Applications:
The
Control
31
utilizes high-power components, computer optimized
horn,
and
a complex network
to
achieve smooth, powerful high-fidelity
performance, extended bandwidth, and well-controlled defined coverage
from a compact loudspeaker.
The 250
mm
(10 inch) low-frequency driver features a woven fiberglass cone
for a high degree
of
weather capability and pure butyl rubber surround for
clean sound quality, a high-temperature fiberglass voice coil former for high
sensitivit
y,
high
output
capability and stable performance under long-term
high power working conditions. The optimized cone geometry provides
for smooth frequency response and
good
off-axis performance. A linear
suspension spider provides l
ow
distortion, while
FEA
-optimized
motor
construction produces minimum harmonic distortion.
An
aluminum
coupler ring outside the pole post further reduces distortion and further
increases the sensitivit
y.
The high-
output
high frequency compression driver features a unique
patented design, high temperature polymer diaphragm, and fluid-cooling
for high
output
levels with low distortion.
The high-frequency waveguide was designed using JBL's advanced
lmageControl'" process for accurate, low-distortion control,
wit
h smooth
frequency response and excell
ent
sound character
throughout
the frequency
band, over the entire listening area. It's
11
oo x
11
oo symmetrical coverage,
provides the same coverage regardless whether the cabinet
is
installed in
vertical
or
horizontal orientation.
The field-proven
top
-quality line distribution transformer, designed for
minimal insertion loss and reduced saturation, allows for use
on
either
70V
or I
OOV
distributed speaker lines. In the Thru setting, the 8
ohm
impedance
allo
ws
for the use
of
up
to
two speakers
on
a 4-ohm capable amplifier
channel.
The included lnvisiBall mounting
method
is
simple
to
install, aims easily
and provides a high degree
of
theft deterrence. InvisiBall allows horizontal
rotation
of
up
to
41
o off-axis and vertical rotation
of
up to 36° (
horn
end
inward)
or
23° (woofer
end
inward). Attachment points for the optional
MTC-30UB
(&
"-WH"
for white) U-bracket allows for compact
installation
and
is
particularly useful for low-profile applications.
Weather resistance has been maximized. The low-frequency driver features
a woven fiberglass cone, a pure butyl rubber surround, and the basket
is
rear loaded into the baffie
to
minimize exposure. The high
-f
requency
compression driver has a highly weather capable
pol
ymer diaphragm. The
grille is thermoset composite coated and stands up well
to
UV
as
well
as
humidity. The grille
is
backed with
our
WeatherMax- multi-layer foam
and tight-weave screening
to
help prevent incursion
of
water. Nicke
l/z
inc
rust-resistant terminals ensure a secure input connection.
An
MTC
-
PC2
sealed-entrance cover
is
included
to
further protect the speaker's terminals.
The white-version cabinets are
painted
with a
UV
-resistant finish
to
resist
ye
ll
owing due to
UV
exposure.
Available in black
or
white (
-W
H ),
th
e cabinet will accept a variety
of
paints
to
match any decor.
