I'm going to try and build a Melquiades type amplifier (with some help from friends) following the advice given above to make it as simple as possible. I could spend more money for "different" transformer, but I will ask you for advice on...

For all S2 fans... please be aware that seller "milesvintage2007" was claiming to have found a load of diaphragms in an old cinema (yeah, lots of those running Vitavox in Hong Kong, I'm sure...*)Even forged the labels on the tins... He has since remo...

I have two pair of the old 15" Vitavox: two drivers coned as K15/40 and two as another less common variant with a softer suspension and lower Fs but I cannot remember right now the name. Shortly, a brand new pair of K15/40 shall arrive along with ...

I would start with the freq from 60 hz to 10 khz. If you already decided to use the Vitavox S2 and AK-151 get those and start using them in that range, it will take a long time to get them perfectly settled. Will you use the AK-151 inside a b...

GOTO make me feel it renders the musicians like they are ghosts. They are all in there but floating and slightly transparent.I think the reason for that is GOTO does very interesting things at highs and mid-highs but while it goes down at the frequen...

I recently completed some upper bass horns which I'm now enjoying very much. Sadly I lack the skills of someone like Jessie so my efforts are crude in comparison, but they are working well for me which is the main thing.I already had some old frontlo...

I am out the door, just wanted to mention, it is my understanding that only one of these was meant for a horn; the other is a direct driver, like the original 515.I assume the celebrated "slotted" Vitavox horn is not the same as the one and only Vita...

[quote user="morespeakers"]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 ...

The recent events in my playback made me to think about he new prospective duty of tweeters. Since the Super Melquiades was enlisted for duty the Vitavox S2 got it’s own dedicated amplifier channel and stopped to “see” the coil of upper bass driver. ...

There is a pair on eBay of Vitavox S2 drivers with 400Hz Tractrix StereoLab horns, the item 300372010439. I usually do not like to make comments about eBay things but I think it begged to be said. The driver and the horns looks fine for 1000Hz channe...

It is really amassing, how Melquiades takes recordings apart, literally and rebuild then in own manner! I never see anything like this, and I believe that I have seen something in audio.
Melquiades does something entirely unprecedented: it retrofit...

OK, I guess I am a little confused about how you get * enough * acceptable tweeter-less sound above 10k Hz that you can wait to cross over at 13k Hz. I don't know the Vitavox S2. Are you saying the S2 goes strong, clean and...

Romy,I am very interested in this thread as I have heard the latest version of the speaker "eufrodite mk IV" . I do not think any of your objections would be changed by the latest version as he is now using push-pull array of beyma 8" drivers up to 2...

R,More interesting observations there. Your Lowther thoughts are similar to mine - I always wondered what a lower flux version would sound like, but non-horn loaded and whizzerless a la Horning. Even got round to obtaining some magnet-less motor...

There are many threads on my site where I covered the subjects of Tweeter for my Macondo and particularly the moment of integration the tweeters with Vitavox S2 compression driver. Since a few months ago I altered my idea to use the EV T-350 tweeter ...

Wow, I mean really, really, really, really, really WOW!
A week ago I converted one of the Super Milqs to 5:1 loading and yesterday I converted another one. I loved what the last week converted amp did. It was very nice but today I put the entire sys...

[quote user="Romy the Cat"]Hm, interesting, I did drop the crossover frequency but I do not like the result. I was driven in different configurations and experimented from the current 13kHz to 7.5kHz. As soon I drop below ~ 11.8kHz then the overl...

[quote user="jessie.dazzle"] The AK150 and 152 are not new creations dreamed up by Mike; they were made back in the day by Vitavox but nobody ever talks about them and I have never seen either. See the Unofficial Vitavox web site; AK150 = Catalog...

[quote user="de charlus"]Romy, do you have first hand listening experience of these YL drivers? If so, in what sort of installation? [/quote]
Nope, I did hear neither YL drivers nor ALE driver, as least consciousnessly.

What I found captivating in the story of the Living Voice speaker is the he motivation of the Living Voice people to go from their former model to this new one. This itself. is a very interesting to me subject.

I tried the driver and generally I do like it’s sound a lot. It more sophisticated then Linaeum, it is more noble tonally and alike the Linaeum is seamlessly melts with Vitavox S2. In fact I am developing recently a theorem according to which a compr...

Here are some responses :
1) Rubber gaskets :
Maybe it is not so important to have an “air-tight” seal (???). The rubber gaskets are there to seal the cover to the rear chamber...

It is not about “how low can the 600hz horn go before running in to problems” but rather a specific if of Vitavox S2 driver. The S2 with plastic suspension has secondary resonance at 1250 cycles (you might read about in details in my S2 thread). So...
