The Control 23 is the most compact
of JBL Professional’s Control
Contractor Series indoor/outdoor
loudspeakers making it a perfect
choice for patios, foyers, retail or
other applications where foreground/
background music and paging
are required, with minimum aesthetic
The unique and global patent
pending InvisiBall ® mounting hardware
is included in each system and
makes short work of permanent
installation. The InvisiBall mounting
method adds the benefit of vertical
rotation of up to 37° off-axis and horizontal
rotation of up to 44° off-axis.
Because InvisiBall adjustments are
made through a hidden access
behind the logo badge, the grill
never needs to be removed and there
exists a high degree of theft deterence
The Control® 23 readily accepts a
variety of paints and finishes to
match any decor.
Weather resistance is maximized by
coating the woofer cone in
polypropylene and terminating its circumference
in JBL’s WeatherEdge™, a
seamless, rubberized extension of the
woofer surround that provides added
protection to critical transducer elements.
The polycarbonate tweeter
diaphragm is reinforced with a thin
film of titanium for added rigidity and
endurance against sun, salt and moisture.
Zinc plated grilles resist rusting
in the harshest conditions.
Available in black (Control 23) and
white (Control 23-WH).
The loudspeaker shall consist of a 90 mm (3-1/2 in) low frequency
transducer, 13 mm (1/2 in) high frequency transducer, and frequency
dividing network installed in a ported enclosure. The low frequency
voice coil shall be 19 mm (3/4 in) in diameter.
Performance specifications of a typical production unit shall be as follows:
Measured sensitivity (SPL at 1 m [3.3ft] with 2.83V input, averaged
from 500 Hz to 1.5 kHz) shall be at least 86 dB-SPL. Usable frequency
response shall extend from 85 Hz to 22 kHz (10 dB below rated sensitivity,
in half-space, with no external equalization). Nominal impedance
shall be 8 ohms. The frequency dividing network shall have a crossover
frequency of 3.5 kHz. Rated power capacity shall be at least 50 watts
continuous program power, defined as 3 dB above a test signal of filtered
random noise conforming to international standard IEC268-5
(shaped pink noise with a peak-to-average ratio of 6 dB), for 100 continuous
The system shall be protected against damage from occassional overpowering
via full range series lamps that limits the power to the network
and transducers. The high frequency transducer shall be hornloaded
to more evenly cover a nominal 90° horizontal by 90° vertical
The enclosure shall be constructed of high-impact polystyrene for protection
against the elements in outdoor applications, and for paintability.
The grille shall be completely zinc-coated for resistance against rusting,
shall be bake-painted black, and shall be secured via screws to keep it
in place when facing downward.
The low frequency transducer shall have a polypropelene cone and a
butyl rubber surround which shall extend seamlessly over the edge of
the speaker frame for protection against the elements. The high frequency
transducer shall be constructed of polycarbonate, reinforced with a
titanium film for additional weather resistance. The system shall withstand
Mil Spec 810 testing with specified time durations for exposure to
the following environments with no effect on its acoustical performance
