Yes but.
They have a 17cm throats so in most cases it is better to get the version with 2" throat for compression drivers, shorten them for the right throat size and build a chamber yourself.

Horn maker reply

Hi Romy,

Unfortunately I have never arrived at a fully integrated horn system - but I have mostly enjoyed the attempt.  I think those who buy my horns (Azurahorn) are, like me, working on the deeper task.  I actually keep a low profile so as not to encourage demand - I enjoy making horns occasionally for the intrepid few - but dont really have the time.

I came over here to look for advice on mid bass horns.  I have found what you say on the subject to be entirely true - it encourages me in a way to find out what is going wrong with mine (you can see it on azurahorn.com) . Sorry I missed the thread while it was going on.

Thanks and best wishes,  Martin

Talking about commercialization of the upperbass horn

Hi, Martin,

As I understand you are the AU guy who makes horns? I heard a lot about you, very welcome, it would be very interesting to hear your experienced…

I agree with you: what I say on the subject to be entirely true. :-) However, talking about the upperbass horn there is more “complicated” fish to fry. Talking about upperbass horn or the midbass horns we need to differentiate who would be the user of the horn. If we do the horns for ourselves or to the “specially” paid customers then it is OK and we could go for the “right ways” to make upperbass. However, what we are trying to abstract even a successful upperbass horn’s idea into a series commercials products then it becomes to be very unattractive, as the majority of the properly made upperbass expenses are in the completely invisible  for consumer area…

Nothing is missed. The formant of this format is that nothing is missed and any worthy subject might be reinstated and continued.

New Old horn-maker in US
fiogf49gjkf0d

It looks like a new horn maker wanted to be know: the Eleven Horns

http://www.elevenhorns.com/welcome.htm

"... so.. what is a junkie?   well, I guess an example is the best way to explain...  between the two of us, we own a few drivers - Western Electric, TAD, Altec, Goto, ALE, RCA, Radian, B&C, Coral, etc, etc... and not being entirely satisfied with any of them, we are now on the long, enjoyable journey to making our own.. patent papers everywhere... busted drivers... sliced diaphragms... spliced surrounds... oh, horns.. sorry about that.. yes, and we each have the ability to make any horn flare we want.. they litter our workshops... and we both agreed on a precious few -  those depicted here... so beware, like any junkie, we want to share... if only because it allows us to feed the habit... "

http://www.elevenhorns.com/ordering.htm

The company makes mostly Le Cleac'h horns or as I call them the “Le-Horns” (sorry, Mr. Le Cleac'h – I have difficult time to spell your name). The prices are all right and their attitude to make any custom job need to be welcomed.  Looking at the people behind the company it looks like it was Victor Sierra’s attempt to give a face lift to his old company.  Generally it is a good sign – the more horn makers the better.

Now some minor criticism. Obviously they need to develop their site. They need to put in there interesting IDEAS of horns systems, not just the gayishly-glossy pictures of a few Le-Horns. The horns in there look fine but all that “fine look” will go away after the first textured paint. Then, Victor Sierra lives and make his horns at some kind of island in ocean. It was known that some of his horns were turned with “wet” wood that dried out then at the customer side with some very unhappy consequences. So, it might be a good idea to have from Victor unfinished horn, have it to dry for a few month and then to finish it.

I think if people are looking and truing to solicit themselves as horn makers than they need to offer more than juts expertise to turner horn and to dip them into polyurethane. Horns themselves do not responsible for Sound, they juts a stupid brainless tool. Unfortunately the stupidity of audio people that Eleven Horns target is so high that even if they turn horn from mammoth’s bones then it would not be an assurance that people will be able to use the Le-Horns beneficially.

Will the Eleven Horns become as a some kind of new center of horn turning in US? It is hard to say. Jeffrey Jackson is behind the project from the US side (probably as a reseller). He is an interesting fellow with potent ideas but who will be the new customers?  10 year ago Brice Edgar’s shop was THE place for US horns. Brice is a talented and knowledgeable guy but who was his customers? They were explicitly audio bottom-eaters and the audio- douchebag of all strains.  Will, the Eleven Horns nurture their own breed of horn users? I do not think so, but I wish them luck.  So, far from what they have expressed at this site I do not see any offensive intent.

There is (or was?) a Speaker builder in South Korea I think, Mr. P.Y. Parks. He made the Koechel K300 Horm speakers.There was a report in Sound Practise some time ago. I heard, he is still active, but I have no more information

No-nonsense Bentwood Horns from Canada.
fiogf49gjkf0d
I made a few calls to a few horn makers with a perspective to build for me a substitute for the horrible Altec 19 horn.  While talking with people I was given an interesting lead about the guy that I did not know. He is a Canadian and his name is Andrew. He is not a Burger Kind type of horn-sweatshop. He built horns for himself and does it for occasional customers. He does not advertise, no involved with any groupies or interests coalitions. He is private parry who can make horns. He makes only rectangular horns and his prices are reasonable.

I have 10 min conversation with Andrew. How many times I concluded that this or that audio person was idiots juts after a few minutes of conversation?  Ironically with Andrew I had absolutely no need to show of attitude as there was absolutely nothing BS, showy or just plain stupid in his wards – a very seldom quality in audio person. The guy knew exactly what I need, knew how to do it and passed as few comments that indicated that he has bra and know how to use it, also a very seldom quality among audio manufacturers. Andrew sounded relaxed and confident – a very pleasant feeling and I am kind of sorry that am not ready to proceed with my Cetla Ledom project now.

http://www.bentwoodhorns.com/

Anyhow, here is another Horns maker who is very open for custom projects. I have no idea what he does and how good what he does but the initials sentiment of mine is very positive. If I go for that 33 by 11 Cetla Ledom MF my own custom horn then I think I will recruit Andrew, but I have no decision ye it is will be THIS type of horn…

Thanks for this link...

... from Onafets Ollecnotreb, Roman;-)

I agree Andrew's approach is more relaxed and MUCH less self-hyped, deal-only oriented than the average audio chap...

Again, thank you.

Jzagaja, a wonderful document about the La-horns:

http://www.autotech.pl/pdf/audio_en.pdf       

Are you behind the autotech company? Are you just make the MF horns of are you trying to build compile systems? Anything more interesting than 2-3 channels?

Position explained
fiogf49gjkf0d

Hi Romy,

I'm Autotech (Lukas Lewandowski) friend who manages technical correspondence and do design part. Personally I'm interested in all horn designs down to 20Hz and I do see some interest in multi-way horn designs from eg. Hungary. IMG_3508male.jpg picture shows my system. As you see Autotech has all axisymmetric JMLC horns and you can easily built 3 way system down to 200Hz (1 meter horn). Our limit is 2 meters. Within few weeks I will get OS waveguide cabinets which I believe have wider sweet spot than usual horns.

Polish horns, a quality product would you say?
fiogf49gjkf0d

Hi Dominic:

I hope you may be able to oblige with some additional comments on the specifications of the horns? What's the thickness and weight of the horns?

What about the prices of the 420Hz and 600 Hz horns you mentioned above?

Do you know what's indicative price for 150Hz horn? Will that horn be thicker than the other smaller horns?

Kind regards
Rakesh

A Russian Horns Maker.
fiogf49gjkf0d

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

http://www.audio-tube.ru/

I am not thrilled with what I see but it was not made for me. Anyhow, it looks like the guy makes everything from front end to acoustic systems.
