Two-Way Coaxial, Optimized
Aperture Bi-Radiali I-Iorn Family

Professional Series

Key Features:

> Two-way coaxial horn family
providing a high SPL, wide
response point source.

> Controlled horizontal and vertical
pattern in 90°x50°, 60°x50°, and
40°x30° formats.

> Uniform on and off-axis frequency
response from 300 Hz to 16 kHz.

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

> 2390-Series mid-frequency horn
and 2490H large format
compression driver with
76mm (3 in) exit.

> High-frequency horn and 2451H
large format compression driver
with 38mm (1.5 in) exit.

> Weather-resistant version available.

The coupling of JBL's patented
Bi-Radiali, mid-frequency and
high-frequency horns into a colinear
loudspeaker has produced a
convenient package for supplying
high sound pressure levels over a six
octave bandwidth from a point
source.

Constant horizontal and vertical
coverage patterns over the bandwidth
of 300 Hz to 16 kHz allow precise
control of sound energy. Greater
intelligibility is more easily achieved
while reducing problems with lobing,
comb filtering and system
gain-before-feedback issues.

Both the high-frequency and
mid-frequency horns use Optimized
Aperture technology that results in
improved driver-te-horn coupling and
lower distortion levels.

Components:

The JBL Coaxial Bi-Radial horns are the result of the finest horn and
compression driver technolo . The coaxial horn family offers the system
designer the best possible so ution for covering the bandwidth from 300 Hz
to 20 kHz at maximum continuous sound pressure levels with the highest
practical efficiency.

Both the mid-frequency and high-frequency horns were developed using
advanced computer modeling, including JBLs proprietary horn design
software, finite element analysis and boundary element analysis. The
application of this advanced technology helped create the Optimized
Aperture horns used in this design and greatly reduces throat distortion,
while effectively extending usable high frequency response.

The compression drivers utilized in the coaxial horn family are the 2490H
at mid-frequencies and the 2451H at high-frequencies. Betti drivers utilize a
three-dimensional diamond attern surround, and a pure titanium
diaphragm for stiffness and reedom from break-up modes.

The 2192, 2193 and 2194 horns are designed to be bi-amplified using the
JBL DSCZSO controller, which provides crossover, signal alignment, EQ, and
limiting functions to obtain optimum performance with the coaxials.

Also available are the 2192-WR, 2193-WR and 2194-WR coaxials with the
weather-resistance option, The weather-resistant version includes a rugged
3 layer rain-resistant grille and a sealed chamber for the mid-frequency
driver. Non-corrosive, stainless steel suspension points are also included.
