  Your drawings look nice, Angelo. My only suggestion would be to explore designs that exploit the benefits of full horn loading.

  Emmanuel Berlant had a patent that was in a similar vein. Not sure whether this is "Bert" Berlant of Concertone fame or perhaps his son.

    hi Steve

    thanks for your reply. A basshorn unfortunately has no reasonable size, that's why it is not very commercial. At this moment, this is my first criteria. There is also timedelay problems....

  Duevel makes several horn-based omnis. Wolcott uses two hemispheres to form a 360 degree horn for a high output dome - which I think is quite ingenius.

  Looks to me like your drawing depicts a mixture of features that are going in opposite directions.

  Who or what is AudioVoice? Are you a manufacturer?

    hi Duke

    the dome 360degree tweeter is interesting indeed.
    I am just starting building my first speaker as a hobby. AudioVoice is the fantasy name of my creations. The idea is, yes, to sell one ore the other speaker, if there is demand out there.

      Thanks for the clarification.

      As I'm sure you appreciate, big speakers done well will outperform small speakers - the problem is big speakers are unwelcome in most rooms. Now if they're big and look great, they have a much better chance. I'd say you are way, way ahead of most manufacturers in that regard. My compliments on your having combined elegance with massiveness. Do you have an artistic or industrial design background?

      In my experience, a large stand-mount speaker is tough to sell. I think the perception is, a speaker that takes up that much space might as well go all the way to the floor. I have manufactured two large stand-mount speakers and both have been slow in the marketplace. One of them I simply stuck in a floorstanding cabinet, and it has done much better in that format. So, if I were going to suggest a model for you to focus on first, it would be the "Sonata" - in my opinion it's the one most likely to appeal from an aesthetics and practicality standpoint.

      Now there is a certain appeal to the innovative "Bariton", but that one would be more of an uphill battle because you will be challenging more preconceived notions (mine included). As a dealer, the "Sonata" is the one I'd be most interested in selling (hypothetically). And as a manufacturer, the "Sonata" is the one I'd least want to compete against (fortunately I think it will be well above the price range of my offerings).

      At some point "hobbyist with intent to sell" becomes "manufacturer" - just be aware that the day is probably not far off when it would be appropriate for you to register as a manufacturer.

      Just for the record, I'm more of a dealer than a manufacturer (though I do a little of both), so that's how I'm registered.

      Best of luck with your venture!

        Hi Duke

        thank's for your post. i am industrial designer. I have the same perception, small speakers sell easier. Specially China, Hong Kong, and Japan, there is a big market for high-end speakers with nice design, but people there do not have big houses ore apartments, so their only choice is to buy smaller models. That's why i designed the Soprano. U are right, when the Sonata is built, and my homepage is up, and there are orders, i will have to open here a company for export and import ( i live in brazil )
