    Omni-directional Horn-speaker 2426H

    Hello,

    I need advice or (mathematical) helps.

    I want to build a omni directional horn. I want to use the JBL 2426H driver in combination with JBL 2118H. Crossover frequence about 800hz
    How can i calculate the horn for the 2426H and the 2118H?
    Do you think its an good idea?

    Kind regards Matthias

    So when decide the type of the horn You want to make, You an recalculate step by step (say every 2mm apart) the sound wave front surface area depending of the distance from the horn throat, and to start wood milling . I wish You great success in Your work.

    Hi Matthais,

    I too have been thinking about applying the 2425/2426 to the Bella Luna Diamante design. Have you had a chance to hear one? I've not found one locally to listen to here in California.

    I own 2425/E110/E155 that are available for a DIY project and I am considering this design too (though the E155 needs a 3.1 cu ft cabinet). These drivers are from a pair of 4699b's I have: http://www.audioheritage.org/vbullet...-with-my-4699b

    Do post any progress you make!
