I am sorry that it took me so long to respond to yours and many other questions here but unlike most of the people who have the time to post here because they are unemployed, I have a DAY JOB and have to WORK for a living. This is not a value judgmen...

Here are the horns painted...soon to leave Germany for Oz....

the blue horns arrived today....and they're all hooked up and sounding..............FANTASTIC.......!!!!!!
In 10 years of DIY audio, there's a few moments of sheer joy....tonight was one.
Will muck around with placement of h...

I was cleaning today Macondo. To clean the horns painted in texture paint is a pain in ass. The dust settle in the valley of the paint and it is very hard to clean it up. I used a hard foam-make brash and was driving the dust out by performing wide s...

Novigera, let's ignore any issues of sound quality first. A horn loads its drivers and increases efficiency only at certain frequencies. The frequencies that are more efficient are based on length, taper and size of the mouth. That means that it does...

[quote user="rowuk"] There are too many great sounding shiny horns for this to be "generally" true.[/quote]
Rowuk,
To talk about shine vs. harry horns surface is very difficult as, in my view, people who talk about it do not have data that ...

Visited audio show in Montreal. Once again realized that only horn speakers can sound decent. So I was wondering, if someone with experience could tell me the basics on horn speakers. I apologize if my question sounds really stupid, but I am not sure...

[quote user="ulf"]One advantage of the use of a phase plug in a midbass horn is that it will beam less at higher frequenzies than a horn without phase plug. If the phase plug is designed for the specific horn and driver it will help "steer" the HF.

Hi Romy,Got my new Le Cleach tractrix horns (320hz) for the Vitavox S2's. I'm x-ing over at 600hz with 2nd order 12db/Octave which I know is barbaric for you but it is all I have for the moment. With the new horns the S2s are puttin...

Hello el`OlCan you better describe "the center of the wavefront is moving backwards" ? You mean the sound wraps around the speaker differently dependent on the wavelength compared to the baffle ratio i think ?This is also true for horns (not only for...

JBL developed the PT-Waveguides not only because they are easier to produce. They also have less harmonic distortion than biradial horns. Disadvantage: They look far less funky....

…and I do not imagine the Santa is bringing me a new pair of horns at New Year. For whatever reasons people think that there are such things as “better horns”. Also, many horn people dream about “bigger horns”. Ironically I personally do not suffer f...

Jessie, looks nice. I never did it myself and can not appreciate the labor went into it. Horn-wise everything looks well- thought out. I personally would probably go for a monopod frame above the midbass horn (mergeing it in middle) as I feel it make...

Romy's quotes in blue:Daniel J. Plach's quote in green:"...The back chamber mechanism is good. Are you planning to do the same in the midbass horn?..."Yes, it will be similar, but more robust; I have an idea for a locking-type seal, which I would pro...

John Sheerin? I have come across what this character does on-line. I am not familiar with him personally but I am NOT a big fun of what he does. He moves his hands in space and sometimes as the resume of his hands moment some horn are built up. H...

I have no idea what he is and what he is looking for. He declares himself as “just an average guy in an average basement shop building hi-fi audio horn speakers from wood”. I do not even know in what country his leaves, not that it is important...

Occasionally scanning popular internet forums and looking what horn say I discover an interesting tendency. The people who fancy themselves big horns aficionado always roll out eyes and as an expression of final wisdom they express something like thi...

There is a Russian guy Dmitry Gubchenco who claims the he makes custom installations using horn-loading topology:

I am not thrilled with what I see but it was not made for me. Anyhow, it looks like the gu...

I need to say that with all huge advantages I have in my room with my midbass horns there is something that lost. I lost a great impulse response that I use to have on my old room with my direct radiating bass array covering up to 70Hz. I did not...

I was listening recently my Carl Schuricht’s Bruckner and I again noted what I am been noting for a while. I feel like my Midbass horns begin to sound a bit saggy. It is not too but and the degree of change is very minor. It is not even auditable...

Hi everyone,It is quite ironic that the day I hear from Fane telling me that the Fane 8Ms are finally ready, I should receive this update from my horn maker maestro. Russ Collinson of Layers of Beauty. Russ, if you ever read this here, please take a ...

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...

Yes, Jessie, the idea of the triangle horns with some kind of location of the drivers is what I was thinking as well. This week my attic, the walls, the beams and all the rest of the things will be expected and we will convert it to AutoCAD. Then I w...

I am on record as not liking back loaded
horns:to be effective at bass frequencies, a BLH needs to be as long
as a FLH would be; I've yet to see a BLH, with the possible exception
of the Tannoy Westminster, that actually has a long enough horn ...

I note English Mfgrs tried low power ribbon Midrange horns in the 50's (Decca, Kelly & Quad also made one!).These were probably inspired by the hi pwr prewar? Klangfilm ribbon horn (would like to hear one of those!) But, after Peter Walker moved ...
