transformer for 70V or 100V distributed lines, with 8
thru bypass.
Extended bandwidth, extremely smooth frequency response
Highly outdoor-capable design with included
WeatherMax™ multi-layer grille and optional marine-kit
grille for salt-air environments.
110° x 110° symmetrical coverage.
Includes InvisiBall® mounting hardware plus ten 6 mm
attachment points for suspension and optional U-bracket.
Included sealed input panel cover and screw-down input
terminals for secure connection.
Applications:
e Control 31 utilizes high-power components, computer optimized
horn, and a complex network to achieve smooth, powerful high-delity
performance, extended bandwidth, and well-controlled dened coverage
from a compact loudspeaker.
e 250 mm (10 inch) low-frequency driver features a woven berglass cone
for a high degree of weather capability and pure butyl rubber surround for
clean sound quality, a high-temperature berglass voice coil former for high
sensitivity, high output capability and stable performance under long-term
high power working conditions. e optimized cone geometry provides
for smooth frequency response and good o-axis performance. A linear
suspension spider provides low 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 sensitivity.
e high-output high frequency compression driver features a unique
patented design, high temperature polymer diaphragm, and uid-cooling
for high output levels with low distortion.
e high-frequency waveguide was designed using JBL’s advanced
ImageControl™ process for accurate, low-distortion control, with smooth
frequency response and excellent sound character throughout the frequency
band, over the entire listening area. It’s 110° x 110° symmetrical coverage,
provides the same coverage regardless whether the cabinet is installed in
vertical or horizontal orientation.
e eld-proven top-quality line distribution transformer, designed for
minimal insertion loss and reduced saturation, allows for use on either 70V
or 100V distributed speaker lines. In the ru setting, the 8 ohm impedance
allows for the use of up to two speakers on a 4-ohm capable amplier
channel.
e included InvisiBall mounting method is simple to install, aims easily
and provides a high degree of the deterrence. InvisiBall allows horizontal
rotation of up to 41° o-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-prole applications.
Weather resistance has been maximized. e low-frequency driver features
a woven berglass cone, a pure butyl rubber surround, and the basket
is rear loaded into the bae to minimize exposure. e high-frequency
compression driver has a highly weather capable polymer diaphragm. e
grille is thermoset composite coated and stands up well to UV as well as
humidity. e grille is backed with our WeatherMax™ multi-layer foam
and tight-weave screening to help prevent incursion of water. Nickel/zinc
rust-resistant terminals ensure a secure input connection. An MTC-PC2
sealed-entrance cover is included to further protect the speaker’s terminals.
e white-version cabinets are painted with a UV-resistant nish to resist
yellowing due to UV exposure.
Available in black or white (-WH), the cabinet will accept a variety of paints
to match any décor.
