Horn-based speaker projects

[Vineethkumar01]

Hi All,
Due to my newly found love for horn-based speaker projects, I found some links which may be good. Sharing for others interested.
This site has many horn-based speaker projects:

Joseph Crowe Audio Products

Joseph Crowe is a business offering design and built-to-order components and speakers. We specialize in Horn Speakers and Bass Cabinets.

josephcrowe.com

He has subjective and objective assessments for most of his projects..
Look-of-the-speaker-wise, I like some of his projects like the nighthawks and its subsequent versions.
As of now, I am not qualified enough to comment/judge about its sound quality-related aspects..

For anyone interested in building your own horn-based projects, please check out:

Acoustic Horn Design - The Practical Way

It was suggested to me to start a thread regarding the actual practical builds of horns and waveguides, mainly designed with the Ath. So here it is, for everyone to share their own way of converting their design into something real and listenable. Show off! :) So far the tool can generate: -...

Many designs are even available for free for 3D printing, CNCing.

Good thread! Will watch.

Have you learnt Hornresp yet?

No. not yet.
This is all i know about hornresp yet (using it for transmission line design):

Well when you've mastered it please let me know, I gave up DIY so I never really got into it. I'd be interested to see what horns you come up with once your familiar with the software.

Did you consider learning Akabak? I did not

Sure.. Akabak is another future personal goal for me.. I am very interested after seeing the ABEC results about cabinet impact on driver radiation that i got done with others help in my current project..
Only issue for me in doing all this is lack of time. My job buries me in a lot of boring work. Hopefully i will find time, learn it and once done, I will surely let you know..

Sharing Scott's video on bass horns... again design tips using hornresp.
I think Scott works in some Pro audio company and he has a lot of big speakers/horns at home..
I like Scott's videos and papers in general. He writes easy to read and understand papers on all things related to speaker design.
He has a facebook page called DIYRM.
Here is one relevant to this subject of horns:

Sharing a link to his other works here:

Wow!
Are we talking about objectivity here?
With the aid of design software?
And the discussion is yet civil with no hate posts so far?
Double wow!
Congratulations, all!

Keith, I am not opposed to understanding objectivity. I am opposed to using it as the final measure of a product. Just in case you meant me, all in good faith

A must read for horn enthusiasts including myself for learning some basics of horn theory: https://www.grc.com/acoustics/an-introduction-to-horn-theory.pdf (current golden reference about the theory: https://www.parts-express.com/High-Quality-Horn-Loudspeaker-Systems-500-032)

Horns !! I run ALTEC VOTT A7-8s in my apartment. ' Truly enjoy them.

Kindly please, view the web pages of Inlowsound.com. John Inlow is a very nice person, a DIY horn enthusiast, a man with wonderful grace, and his web site is fun to view, and in many ways, compelling to experience.
