Look at this _>
hes making fun of the horn! Hes got better stuff up his sleeve! You are assuming that I abandoned the idea (of fabricating one of their horns)! I didn't! Stop it right now lol!
I agree with you (about Docalis horns being better) thats why you confuse me.
He got exactly those hors that fulfilled his goals. Then he changed his goals. It is simply not possible to make a horn that loads such low with wide dispersion with the dimensions he requested.
But to be honest the Jericho even some longer would represent a very good fog horn at the coast

Well now that we both agree that Docali makes the best horns...
How do you feel about my decision to move the xover higher, and also crossing closer to the fundamental? Crossing at 400hz with a probably 320hz horn...
I say that because a horn of that tuning is what I want to fabricate....
Docali and Don will you pleeeeease?.......

I designed a system around being able to play 115db continuous at xmax or better with one channel....not considering that 115db music is not like a 115db sweep or test tone....so I just realized, a system that can play 115db sweeps and test tones (with one channel) is going to be incredibly loud if you just left the volume knob and hit play on your music, right after running such a test tone.....with 2 channels what happens then?...how'd you guys let me build this?
All I can think about now is what two of these subs sound like in my basement and how incredibly low my excursion (at all channels) is going to be at normal human, listening volumes (70-75db)

My horns are totally unimportant as we have learned here that they are bad design like jmlc horns are bad design. So, absolutely no need to heat up.
I tried to follow your latest posts. Please excuse me but I do not understand what are your goals. I have provided my latest calculator on my homepage to create your own horn if you still like but I cannot spend again this time again for you. Sorry. Once I provided a design to you you requested the next. It looked like a never ending path. Why not using these tuned OSWGs? As you are looking always for latest and greatest it would be maybe a more satifying way for you?

That's false. I can make an OSWG load to 300 Hz, you just wouldn't like it.
You are looking for nirvana - that "ultimate" design that doesn't exist because it can't be built within your constraints. Take some advice from the experts here and maybe you will get "close enough". Ignoring them, will lead you "down the rabbit hole".
Ditto that, but we have all been through this here before. It just doesn't seem to make an impression.
camplo, what you have added as hidden constraint to the title of your thread is wide dispersion.
There are only a few designs out that come close to all this. The fin horns TH4001, Yuichi, Yamamoto 280 and big multicell horns.
Your elliptical tractrix will not even come close and it is no wonder for me that many are surprised or disappointed after more than 600 pages.

One thing I am glad for is that you are building something and therefore whatever the outcome the entire thread did not come to nothing, it stands on it's own as a massive volume of useful information in any case.
It would make sense to invest some time in learning to use it or docali's calculators rather than hoping for someone else to again devote their time and effort which is substantial. Even though it may be easy for them it takes time which most of us don't have enough of.
I have to agree about the large pictures spoiling the content of the post by making it hard to read. I have ignored quite a few posts for just that reason. I was about to post before that at least you don't use different colours or fonts, then you did. Now I am lmao
Because you wanted it and having too much is better than not enough?
I can understand that some of the previous posts could have been taken as criticizing your work but they are surely excellent designs. They aim for a different result which not everyone wants or thinks is right. The effort and smarts required to make them should never be forgotten.
With the latest version of ATH the type of curve can be changed quite easily to be more like the spherical or jmlc or anywhere in between and even though the throat is OS you can limit that to a small percentage and have most of the curve be a Euler spiral by changing the rollback if that is desired.

Of course you can if the driver is happy doing it and you don't expect the SPL to be maximised.
Here is an example, not necessarily the best but it was on my desktop.
The waveguide is down 5dB at 400Hz from where is is through the majority of the range and it keeps letting go gracefully below that. This one is not small because I didn't want it to be narrow but it could have been much less wide if narrowing the pattern was acceptable.
This is all waveguide because there is no lumped element model of the CD being used. If you looked at the radiation impedance you might say no because it's virtually zero, but the polar and the SPL produced say yes

- OMG is it really that bad guys? It must be the netcode cause on my computer it will do that sometimes and I hit reload and all the pictures are how they should be. Even your picture above just did it, first the page loaded without a thumbnail, full size photo, then I hit reload and it shrunk your picture to thumbnail size...
(mental note....make smaller pictures lol)

Yes reloading works if the picture is under 1200 pixels wide, anymore and it doesn't work that well.
A simple solution is just to leave it as an attachment and not put it in line with the text. Then the text is readable and the thumnail below can be clicked on to make the picture whatever size it should be.
Resizing the pictures to 1084 wide is usually good because then it can't go bigger than the screen when enlarged.
Have a read of some of Patrick Bateman's threads and you have to scroll from left to right and back again to read what was written because of the huge pictures. If you want people to listen don't make hard to hear
I've done the same thing myself too.

Despite being vile diffraction horns, these sound pretty good, especially considering the improvised setup and the fact that they play from 320Hz (with the DCX464).
ok, what I always missed here in this thread was the proof of an oswg that fulfill camplos req. loadind down to 200Hz and his size restrictions. Should be easy to show us here with simulations and observation fields over the entire range.
The designs I showed will work for sure and the dispersion will be sufficient for 1 or 2 listening persons.
And to make it more challenging for you... you will not be successful with a pure os throat. An exponential throat is needed for this and this is known for more than 50 years.
