Paul,After looking at some photos of Stock Altec horns, though they appear reasonably stout, I can believe they would still resonate when excited by sound pressure alone, as they are still on the thin side if left as bare metal.See them here : http:/...

" Every comment about the sound of any device has a deeper reason and it can be great fun to try some of this stuff out instead of just believing it.I personally believe if a absorptive surface is on the inside of the horn, the pressures in the devic...

Hi Be,the thread is about the "bad" reputation horns have with "audio" people. Applying liquid dynamics gives them more fuel for the fire, that is why I avoid using stuff that really doesn't apply. We have no real flow of air or "turbulence" in a hor...

Hm, I like the Cessaro thinking a few years back and I love it now. A very good move with this “Liszt” loudspeakers, even I am against the idiotic tendency to grand to the audio element the composers names. Take a look what Cessaro did. A tweeter, p...

Romy, I'm very proud that you are following me and commenting my achievements.I just don't understand why you are doing it in a manner that you are the one and others are idiots and morons. If you don't understand others, you can ask them questions. ...

Why not enclose it in a horn shape? After all, it makes sense for the facing surface to be circular rather than square, and a cone will have the best structural properties, as well as having the closest kinship with the rest of the stack....

Yes, my idea is not just optimistic but unrealistic. Returning to the question of technology for mass horn production, what about having an armature made of a coiled steel ribbon, the coiling being perpendicular to the plane of the ribbon. Thus the c...

hi jessie!why you dont make it from carbonfiber on a foambase? carbonfiber is much easier to work than glassfiber and of course gives stiffer boards. im also just working on a "surfboard" horn, but i make the bent sides with layers of depron boards a...

A site visitor pointed me out the I never made an intended write up about the David Haigner horns. I just forgot about them… OK, let analyze David’s claims and his Alphahorn design. I would say right the way that I do not like the Alphahorn’s id...

I had a number of discussions about ribbons loading into horns and I generally do not welcome this idea. There are a few reasons why it never work properly and one of the most convincing is that in order to develop enough output from a ribbon you nee...

I see, this is very different question then you initially posted.
Ironically the subject was discussed years back what I was fighting with S2’s “fuzziness” at very top.
I still do not feel that there are any 'rule of thumb' in it, there are...

Speaking about the interesting surface finish. I have seen a
new stimulating idea that I call the Scratched Horn. I do not know how much
practical effect if has but it shall not be bad. Let pretend that it is not a conical
horn with even sides but...

Romy If you would thank about what you are building and what it does, you would grasp the concept of my thanking. You have a 7inch hole on your bafflle with your woofer on the back side of it in a sealed box. The only...

The surface of my fiberglass horns is quite rough. The mould was sprayed from a distance with some water based paint - so it all landed in fine globules. Maybe this is too fine a rough texture though. I like the idea of thick artists oil paint…

Yes, Petar
I would agree with the most but with horn-loading all compromises suddenly do not get evaporated. The horn is not a panacea as the horn-loading is basically as well bandwidth-limited. In fact for objectivity sake I might say that the dire...

Paul,
I have been working with trumpets since 1966 and horn speakers since 1975. I have built both and am pretty familiar with what they are, the similarities and the differences.If I had to pick THE major sin when thinking about all of the horns th...

I know, I know, I know…
Any person who in one way or other practices horn-loading loudspeakers has a wet dream about bass horns. Here and there people built them. Here and there you can hear the assuring and overconfident statements like: “the...

Reading how you plan to go about making this horn, I offer the following (this first one you probably aready know):Make the outside of the mold in quarters or thirds and hold it together using fabric straps (not bolted flanges)... If you make it...

I still do not know if it will be doing at in my attic and I already bitch that I do not like something. Well, it is me… Considering the cost, objectives and the level how my midbass horn will be implemented (if they will) one could feel that it will...

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...

First off, I will point out that neither Silbatone nor I claim or agree that the Aporia horn is a point source, because clearly it is not. The sound comes from two "areas" but even that is not a particularly useful notion.Although some do make that c...

Dominik, Jessie is right - it is irrelevant the precession of your profile if you horn does not go to high into HF. The LF gain of upperbass horn happens in the first half of horn anyhow. I do not insists that I am right but I have a hypothesis that ...
