Hi to Everyone
Some manufacturers have used horns with conventional drivers with great results from what i understand and listened in some occasions
I refer to Avantgarde and Acapella in particular
Fwiu they have used off the shelf drivers like Audax and Dynaudio and exalted their performance using a properly designed and built horns
I wonder if anyone has tried for instance an off the shelf horn with a dome tweeter and what the result
Thanks a lot
Gino

Hi yes I should have said that i am more interested in horn loaded mid and high drivers like small cones and domes
Bass horns i have no chance to do them
For instance what about using an off the shelf 2" throat horn with a 2" dome?

High frequency response is typically limited in these configurations. The problem is the energy coming off the diaphragm doesn’t add coherently when dimensions get long with respect to a wavelength. There are differences in path length (to the mouth) between one part of the diaphragm and another. That’s why compression drivers have phase plugs - to improve this situation. I suppose you could design a phase plug but that’s not something one just goes and does in an afternoon. The result of course, would be a compression driver. And then the driver itself may have too much moving mass to be effective at the frequencies you want - little no no gain from the horn due to acoustic mismatch. To do this with a midrange is a little easier - because reaching a kHz or two is easier in all respects.
Hi thank you for the very kind and valuable advice
I understand that is a weird idea very difficult to put in practice
No more doubts Horns are intended for compression drivers
I will study those I would like to build a 2 ways and i like horn tweeters a lot
Like Klipsch does

Maybe this thread would be useful: https://www.diyaudio.com/community/threads/2-madness-hornloading-the-tb-w2-803sm.205146/
Hi thank you for the very kind and valuable link
This is exactly what I had in mind for a 2 ways project above a PA 15" woofer
I will read the thread with great attention
Kindest regards Gino

There were several sucessfully completed projects.
Unity horn with 2" driver. Dropbox link has expired, but you could ask Christian for reupload if you intend to print his horn:

Unity horn with 2.5" driver, spherical enclosure:

Just some measurements of the 2" driver on "90x40" (quotes for supposedly non-constant directivity) horn:

Hi thank very much for for your very valuable advice
My idea was to try possibly a 2" horn off the shelf with a wide band driver to cover the range from 1k up Below a PA woofer would be just fine in order to have a good efficiency speaker
I like speakers with narrow dispersion Once seated in the sweet spot every thing will fall in focus nicely
I will study the thread you mentioned carefully

The highly regarded (by some anyhow) JBL SVA series used the audax 34mm dome in a horn with what must have been some sort of success?
I have a pair of TWO34XO and some SEOS-8 waveguides with intentions to mate them sooner or later…….problem is my stack of intentions is bigger than my stack of completions! 😎

Hi i know very well those speakers 5 years ago was about to buy them for a nice price
But I was abroad and scared at the idea of moving back home with too much luggage
I missed a pair of ProAc EBS for 800 euro The had a ATC mid between Scanspeak drivers
Crossover frequency: 1.2kHz from sva 2100 specs
Some PA 15" could reach than point i guess Just one would be enough

I have to check if they are available in Europe
Great opportunities you have in US
Lucky you

Very interesting indeed

A diaphragm larger than the throat will raise efficiency and damp resonance. So a 2" dome to a 2" throat is not taking full advantage.
There are two roots of horn design. One is a telephone receiver (earpiece) with a long horn for output and throw; the other is a 8" cone in a short-horn for a little efficiency and a little throw (these grew to 15" cones with 8"-10" throat).

Hi thank you very much but i Don't understand
Let's say that i have some 2" drivers available, either domes or cones
Which horn size do i have to use?
I asked about this weird concept because there are at least two brands that have built their success on this approach Avantgarde and Acapella
Acapella use i think a 2 inches dome with a horn
Avantgarde both a cone midrange from Audax and a dome
They sell for thousands of dollars and people like their sound a lot
I prefer Acapella It's midrange is just sublime Astonishing
