Hm, I do not know men, but it des not work. Over the last few years I have tried the ordinal metal diaphragm 4 or 5 times and not with the Super Melquiades it is the most successful try but I still feel than it is not the sound that I would like to g...

[quote user="drdna"] It has the Magnequest DS-025 OPT, connected to the 16 ohm tap. [/quote]
So, it is 2.5K primary and you drive 8R speaker with 16R tap. That makes the 2A3 loaded in your case with 1750R. I think it is necessary to know in order to...

Loudspeakers. For whomever who follows my dairies on this site and whoever has any real understanding what makes a horn-loaded loudspeaker to sound good it is know that Macondo Acoustic System is not juts the result of my DIY efforts or the John Hasq...

First thing first. I was running under impression that the cost of Silbatone Aporia under $100K. I was looking where I might get this impression from. I am sure it was a comment at some CES blog but I was looking and was not able to found it. Most li...

Looking at the pictures of CES I came across a new Seoul-based company Silbatone Acoustics that show off a new speaker “APORIA” in Vegas. It is a back-loaded Manger.
What I read the company philosophy I was not pleased.

[quote user="Markus"]There's no plasma tweeter on the Cessaro. The tweeter is the TAD ET-703. The HK owner has a gold-coloured horn for the tweeter, but there's no plasma driver. I'm pretty sure the horn on the Lansche plasma tweeter is a good bit la...

[quote user="RonyWeissman"] I have the 515-Gs If I remember correctly, and I am trying to find suggestions on what is proper horn-loaded cabinet still. And I agree my tannoy golds so far have worked best with early 70's mcintosh 22...

Murat, that's a lot to ask from one driver. I thought that any time the "un-aided" driver craps out or acts weird, it's time to think about a crossover, and/or some sort of "assistance" for that driver. The great thing about horns is, they can passiv...

Do proper horns "suffer" from K2? Do you not think that the back chamber loading is part of the engineered concept? Are you sure that reflections from the room that travel through the horn to the diaphragm would not cause more trouble? How can yo...

Ok, I loaded the S3 driver into the new multicells, use my extra of bas sections as a pedestal for multicell, connected 2 extra bass channels to ULF amp and the multicells to full range amps with no crossovers. Yes, I got a VERY good width and th...

The stereo lab store prices seem very reasonable, considering the cost and work of molds making, shipping is something else altogether, another factor yet, but my question always comes back to the tractrix curve, there is always a loss ...

[quote user="nl"] I have used Russian high-gm tubes like 6C45 in amps before, including single-stage designs very much like Romy's single-stage Milq. These have many attractions. However, in my experience it just didn't have the tone. Jim de Kort of ...

[quote user="Murataltuev"] Now it is
clear! Thank you, Romy!Today I auditioned and measured GOTO with closed hole in
back chamber. Mid-bass completely disappeared!
With closed back chamber it works efficiently
only from 200Hz! So, I'm going to tr...

I think that I extended too much credit to them. They were saying
about different midbass and bass horns and I was under impression that they do
not let their yellow driver back loaded horn to run all the way down. To use
Foxtex with no high pass ...

Back in end of 90s, we read articles by Thomas Dunker, Joe Roberts, Bruce Edgar, and many others (some of them were designers and some of them just publicists) who were trying to persuade that horns are some kind of advantageous topology and that...

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 ...

In terms of the length of the horn, I'm allowing myself a total height of 7'6" (just below the average ceiling height of 8'). In regards to the mouth diameter, that's another matter. (It appears that I will have to build two [2] different...

John, I disagree.
No one deny the importance of harmonics and you are right saying that “If a speaker does not reproduce the harmonics correctly, then the tone is not reproduced correctly.” However you are talking about a complete speaker, not...
