I suspect that the 8" and 5" cones and 1" compression driver are in the Danley Signature Synergy multiple entry horn. This creates a physically phase aligned point source above 45 Hz and probably a bunch of diffraction. The double 15" woofers are an ...

Dominik, in terms of technology advancement, it seems their new driver is better than their other models. But despite this, I’m not sure their transducer engineer knows how to make the drivers to be valuable in terms of sound/tone. I’m saying that n...

Decoud, I do reject any speculations about flux modulation in compression drivers as I do presume that it is absolutely negligible. It is like using a SS amp with ultra low output impedance, to drive a ribbon tweeter and to worry about return current...

That is the thing exactly, my upperbass solution has the same output amplitude as the compression drivers I am using, IMHO resistrors are the devil in xovers, they kill all sound. Now the difference between 109 db and 110 db can be overcome with c...

I am missing something here, because to me this looks like a compression driver with specs that indicate it would best serve >10k Hz, yet it is... a compression driver. Maybe if it was backed down and run parallel with something more delicat...

[quote user="Romy the Cat"] Make an experiment, and I will simplify the case quite assertively. Take a typical compression driver, cross it at 800Hz, second order and load it into a proper contemporary horn (Tratrix or JMLC) of 300Hz. Listen that hor...

Some thinking about Romy's Injection Channel (see the following thread) : GoodSoundClub - Romy the Cat's Audio Site - The "Macondo Ultimate" MK-XXVII, Revision 432 ... brings me to a question that I've had a for quite some time: When aligning a "norm...

I also disagree. You circumvent the whole theory if compression drivers. The whole point in a compression driver is that anything in back chamber is irrelevant. Haralanov, all that you need to do is to make your own experiments, the practical exper...

[quote user="Crow"]The sound changed.[/quote]I do not think that sound changed. Those speakers have most likely MF compression driver with horn. When the camera shot from the back of the speaker the sound does not change. I mean is changes slightly n...

[quote user="gordan"]Roman,I don't think I've ever read your explanation why not 2482? We are all on a holy grail path to find a (somehow) available good compression driver that can go down to almost 200hz in domestic conditions and there are not man...

Yes, Rulit does try to push envelop of something. He does exiting projects but I do not know how all of it manifests itself in actual results. I said that he pushes the “envelop of something” as I do not know what this “something” is. I never h...

[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 ...

it doesn't appear to me that Lowther's own designs hold any real potential.As some might figure, i'm partial to Voigt's original intentions, and i think those have been covered over.I post now because i had an idea.I see the lowther as a pseudo compr...

Oliver,
It might be anything including electricity. Generally compression drivers are very much vulnerable to the electricity problems, muck more than convectional drivers. Let pretend that distortions in powers lines are responsible for worsening o...

[quote user="Jorge"]I guess it would be simple enough to add a couple of inches in order to bring the throat down to 4" in order to try the Studio 8M. I have already reduced it temporarily to 3" in order to try the JBL 2490h compression driver. ...

[quote user="haralanov"] Yes, you are right. Power – you have almost unlimited power. Dynamics – you have as much dynamics as you want. But there are a lot of associated problems with that kind of dynamics. The following illustration is taken by ...

I have just taken out of my system a First Watt F5 clone Tim Rawson amp, It was substituted by a Telefunken PP amp with 6AQ5 tubes. Let me to explain.
My system consists of 6 way horn loaded speakers. I have a round Tactrix...

Mr. Lang, very interesting what you are talking about cones. Does your company or you personally have a capacity to do custom aluminium Görlich–like cones by customer specification? I ask because I have some interest in the subject. I was approached ...

I see, I misunderstood you, Robert. I was under impression that you “speak horns” and that you have lived with variety of horn-loaded playbacks and ideas and now you have decided to go for making your own compression drivers. If you did not and it wo...

[quote user="Romy the Cat"]...but I was wondering how the length of the port and the most important the proximity of it to boundary affects sound. [/quote]A general rule is to keep the end of the port at least twice its diameter away from walls....

Josh, I am not sure what you want to say. If you looking to name the reason why you like the sound of Gotos then you are guessing as much as anybody else. I can tell you even more. I very confident that the Goto folks themselves are guessing. I do no...

Continuing to harass the readers of my site and myself with the good news about the performance of my SA8535 driver I would like to post a very educational article about the subject. As I told before, being familiar with sound of ribbons then never i...

Romy,It is interesting that you say that the problem is well known. I discovered this application in 1972, while trying to come to a solution for the sonic insults being supplied by a pair of Ohm F speakers. I eventually got them to act somewhat as W...

What will be your suggestion for upper bass
channel using compression driver ? [/quote]
I do not use compression driver
for bass channel. I would like to have my system esthetically balanced, to get let
say 120H...

I was slowly looking for a compression driver that would go in my Fundamental Chanel down to 200Hz. The YL Acoustic 550N attracted my attention. Then I realized that it is the narrow throat type of the drivers, aka WE555, not exactly that I would...

[quote user="Romy the Cat"]You do not see any explanation is because you are not accustom
to think about explanations but wait that explanation will be brought to you.
Here is a homework to you: provide answers to the following questions:

Well, I think it was juts a bad translational as some of the things they said in there are so off the wall they it sound as they were written by a 10 years old. I more interesting what 3” compression driver they used… I wonder if it is 3” exit, or 3”...

I have seen Beyma rewrite their specs when they redo a driver and even add a letter to the driver for that change, even if it is the same driver.Now I have seen variable FS responses form different drivers of the same model also. I was joking with a...

When many of your will experiment with building and listening your own horns and spend countless amount of time by sketching a configuration of your new horn assembly you then might come to an observation that Macondo Upperbass topology is very s...
