Applications:
Control 312CS is an excellent
addition to JBL Control 321, 322 and
328 loudspeaker systems, or any fullrange loudspeaker system that requires
extended bass response.
The 300 mm (12 inch) driver features
a Kevlar-reinforced low frequency cone
for reliability, well-damped surround,
extended excursion capability, high
temperature 75 mm (3 in) voicecoil and
reduced distortion through saturatedgap magnet geometry.
The Control 312CS is 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 extra-thick 16 gauge steel
and lined with 12 mm (½ in) medium
density fiberboard. This provides the
performance of a top quality wood
loudspeaker cabinet in a metal backbox
form factor.
Control 312CS is intended for
systems utilizing an external active
subwoofer crossover and separate
amplifier channel for the subwoofer
loudspeaker(s).
To ensure long life and reliability,
Control 312CS passes JBL’s 100-hour
torture power test. Nobody in the
industry has more demanding reliability
standards.
