Large Format Optimized
Aperture Bi-Radial® Horn Family

Professional Series

Key Features:

P Optimized ApertureTM horn design
provides very low distortion at high
sound pressure levels.

> Large format horn family provides
uniform on and off axis frequency

response from 300 Hz to above
3 kHz.

D Controlled horizontal and vertical
pattern in 90° x 50°, 60° x 40°, and
40° x 30° coverage patterns.

F 76mm (3 in) throat entry.

JBL models 2392, 2393, and 2394 are
valuable additions to jBLs family of
Bi-RadialC horns, providing uniform
coverage control over the bandwidth
of 300 Hz to above 3 kHz, allowing
precise control of critical vocal range
energy. These large format horns
provide extremely low distortion at
typical peak sound pressure levels of
up to 145 dB-SPL at 1m (model 2394).

Optlmized Aperture -

The clear and uncolored sound
character of the 2390-Series horns is
accomplished by coupling the
compression driver phase plug to a
unique horn throat geometry, resulting
in the elusive combination of
extremely low throat distortion with
high air movement capability. These
horn designs were verified through the
use of advanced technology, including
finite element analysis, boundary
element analysis and extensive
computer modeling via proprietary jBL
horn design software.

Components and Accessories -

The 2390-Series of horns were designed to be used exclusively with the
2490H midrange compression driver. The diaphragm for this driver utilizes a
three-dimensional diamond pattern surround and a pure titanium diaphragm
for rigidity and freedom from breakup modes. With its 200 watt continuous
program rating and optimized phase plug design for low distortion, smooth
response and wide bandwidth, the 2490H is ideal for use in high level sound
pressure applications.

The 2510 Mounting Bracket is recommended for suspension of the
horn/driver combination. The 2510 sandwiches between the horn and driver
providing multiple pickup points, including a slot that allows front/back
alignment.

Optional Weather-Resistant versions are available, providing a 3-layer
weather resistant grill and sealed chamber for the driver.
