[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...

At some point last year, after I had been offered an opportunity to buy some Vitavox S2 drivers from someone in Paris, and some S3s from Germany, I decided to approach Mike Harvey of Octave Audio, AKA Vitavox Hifi, to get some information about how I...

So in an effort to learn something about the way the 288 and S2 sound the way they do, what do you suppose the mechanical differences in the construction of each driver that causes the differences in sound as they look so similar physically?

I believe you use the laser to find out at what frequencies there are resonances and where they are at so youcan make the phase plug accordingly but like I said I know about as much as those lasers as I saw in the Tad brochure. A machinist told me on...

There is a guy named Ad in Netherland who makes looks like aluminums (but I am not sure) horns for 1.5 inch compression drivers. The first picture it looks like an exponential: W=39cm/15.4Inch. L=45cm/17.7Inch.
I do not know if Tractrix and the Fren...

Adrian,
If you are still in MF frustrations then I have something that you might find interesting. Recently I pick up in UK a pair of Vitavox S3 drivers. They out to be with original metal cones. I do not need them but the price was too good to let ...

[quote user="drdna"]Very interesting, it is certainly worth a try. Do you have the information on frequency response, impedence, etc? [/quote]http://website.lineone.net/~empson/S3.html...

My understanding : This is simply what's left of the original Vitavox. The original founder had an interst in quality audio; the current owner(s) seem to have an interst in government contracts ($?). I'm not sure, but seem to remember that the curren...

Lately the Vitavox electromagnet project looks like moved to a fruitful direction. Well, I do not know if the direction would be a real fertile but it will be going somewhere instead of talking… that is always fruitful. I have quite good support form...

If there is any info in this or another post about why the S2 is so much better than the Altec 288c please direct me. If not what makes the S2 drivers so different than a 288C? (I am talking about 288'cs that the 24 ohm diaphragms have been...

[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...

[quote user="Romy the Cat"]Below are the images illustrating how it will work at the first test-stage.

The first draft of the experiment with Vitavox S2 driver is on. The idea to use a combination of permanent magn...

Well, I screw-in today the S2 with filed-coil into my horn. I decided to drive it with 2.4A. I used a regulated DC PS and did not employ my prepared for this tusk 4.2 Farad capacitor: the voltage is too high for my cap. The current gave me a ni...

The Heil AMT drivers are well known in audio. There is a cult of people who follow them and they swear that Heil drivers are like nothing else. The Heil drivers were made by ESS, by Scandinavian, by German’s pro audio and by Russians. The do use defe...

hi alli found a company in china wich can produce the compression drivers on my request. has anyone the exact specifications and drawings of the vitavox s2 driver ? that's of course essencial to get them made. i will also send a email to t...

It is complicated. Any tweeter is different and the RAAL’s “Water Drop” tweeter is more different then others. Almond any other tweeters that I heard this tweeter has something absolutely unique- it has no annoying upper MF nose. When I asked Alex to...

[quote user="guy sergeant"]You might write a venous attack on Vitavox but it would be about 12 years too late! [/quote]
Why not write about the Vitamix instead then? It may attract an
Emm Labs Harmonizer so that it can produce music and chop veg...

Again, Romy, nothing short of amazing that time, energy and focus came together for you! And good to hear that you are still getting Music from old CDs. I hope it goes just as smoothly for you when you turn back to LPs.If you said anything about your...

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?...

I have posted this idea at the Peter’s Vitavox site a few month back but there is no activity at that site. It sucks that there are no advanced S2 users out there. I am planning to try it myself and in a month or so and will report the result. ...

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...

Thanks for the picture Romy. I couldn't unscrew the top threaded piece myself. Perhaps I was turning it the wrong way?! Any guidance you could give on dismantling the driver would be appreciated.
Regarding the active flux modulation idea; I think yo...

This is the project that I been thinking to undertake for years. I have motioned about in multiple times that Vitavox’s S2 lower region is very lucrative but unfortunately not exactly useable if the driver run all the way up, unless you are wiling to...

I put a couple days ago a silk dome tweeter in the game. I look in my storages to see what I had there among the traditional silk domes. I ended up pulling out my North Creek Music D25 driver.
