BI~RADIAL HORN

FEATURES: The jBL 2382A BiiRadialTM horn is designed for

flush cabinet mounting or compact cluster applicai
tions. The 2382A has a nominal 120° horizontal x 40°
Vertical pattern. The horn provides uniform onr and

conventional horn designs. Additionally, the predicts
able performance of the 2382A greatly simplifies
cluster design The need for horn overlapping is
minimized, and lobing and comb filter effects are
virtually eliminated.

Computersaided design techniques were used to
derive the horn contours in both horizontal and vertis
cal planest Using sidewall contours based on a poly
nomial power series equation, the horn design yields
smooth response, low distortion, and consistent cove
erage over defined solid angles. The design avoids

SPECIFICATIONS:

the performance disadvantages of horns that feature
sharp flare transitions and flat sidewallst To ensure
light weight, superior strength, and freedom from ress
onances, 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.
