2382A Flat-Front Bi-Radial Horn

    Manufacturer Description

    The JBL 2382A Bi-Radial horn is designed for flush cabinet mounting or compact cluster applications. The 2382A has a nominal 120° horizontal x 40°vertical pattern. The horn provides uniform on- and off-axis frequency response from 500 Hz to beyond 16 kHz in the horizontal plane and 2 kHz to 16 kHz in the vertical plane, with uniform directivity above 2 kHz. The horn's vertical mouth dimension (just slightly larger than the compression driver used to drive the horn) allows very compact single and multiple horn/driver systems to be put together. Should tighter vertical pattern control be required below 2 kHz, two or more horns may be stacked vertically inline.

    The exceptionally consistent horizontal dispersion eliminates the midrange narrowing and high frequency beaming problems typically associated with conventional horn designs. Additionally, the predictable performance of the 2382A greatly simplifies cluster design. The need for horn overlapping is minimized, and lobing and comb filter effects are virtually eliminated.

    Computer-aided design techniques were used to derive the horn contours in both horizontal and vertical planes. Using sidewall contours based on a polynomial power series equation, the horn design yields smooth response, low distortion, and consistent coverage over defined solid angles. The design avoids the performance disadvantages of horns that feature sharp flare transitions and flat sidewalls. To ensure light weight, superior strength, and freedom from resonances,the horn is made of molded structural foam.

    The 2382A will accept the 49 mm (2 in) throat 2441,2445, or 2485 compression driver. With the addition of the 2327 adapter, the horn will also accept the25 mm (1 in) throat 2425 driver.
