It is not surprising that the subject of horn is as screwed as the subject of drivers. It is understandable as driver must be made for specific horn loading, not one make drivers properly, so what the horns are made for?
A horn is a very simple dev...

[quote user="RonyWeissman"] 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. [/quote]

On the cheap:A few renditions ago you showed a "T" section for the main vertical menber, and this would allow you to use thinner stock without the lateral or torsional issues the nominally-two-dimensional "sail" would otherwise engende...

somehow i missed that moment in macondo development when you introduced S3 as a low mid driver so this came as a surprise to me - what i remember is that you didn't write so favourably of S3 back in 2004 due to its ceramic magnet. but it's good t...

Translation:Rottbull seems to want T/S parameters for his RCF N850; I'm posting a link to a T/S database which has info on a lot of RCF drivers but not the N850 (it's a compression driver); nevertheless, it may be of some use to him and certainly...

Just new to this forum and there is so much to absorb.. One post I read suggested that horns be constructedwith dimensions to suit 1 oct. below the lowest Freq. to be used. I know that Mr. Le Cleache favours this ashe says the group delay is bette...

Steve Schell and I are currently using Le Cleach horns in our system, The more I listen to them, the more I like them. They sound slightly less directional and beamy than a tractrix, and overall an extremely pleasant sound. W...

The biggest event in my audio 2007 was Romy's visit/tuning of my system, and the following exchange which ended up with a revelation of how shallow my understanding and practice of audio/music was. It ultimately seems to come down to the a...

It seems pretty clear that what we do not have here is the proverbial "all-out assult on the state of the art"? For one thing, this requires a dedicated system approach, and when was the last time you saw anyone do this?&nbs...

Robert, G10 has no special damping properties that I detected. In fact it is some kind of plastic feeling material. It is “filament glass cloth material with an epoxy resin binder”.

I have found 30ppi renticulated foam in an online aquarium shop and ordered it. It's specs is the same with what Geddes used as plugs in his horns. I will try that on my cf1400hz le cleach with varying depth through layering. First just a thin layer ...

N-set, my primary reason for trying to run tubes "conservatively" is only because that's consistently what has worked best for me over time. Or, put another way, I really like to be able to "tune" all my active gain devices according to sound. If y...

Romy,If you use the plastic surround S2's from 500-5KHz won't you still have the bulge that concerned you at around 1.2K? I thought you suggested that the metal suspension units didn't have this bulge.Otherwise it seems a nice idea, albeit a bit expe...

Hi Guys,An idea I've had for damping thinner horns in a more or less aesthetically pleasing manner is to house the horn in a Sonotube rigid cardboard cylindrical concrete former, and then apply the desired damping material inside the Sonotube.&n...

Romy, for one thing, you are still talking "best possible sound" in a very literal way while most other people are merely working out one or another acknowledged compromise, or they are hoping to make their system do an even more spectacular renditio...

With the Le Cléac'h horn spreadsheet you can design allmost any kind of horn you want. Short and wide, or long and narrow, or anything in between.
cheers ;)...

Jessie, we keep meeting at the same intersection. Like I said before, I agree that direct radiators suck, for all the reasons you cited. But if what you say about horns is strictly and completely true, then does it not follow in spades at ever lower...
