Lightweight construction
49 mm (2 in) throat entry
The JBL 2382A Bi-Radial™ horn¹ 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 in
line.
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 the
25 mm (1 in) throat 2425 driver.
