JBL Control 322C High-Power 12” Coax Ceiling Loudpeaker with Medium Format Compression Driver
Consistent 90° broadband pattern control.
• Kevlar-reinforced 300 mm (12 in)
woofer with 75 mm (3 inch) voice-coil
• Medium-format compression driver.
Extraordinary clarity for speech and
vocals with extended frequency response
Power handling of 400 Watts with high
sensitivity provides high SPL capability.
Advanced high-slope crossover network
for constant coverage and smooth, natural
Clean, contemporary grille and optional
Control 322C and Control 322CT deliver
exceptional next-generation performance in
a coaxial point source design ceiling loudspeaker.
The low frequency cone performs
as a true 12 inch (300 mm) diameter waveguide
for the high frequencies. A unique
metal throat transitions seemlessly to the
horn to eliminate high frequency beaming
which is common among this category of
speaker. The result is a coaxial speaker
with extremely consistent 90° coverage on a
Component features include a Kevlarreinforced
low frequency cone for reliability,
well-damped surround for smooth frequency
response, high temperature 75 mm (3 in)
voicecoil and a reduced distortion design
through saturated-gap magnet geometry.
The high efficiency medium-format high
compression driver features a radial slot
phase plug for a smooth, extended high frequency
response, along with a neodymium
magnet for low installation weight.
The Control 322C and Control 322CT are
easy to install. The innovative EZRail™ feature
built into the metal baffle temporarily
holds one side of the speaker baffle in
place until the installer can affix the baffle
to the backcan with screws. The removable
multi-pin locking connector, with
secure screw-down terminals, allows for
pre-wiring the input wires for easy clip-on
convenience during installation.
The clean, contemporary look of the
optional MTC-300SG12 square grille is
designed to suit high-end venues, offering a
simple, elegant appearance that fits into a
wide variety of décors.
The optional, best-in-class, MTC-300BB12
three cubic foot backcan is made of extrathick
16 gauge steel and lined with 12 mm
(˝ in) medium density fiberboard to provide
the performance of a top quality wood
loudspeaker cabinet in a metal backbox
The transformer version Control 322CT
comes with a pre-attached top quality, low
saturation 100 Watt multi-tap transformer for
use on 70V or 100V distributed speaker
To ensure long life and reliability, Control
322C/CT passes JBL’s 100-hour torture
power test. Nobody in the industry has
more deminading reliability standards.
