Hello, Ulf.
Interesting. The TAD1201H is 12-incher with resonant frequency of 50Hz. It has relatively low resonant frequency for 100Hz Tractrix midbass but you most like used 10” thought and consequentially shorter horn. The shorter horns beam...

[quote user="Wojtek"]and especially "perfectionists" markets like Germany. Sound is of a secondary importance. I bet the new driver from Cesarro will be field coil driver because that's what peoplewant NOW. They want "the best" and field coil is now ...

[quote user="TonyB"]Romy, what are horn flare frequencies of your horns? I understand that both are Tractrix. My guess is that the midbass is 125Hz with a sealed rear chamber and 4" throat. Correct? [/quote]They tunes for 115Hz and pushed in room dow...

Romy, what is your thought on using a Tractrix flare on a Midbass horn, Fc 140HZ then maybe a Le Cleah horn above, say 400hz. To me this looks on paper to be the best of both worlds and avoids the 1metre plus midbass Le Cleac'h horn.I am putting toge...

my wrote: "...The lower knee of the driver range is fantastic, superbly clean and this is in a way very bad as it is a clear indication that the horn is too large for the driver. I think S3 drop like stone at 450Hz but I would need something that wou...

Yes, I missed that detail. The room seems to continue to the right... so all bets are off.BTW. I noticed a Stereo Lab 1000Hz tractrix horn acting as support for the Goto expo. horn - kind of a pity because those Stereo Lab horn are very nicely made h...

They paid attention to time-alignment, good - but the tweeters location near a large reflective surface might be problematic.It looks like a 1kHz tractrix horn to me (maybe 800Hz). I have one though it's from Stereo Lab....

I shold make it clearer:The Goto was used in a Goto 150Hz horn, crossed at 180Hz.I guess that is a proper implementation for Goto.The Fane was in a 140Hz tractrix horn with a 10cm throat and a not optimised (to large ) back chamber, and no crossover ...

Thanks. It would be interesting to try these. I heard some a while back in a rectangular tractrix and I remember being very impressed. Has anyone had any experiance of these? james...
|

KeithGoto's recommendation is to buy the throat piece of a S150 horn(It comes in 2 pieces).Then have the horn cut to the exact diameter of your tractrix and have a flange welded on.They made a special adapter for my mid horn,but recommended the above...

hi wojtek!i know, with the 160hz i may run into problems. i thought about making tractrix horns or maybe go for 400x-over with the 204´s from martin. his price is really good! i would cover the horns with something, maybe sand, maybe plaster.lat...

Hi Romy,The horn is 140Hz, tractrix, with a 4 inch throat. I am certainly not looking to improve on the 8M, in fact I have one driver already, but have not been able to find another for many months, at least the usual places. Where do you see them cr...
|
|
I am not sure what you are asking. If you willing to get 400Hz horn into 1” tractrix then it might not be any controversy about the horn’s length, it is already given and the folks from lab.de will know it and will do the right length. If they have m...
|
|
Here is a homage to the Macondo, or at least two channels of it - 400Hz tractrix with S2 and a 140Hz tractrix with Fane 8M. A T350 for HF and an as yet undefined LF solution is to be added. The horns are from Stereo Lab, with the la...
|
|
Perhaps I misunderstand the unity horn, but I did not mean my suggestion to depend on summation: the idea simply is that one horn flows directly into the other, rather than being discrete; you could have the bottom or top half alone. So the profile i...

I think it's already too late for that. A man should not go around and listen to stupid horn installations which can screw him up for a life 0).Robert , can you say why 65Hz truncated tractrix and not rectangular half space hypex or expo horns if you...

I have been doing some work with integration of tapped horns. I have discovered some interesting things that are not being discussed on any other forums. I’ll start at the beginning so a full picture will be clear. At first I placed the tapped ho...

Hi Romy…and fellow audio nutters. I’ve bitten the bullet, and shifted from BLH to front-loaded. Yes, I was an idiot, a moron for not doing this sooner. My project is ‘humble’ by Romy’s standard…but I feel it meets the following objectives I h...

[quote user="oxric"] I have spent hours coming up with all sorts of weird and wonderful, but at other times too rigid systems to support the various components comprising what I modestly choose to call Le Horn (AKA Rakeshorns). I have more or les...

Hello,This is my first post to this site, which I have been absorbing for over a year.A horn project that I have been considering would include either a 1 inch or 1.5 inch throat compression driver into a Tractrix profile horn of which I have not yet...
|

Yes, it is a standard SH-50 run as Danley suggests. I have little experience of traditional horns beyond a macondoesque 3-way tractrix stack I created so as to get a feel for horn sound. I'll drop you a line about the melq builder....
|

I would definitely produce either Le Cleac'h or Tractrix eliptical profiles as these are far more domestic friendly, especially in Europe were rooms are rather small and ceilings low.And perhaps a half-circular (80/150Hz) for the same as well as cost...

This is my first horn build effort. Been thinking about this since starting to build loudspeakers and finally have a listening space big enough to support a horn system. This is where I am at now, I know there are opportunities for improvement. And I...

Thank you Romy and congratulations on your website, it just keeps getting better and better all the time.
The RCA1428 is a great sounding driver on RCA multi-cell horns. Not that I like multi-cell sound. I have never heard an original 1428 on a tra...

[quote user="Murataltuev"]So, the question is still opened: how to get 300-400hz.[/quote]Perhaps give the JBL 2169H a try. It is supposedly very good from 300Hz to 2.2kHz, but I have never tried it. Use it in a sub 200Hz tractrix horn with a 4" thr...

In my first design, I kept them all in a vertical line. It had one channel less back then. When I added the 1" throat JMLC 1000, I decided, as the tweeter operates over 9.6k, the slight misalignment may not matter. Still, I kept vary and kept the fra...

Here is my response for the Supravox 285-2000 in 110cf tractrix. I designed a sealed chamber and with the qtc 0.707 it is tuned to 160hz. However I hope the modified version will be even better!...

My thought is that you should ask John. He has the comparison, time and time over again.Horn response calculates pressure, but that has nothing to do with sound quality. Flooding a too small horn with too low frequencies is the sign of a beginner to ...
