Thinking about my Vitavox S2 “fundamentals channel” I can’t stop think about my hypostatic view about the horns. Year after year I was mucking what GOTO does when they introduces a horn for a couple octaves. Ironical now I am truing to do the same fo...

Hello Romy and everyone here, Thanks again for your thoughts on the large horns. It seems best to start a new thread, as previous threads dealing with the "10-Footer" originally began as discussions of other subjects. Romy, you may want to move previ...

Chirag, First off all you have to define what do you want from them. If at this moment you’re looking for something within $700 then very next year, when you finish you medical school you will be searching in very different price range… :-) Now a lit...

I am sorry I do not want to pollute the PP2000 thread with battery options.Right now I am in the process of testing a lot of different comercial amps to see what I will stay with, or which route I will be taking with my system in the near future for ...

I spent many hours listening and experimenting, trying to change the signature of my mid-base channel. Everything that I'm trying suggest me that I am in at very right direction but I am still not server I would say freeze the system and do not t...

There is a new company out there that makes horn-loaded acoustic system. I know a guy who is involved, I presume he is the owner or one of the owners, but I know very little about the design and the sound of the Sadurni Acoustics. So, let see wha...

Although all of it has no relation to digital crossovers but still:

Here are some real world measurements made at the 2007 NYC sub shoot out. The distortion numbers and characteristics should help us understand the difference between tapped horn distortion and conventional front loaded horn distortion.

I did not try to measure it. Can anyone confirm the following : I assume this parameter is most easily determined by playing a series of tones at constant signal strength (volume setting) whi...

A friend of my after reading my comments about the EdgarHorn installation in Vegas (in here) asked me why do I think the bass in Bruce’s room behave as it behaved. I tried to think about it. Some of those thoughts intersect with some other projects t...

Similar to the famous sexist tail that women can be only ether pretty or smart the midbass horns unfortunately behave in the very same way: they can be only nicely placed in a room or they can sound good. You want the horn to place in a specific ...

[quote user="Murataltuev"]Romy, thank you very
much for very detailed explanation of your horn theory. Let me present some
doubts about it. From physics basics when we have more than one springs
(suspension, throat resistance, back chamber) we can...

Hi Romy,
been reading you for some years now and 99% of the cases agree with your judgments (and sarcastic criticism).
Some data on ANIMA.
The bass is an exp horn tunned to 50Hz using the floor as a virtual expansion of the...

It is not a secret that my short interaction with Murat and
my observation the progress he has with his playback made me to feel that his
is an idiot. There is nothing new in it, most of accidental audio people are
idiots. Nevertheless, I think it...

[quote user="tuyen"]When i change the cutoff of the 505tt to 200hz and 250hz, I experience that same 'hole' you mention about. Hence why I was questioning if it is the 160hz le'clech horn causing this and if using the goto s150 horn with it's di...

During the 2002 CES, late at night, a friend of mine demonstrate me something that was tying to address for a few years. It was a very different “tone” form a loudspeaker or I would rather say a different relationship between reproduced and auditable...

Romy,
[quote user="Romy the Cat"] Remind you that horn
not only does that but it performs acoustic transformation gradually. [/quote]
Yes, I do
agree with you about that. From both theoretical and practical point of view it
is 100% true. But...

Thanks for the detailed answers. I will explain my setup.You are right about the dipole bass correction instead of the injection channel. Since I am waiting for both a subwoofer and the Fane Studio 8M and their horn, I am using the 12" as a b...

[quote user="skushino"] Edgarhorns weren't an obvious choice. Many horns never worked for me. The Avantgardes left me cold. So did the single-driver crowd (I just don't get it....), Altec VOTs, PA systems, etc. But there were some systems th...

Yep, indeed, it looks very nice. The 8 sections of bass line
array look visually slightly overweening but I think when you put the upper
bass horns in place it will visually balance the things out. I feel some sort
of envy to the way how you plan ...

Thanks for the kind words Romy. I am enjoying taking my time with this project and getting things just right. It sure helps when there is little development involved, just duplication more or less. Development may come later as I impose my exp...

My primary
interests (when I do purely technical listening) are in the field of psychoacoustics
and the last 2 years I spent a lot of time investigating how the brain reacts
to differently arranged sound sources. The interesting thing is that the ...

This week I will be trying to address why the Milq midbass is clipping. This is very interesting one. Currently the Melquiades LF channel uses an output transformer 700R to 5R or 11.83 to 1. I thought before that I have much lower ratio, like 5:1 bu...

Here is a good illustration for people who do not get it why La-profile is suck a damn idea with lower then MF channels. There is a guy in AU who makes the La-profile horns from some kind of plasmas and sell horns separately, not organized into c...

Thanks for the thoughts on driver impedence.

Hello Malinowski,
Sounds like you may already have the necessary experience in working with plaster, but in case you're not used to making anything this large:
For the final horns, especially if they are large, use hard modeling plaster. My up...
