Thank you Ulf and Jessie,
I can't wait to get this started. Jessie I am going to send this plaster spec to my supplier and see if I can find something close..
In the past I would use plaster for creating a wax form.. then put the wax form into a s...

I'm very inexperienced but I still try to observe things around me carefully. Here's what I'm getting at what can be potentially pretty good.. Well, all I can really say is I've been mostly interested in the design implementations of companies such a...

Wonderful horn, Chris. 160Hz is very-very interesting size for using S2 at it bottom knee for a lover mid-range channel. I when to 250Hz (I did not go lower because some my own reasons) but I think the 180Hz should the perfect frequency. With damping...

Hi there
I can see Romy's face when he's trying to figure out Martin's time alignment strategy;0) I have Martin's 204 Hz horn with Fostex 208 E Sig. These horns are to be big to properly integrate with anything. They are OK with Fostex Lowther drive...

Jessie, 45Hz horn with 6”-7” throat around AK151 driver is from my perspective is the best thing might be theoretically built around a cone driver. I really envy of you and if I had room I would unquestionably go for it; this is why I keep a pair of ...

hi romymy goal is to design a hornspeaker with drivers, that are today commercially available, s2's are not.tomorrow i get my bms horns from bd-design, then i can say something abought them. as they are coax, with tweeters, i did not design a t...

There is a US company “Acoustic Horn Company” somewhere in ... , that makes, as I understand, only metal conical horns. The company, owner Bill Woods presents his motto as “Horns based on the quality and lost engineering of the past”. I al...

This makes a lot more of sense to me. I understood you wrongly and I believed that the product "as is" and a priori can be interesting as a whole. I think that the design is interesting for the horn implementation, the horn themselves (look quite sol...

[quote user="Romy the Cat"]The biggest problem that usually people face when they listen the middbas horn is that people tend to make the middbas horns too short. In the short horn the driver shot right through the horn and the LF go not “get loaded”...

Hi
Some loose thoughts.....
A system where each amp-driver-horn-room interface are designed to work together as a unit in their respective frequency bandpass...
They each have to be optimized to work in their respective bandpass,
but at th...

Sorry to steer away from Harley, but have you Horn guys ever tried different flare terminations? That is, the boundary condition where the mouth and room meet. I once saw some interesting stuff done on large radio antennas that improved g...

Hi
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 ;)...

Hi
I am not using Le Cléac'h flares myself.
But his aproach to designing horns is interesting, I think.
I did make a Le Cléac'h horn a couple of years ago,
just for testing. It sounded very good.
cheers ;)...

You have identified the tricky parts -the transistion between the front and back horn as well as the throat of the front tractrix horn. A one to one throat with the front horn works best with my coaxials and a short 1.25" straight 'ring' ...

“All speakers are equal but some of the speakers are more equal then others”
The more I exposed to the different loudspeakers, the more I’m learning that the horn-loaded loudspeakers are the most interesting creatures. Nope, not because they might o...

[quote user="skushino"] • total horn length (incl. back chamber) shall not exceed 1,00m • the horn shall have conical approximation of a hyperbolic flare contur with m=0.6 • the horn shall have a 5/16 mouth size of a free space horn •&...

Allo Romy, I have no idea about the above - my gut feeling is that the required thickness of material would be too great, still, I bow to your experience in S2 mods. I just wanted to mention something that came to mind that might be of interest: I re...

Yes, when I move the drivers or for that matter if I move my listening position, I realign.What I hear and measure about the drivers relative distances to each other is this. When I first set up the drivers, one horn ended and the next one started, t...

|
Romy, thank you very much for very detailed explanation of your horn theory.Let me present some doubts about it. From physics basics when we have more than one springs (suspension, throat resistance, back chamber) we can consider it as one spring. Th...
|
|
Hi Chris, all Allthough most of the work is done by the compression driver at 5 K , I would still use a proper horn, a horn that loaded the driver down to 2500Hz would be minimum IMHO. You can still use a Le Cléac'h horn if you wish. ;) cheers ;)...

Looking at the variety of exponential, parabolic, conical, tractrix, hyperbolic and whatever ales horn profiles out there I was thinking that we probably incorrectly approach the entire subject of horn profile analyses.
We listen the horns and we fe...

Hi
[quote user="Romy the Cat"]
Dose it means that the “ultimate horn profile” would be a profile that would be a DIRECT AND FLAWLESS CONTINUATION of the GIVEN SPECIFIC DRIVER?

Actually you can make a new driver throat to m...

Yes, the similarity between the horn system and the Baba-Jaga hut on fowl's legs is uncanny. The system might be only loosely based on text book principles, but did you notice the use of cotton isolated wire connecting the speaker syst...

Even though you asked Romy, let me add my informaton. B&C makes very good drivers, but they will run you more than $1000.
Good luck with the frequency response in your new experiment, though I have no doubt you will get great dynamics.

You can improve the vibration decoupling by lessening the weight on the horn mouth edge.
There is no need for the edge of the horn mouth to bear a great deal of the weight of the heavy end of the horn, although that seems your current plan. Th...

Ok, here is another subject. I feel that I kind of screw it up as I did not foresee it in my planning. What I need is to add some decupling devised to my horn in the location where it will be mounted to the surface of the house frame. The horn will ...

I just wish before I start my project I read a few detail descriptions of the similar projects. Unfortunately they do not exist and I well understand that my project is in away an exemplary for the horn-minded people. All midbass horn are different a...

[quote user="RF at Ona"] Congratulations on the construction and installation of your horns. May your pleasure at the results reward your effort and expense. I find their installed appearance even more geometrically striking than anticipated and I su...
