Applications:
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
broadband basis.
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
(½ in) medium density fiberboard to provide the performance of a top quality wood
loudspeaker cabinet in a metal backbox
form factor.
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
lines.
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.
