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...

Romy I have not herd so much doulble talk in a long time. Some of the best sounding drivers on the market in the last 60 years, were for sound reinforcement. I do believe, in a 2 way speaker system crossed over at 800hz with a good wood horn i wil...

At the bottom of your RAAL you have Vitavox S2 driver with
no lowpass filter, right? Do you have an alternator between Milq and S2? If you
do, then the alternator has some inductance and acts and a very mild filter. Anyhow.
I disagree with RAAL an...

Klaus,
The 515-8GPH were in same scale as the 515G with slightly above 35Hz resonance frequency and 103 sensitivity - a very good candidate for 60Hz horn. The 10” throat? No bolls to go for 9”, how about 8”? I’m just kidding. The throat ...

330 or 300 or 297.875Hz... Migh all be just as interesting... Or more likely a complete waste of time.
It does not matter what Vitavox did.
My motivations : There is only one, and it is not related to the lower knee of my Upper MF horn/driver, ...

I had today a couple listening sessions with the Water Dropped Macondo. It was amassing and …. a little strange . The tweeter does whatever I was expected from my imaginary “conceptually-perfect” tweeter but it also it does something new for me, taki...

MochaMike, yes you are correct it would not be the “softness” but rather”liquidity”. Still what you are taking is applicable for the paper cone 4 to 15" drivers not compression drivers. Who knows how the compression drivers will react.
To the rest ...

I put the Super Milq and the new one-stage Milq today and was playing them together in order to see which would be more interesting. It is imposable to “compare” as is the upper bass and lover mid channels as the Super Milq has all kind of line...

Today is a “special” day in the subject of this thread – today the last waited piece of the projects – the inner-stage transformer will be shipped to me and I will have no more impediments to render the project. However, the intricacy of the pr...

I do not think that I changed
opinion about anything. I used the white suspension since my initial introduction
to of S2 and never likes any other suspensions. I do use metal suspension with
S3 driver in my Fundamental channel but is operates betw...

Thanks, Jessie. I just will buy that Beswick Engineering valve, it looks like it is the right size and it look like it will do what I need
I made some experiments applying large gaskets to cover of the back chamber. I used a gaskets up to 12 mm but ...

Jessie,
A few hints. If you are moving from Parsifal/Encore and LammM1.1 world into the world of SETs and Horn then do not be in hurry to commit yourself and do not create to yourself artificial addictions.
When I talk about artificial addictions I...

[quote user="RonyWeissman"] Got my new Le Cleach tractrix horns (320hz) for the Vitavox S2's. I'm x-ing over at 600hz with 2nd order 12db/Octave which I know is barbaric for you but it is all I have for the moment. [/quote]

Mark,
It is hard to say. I owned T90A sometimes in 2001-2002. At that time I was going through the drivers like crazy and T90A was just one of them. Looking from now I do not think that I gave to many drivers a chance as I did not “work” them trying...

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.

Listening the argument of the field-coil’s people I note that they constantly stress the demagnetization subject of the driver’s magnet, advocating that with electromagnet “the field coil will always produce the same strength now and 100 years in the...

As some may know from previous posts, I have been working on horns for the Vitavox S2 as well as other drivers (I am photo-documenting the process, as it is somewhat unusual, possibly to be posted here at a later date). Last night I was able to test ...
