite a while; I too use the 16R version, but have always wanted to try a pair of 8Ms with 8 Ohm coils (should have o...

Romy Hi, firstly I have the greatest respect for you, and your beliefs,( vis a vis audio reproduction ) you are absolutely right about drivers Ralph and Thomas listened to every commercially driver , apparently some of the Japanese drivers sounded ok...

There are MANY people who would see built-in bass horns as a plus, but 99% of them will toast the Vitavox drivers at day one....

[quote user="cv"]Here's a crazy thought... have you every tried driving the S2 directly from the Placette?! I know the 6E5p does some unique things but I wonder if it might be educational.The placette has a 7 ohm Zout right? Don't forget that that do...
