Details
The JBL 2385A Bi-Radial horn is designed for flush cabinet mounting or compact cluster applications. The 2385A has a nominal 60� 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 constant directivity above 2 kHz. The horn? s small 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 vertical pattern control be required below 2 kHz, two or more horns may be stacked vertically to restore full Bi-Radial? performance. The exceptionally consistent horizontal dispersion eliminates the midrange narrowing and high frequency beaming problems typically associated with conventional horn designs. Additionally, the highly predictable performance of the 2385A 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 the horizontal and vertical planes. Utilizing sidewall contours based on a polynomial power series formula, the horn design yields smooth response, low distortion, and even coverage. This design avoids the performance disadvantage of horns that feature sharp flare transitions and flat sidewalls. The Bi-Radial?compound flare configuration provides constant coverage over defined, solid angles. To ensure light weight, superior strength, and freedom from resonances, the horn bell is constructed of molded structural foam. The 2385A will accept the 49 mm (2 in) diameter throat 2446, 2450, or 2485 compression driver. With the addition of the 2327 adapter, the horn will also accept the 25 mm (1 in) throat 2426 driver.
