It is a shame that I keep finding threads about a 300Hz compression driver channel, that ends abruptly. I have been trying with a not-so-exact Goto S-150 replica (~1.7m deep, 75cm diameter mouth), and I know of another fellow in Sweden who tried the ...

[quote user="drdna"]Is it possible that a simple experiment can be done with cassette players and the Dolby filter since this equalization affects compression for example? Adrian[/quote]If you are referring to the "soundstage" quality of such playbac...

What really pisses me off is that my second arm/cartridge has a very strange effect that I did not see neither in this arm (Micro 282) not in this cartridge (Ortofon SPU Classic). I am taking about dynamic compression. In fact it is very seldom you c...

A Seminar presented by Greg Burnett at Audio Fest 2004, Colorado Audio Society

Why are audiophiles interested in FM radio? Because the quality of FM audio was satisfying until stations began to compete with each othe...

[quote user="be"]Both the Fane and the Goto where used as compression drivers, so there where no principal differences of use. [/quote]
Wow, who made such experiment? Bring this person to my forum, it would be interesting to interview him! I still d...

It took for us, for the people with brains and ears, a few years to explain to the foolish audiophiles the artificiality of their soundstage objectives. Six years ago when I was tiring explaining to the audio-zombies that soundstage is juts a surroga...

Upper range effect is amassing, though not much different then with other regenerators. With PS Audio’s Power Plant the compression at MF-HF is also reduced or eliminated and that ugly heavy dense pressure blanket got lifted. The Power Plant while do...

[quote user="decoud"] If a magnetic field is static, who cares how it is created? Isn't the main potential advantage of electromagnets one that no one has explored at all - the possibility of modulating the field strength in direct response to the au...

I'm of the opinion that listening room aesthetics play a big role in enjoying music at home. This is self-evident, but over the many years playing with audio, my listening room has become incrementally cluttered with "audio detritus". It's ugly and...

To assess how far audio imaging from sound of a ”live” musical presentation we need to subtract visual experiences from perception, including the long-lasting visual experiences. I would agree that focusing ONLY on imaging can lead attention off beam...

I have been searching for a good discussion on this subject for a while an yet to come across anything that really explained this: What are the causes/factors of compressed sound? I know it when I hear it, and have heard this phenomenon attributed to...

[quote user="Rewind"]You said are lucky to get hornloading down to 150Hz. Then I guess you suggest you will end up at maybe 175Hz. Hornloading a compression driver down to 175Hz is not too difficult and the horn will not be larger than the Avantgarde...

[quote user="Romy the Cat"]
One more tip. The “least dynamic compression positioning” mostly managed by upper bass and bass channels while in the “imaging positioning” the MF and HF channels play more dominating roles. Therefore, if you use a typica...

The initials post was the body of email that Kostas sent to me and considering it’s format he presumed that I will me post it on my site. So, I did it (with his permission). I ran all those tracks once (some of them just a few seconds) and below is v...

[quote user="Murataltuev"]Is any
technical background behind the statement that 4" driver can't
operate in 300-1000Hz because resonance is too low ? [/quote]
Well, you need to define what does it mean “can't operate”? Anything can operate anywhere...

Rewind, the explanation if my injection channel does is well described at this site. I do not own a copyright over injection channel nether term not concept. You can use your injection however you wish and call it whatever you want but what you do is...

It is depends what kind horn it is. For LF horn the resonance should not be “an octave lower then lowest frequency you can realistically get from the horn”. In fact the common way is to much the assembly resonance to the horn cut off by squashi...

[quote user="Romy the Cat"]Ok, let kill the subject of Oleg Rullit out of this thread. Rullit has very little to do with horn and consequentially with compression drivers. Sine this thread is about MF compression driver I think there is no reason to ...

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 ...

[quote user="Rewind"]Hi, I am slowly building my own Macondo. I understand why the injection channel is there. It brings some kind of softness that the compression drivers lack. [/quote] OK, but it is not how I feel about the service of injection...

John Hasquin showed up a couple days ago and suggested that many of modern compression driver manufacturers design thier products to get the "best" publishable parameters while completely disregarding any basic horn design rules and actual sound resu...

Romy, when you mention "dynamic sinking" of ribbons are you speaking of sub-8k Hz use of powerful ribbons like the Water Drop compared to 109 dB efficient compression drivers, or do you notice this dynamic sinking no matter how high you cross ov...

I have not heard the Heils with all possible amps, but to my ears they are equally unequivocal with Tone and Dynamics, once their (rather low) "threshold" is reached. At least with respect to dynamics, this seems like the opposite of what one would ...

As things stand today, I believe that the biggest gain in quality is not to be had via the pursuit of higher resolution formats.A friend of mine who works for a large media distribution business (like Amazon) recently gave me a bunch of sample CD...

[quote user="anthony"]It is a compression driver with an 8" cone. If you want authority at 300Hz you will need diaphragm area. The Fane Studio 8M that Romy and plenty of others use for 100Hz up to 1kHz is an 8" cone driver on a 4" throat with a clo...
