    A good overview about horns you can find here:
    http://www.peavey.com/Media/pdfs/qwp1.pdf

    Although it's not JBL specific (Pavey) the differences between the following - and other - horns are explained
    - conical horns
    - exponential horns
    - radial horns (Smith-horn)
    - constant directivity horns (EV)
    - Mantaray horns (Altec)
    - Bi-Radial-Horns (JBL).

    In the following thread you can found links to even more profound literatur:
    http://audioheritage.org/vbulletin/s...roat+waveguide

    @german readers:
    There exists a german translation of the book "Winston E. Kock: Refraction Sound Waves",
    easy to understand, lots of pictures

    Horn Info

    I tried the link (the first one) because I thought it sounded interesting, but the Peavey site says the page no longer exists.

    Specifically, although I'm basically familiar with the various horn types you listed, I was curious as to the reason for the "Smith Horn" designation for the bi-radial type. Who was this Smith?

    I beg your pardon, I thought I had tested the link:
    www.peavey.com/media/pdf/aa/qwp1.pdf

    On page 3 of this paper you see straight sidewalls with a fixed angle. When the upper and lower sides are curved you will get a radial horn. If the upper and lower sides are in parallel and the flare is controlled by septas (?) then it will be a smith horn.

    At http://audioheritage.org/vbulletin/s...ght=Smith+horn
    you will see a beautiful original Smith horn. There is a paper by Smith and Selsted as well.
    At http://audioheritage.org/vbulletin/s...ght=Smith+horn
    there is an excellent home made horn. A further link shows a constructing drawing and pictures which show how to construct. (very inspiring!)

    There is one horn called parabolic. This concept is fairly new.


    Attempts in the past were unsucesfull .With todays technology it is possible to attain greater distances and DB,without compromising quality.
