[quote user="Romy the Cat"]I thought that the folks who are interesting where I am going with my Macondo should know that am still working with Vitavox S2[/quote]OK, I think now I’ve learned whatever I need to learn about this driver. In order to und...

I do not know any advantages because the fact that the sound softer. I personally believe that the electromagnets have HIGHER MOMENTUM FLUX MODULATION and that make them to “sit” slightly… or exactly what I would like t...

I was sitting in my fireplace room; eating my freshly cooked oyster mushrooms and listening a master dub of Munch and BSO take on Damnation De Faust. No matter how primitive the setup was in this room the experience was enjoyable even sound was annoy...

Listening my Altec 21S, even for movies, I do detect that it has some kind of lower MF problem, somewhere within 500-2000Hz. Here is the dilemma, what to do with it in 2–way speaker? Pretty much nothing… Since I use the original Altec 19 crossove...

[quote user="Romy the Cat"]
If the S2 is completely decoupled (second order low-path at 1.5kz) then the rules of the game completely changed and the S2 behaved VERY different. I will wait until the dedicated channel of my Super Melquiades will be dr...

Well, it looks I’m near finding a more or less acceptable setting for the T350 tweeter. Ironically and completely accidentally it is not far form I use to be. It is still on the slope at 20Hz (since the T350 is pretty dead at 16kHz) but now it is &nb...

I think I have too much time on my hands or use my time in highly stupid fashion but I decided to do today the experiment about witch I was thinking for a while. The experiment was “methodology clean” and lead me to quite interesting discoveries. Sin...

Vitavox S2 does OK up to 12.5K ("strong, clean and in character") on it’s center but I never use this driver pointed directly to me but rather at good 20 degree off. (I hardly can tolerate any compression driver point directly to me). At my angle the...

Romy:Going back, you said:"Vitavox S2 does OK up to 12.5K ("strong, clean and in character") on it’s center but I never use this driver pointed directly to me but rather at good 20 degree off. (I hardly can tolerate any compression driver point direc...

Well, it looks like my lack of familiarity with ribbons/planar/isodynamic tweeters made an evil joke with me as the more SA8535 tweeter getting broken in the better it sounds. As now, after near 80 hours it practically free from any negative things t...

After the painstaking setting up of the new Macondo, measuring all distance, paralleling the horns and time-aligning everything, after the setting up a correct level of the new channel’s attenuation (it turned out -2dB was necessary) I spent some tim...

[quote user="guy sergeant"]One issue that I would consider is that the Tractrix profile supposedly does not lend itself aswell to extremely low frequency horns (being too short) as other profiles in particular the Hypex (Salmon) shape. [/quote]
Yep,...

[quote user="guy sergeant"] In your earlier piece about how to use the S2 'properly' you wrote
"Whatever happens between the 400 and 2,5 is pretty much unnecessary for you garbage. So, get any known to you soft capacitor of 3uF and place it in serie...

[quote user="Romy the Cat"]Moreover, the driver has such a huge amount of the “beneficial resonance” and such a tremendous transient ability that it scare, and my system has a dificult time to handle it. [/quote] Referring to my privios post I'm wond...

I understand your position on compression and not wanting to screw up the tone. The Community M4 driver is the perfect example of how NOT to build a 4” exit compression driver. First, the cone/dome material is garbage. Neither the sandwiched aluminum...

[quote user="jessie.dazzle"] I have not heard any other systems using Vitavox S2 drivers, but I know it is possible to get the S2 to generate on-axis unpleasentries. In the case of the system I am building, one can happily sit straight in the firing ...

[quote user="jessie.dazzle"]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 me...

[quote user="jessie.dazzle"] Back when Fane were still in business, I ordered a pair in 16O (I don't know if there is a theoretical best choice between the two for horn loading... Any thoughts ? However, the 8O model will require a smaller coil in th...

Yes, Anthony, any horn by nature has what I call horn arc. At the bottom of the range the channel boost output, then the gain slowly decay and become almost like a direct radiator and then the output begin to roll off at HF by horn until the driver r...

Dear All,I wish to commence gathering the components and finding the craftsmen necessary for my DIY speaker project, but wished to bring my proposal before this forum in order to establish whether it's intrinsically worthy, and whether any simple imp...

1: If it is not patently obvious to W that Romy is far from enamored with what I hypothetically propose, then it would seem that W is grievously wanting in terms of intellect, a more troublesome failing in the world at large than errant taste in loud...

[quote user="haralanov"] Yes, but you are familiar with the compression driver and horns. How could somebody control the size of the audio window, formed by his midrange channel, using horns? If I remember correctly, you chose your Vitavox S2 driver ...

[quote user="Romy the Cat"]So, you feel that high voltage filedcoil do excite the electromagnets driver somehow?[/quote]I will not call this exitation, let say it dynamic stability.[quote user="Romy the Cat"]What voltage you feel is appropriate?[/quo...

[quote user="Romy the Cat"]Now my midrange channel need no upper range diffusion and now I feel that the result I’m getting from T350 is too soft and too transiently slow for S2. So, I kind of very mildly begin to look out there and to try top fugue ...

As I have mentioned previously I’m slowly in a process of assessing other opportunities for my Macondo, since the EV T350 driver it too soft to be paired with Vitavox S2. While I am doing it an old observation keep knocking in my head. A few years ag...

Yesterday there was the worst I can remember in my long-lasting with electricity. I mean it was not just bad it was beyond any description. My preamp has 126 steps (near a db per click) and during an average electricity day I listening it at 50-60 sl...

Years ago, the two different systems in which I heard RCA 1428s - in a fairly big warehouse and crammed into a basement listening room - used giant RCA multi-cell horns in combination with giant Ubangi bass bins, passive crossovers and vintage WE or ...
