Horn Family

Key Features

c Optimized ApertureTMhorn design

provides very low distortion at high
sound pressure levels

c Mid-format horn family provides

uniform on and off axis frequency
response from 630 Hz to 20 kHz

c Controlled horizontal dispersion in

90° x 50°, 60° x 40°, and 40° x 30°
coverage patterns

c 38 mm (1.5 in) throat entry

JBL models 2352, 2353, and 2354 are
medium format elements of JBL’s
preeminent family of Bi-Radial®horns,
providing uniform coverage control
over the bandwidth of 630 Hz to
beyond 18 kHz, allowing precise
control of critical vocal range energy.
These medium format horns provide
extremely low distortion at typical
peak sound pressure levels of 139 dB­SPL at 1m.

Optimized Aperture

The clear and uncolored sound
character of the 2350 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.

Professional Series

Components and Accessories

The 2350 Series of horns were designed to be used exclusively with either
the 2447 or 2451 compression driver. The 100 mm (4 in) 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
150 watt continuous program rating above 1 kHz and optimized phase plug
design for low distortion, smooth response and wide bandwidth, it matches
with the 2350 Series horns for high sound pressure level applications.

The 2510 mounting bracket is recommended for suspension of the
horn/driver combination. The 2510 installs between the horn flange and
driver providing multiple pickup points.
