23T
Ultra-Compact
Indoor/Outdoor
Background/Foreground Speaker
Key Features:
Isolation transformer for
70.7V/100V distributed-line sound
systems.
Components: 3½” Polypropylene
coated woofer, ½” Titanium coated
horn loaded tweeter.
Built-in InvisiBall®mounting
hardware
Weather resistant enclosure and
transducers
Readily paintable to match decor
90° x 90° high frequency horn
Overload Protection Circuitry
The Control®23T 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 impact. The Control 23T can
be used in either 70.7V or 100V
distributed-line sound systems. The
single power tap is 5W at 70.7V and
10W at 100V.
The unique InvisiBall mounting
hardware is included in each system
and makes short work of permanent
installation. In addition to rapid
installation, the InvisiBall mounting
method adds the benefit of vertical
rotation of up to 37° and horizontal
rotation of up to 44°. Because
InvisiBall adjustments are made
through a hidden access behind the
logo badge, the grill never needs to
be removed, while providing a high
degree of theft deterence.
The Control®23T 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 23T) and white (Control 23T-WH).

Continuous program power is a conservative expression of the system’s ability to handle normal speech and music
program material and is defined as 3dB above the Continuous Pink Noise Rating (IEC-shaped pink noise with a 6dB
crest factor, for 100 hours continuously).
JBL continually engages in research related to product improvement. Changes introduced into existing products without
notice are an expression of that philosophy.

Architectural Specifications:
The loudspeaker shall consist of a 90mm (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: Usable frequency response shall extend from 100 Hz to 21 kHz
(10 dB below rated sensitivity, in half-space, with no external
equalization). The loudspeaker shall be equipped with a transformer for
use in either 70.7 or 100V distributed-line sound systems. The tap shall
be nominally 5W @ 70.7V and 10W @ 100V. The frequency dividing
network shall have a crossover frequency of 3.5 kHz. Rated power
capacity of the coimponents and network shall be at least 50 watts
continuous program power, defined as 3dB above a test signal of filtered
random noise conforming to international standard IEC268-5 (shaped
pink noise with a peak-to-average ratio of 6dB), for 100 continuous
hours duration.
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
horn-loaded to more evenly cover a nominal 90° horizontal by 90°
vertical area.
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 or structural integrity: salt spray (method 509.3),
temperature -19°C to 49°C (method 501.3 and 502.3), 95% humidity
(method 507.3) and ultra-violet (method 505.3). The system shall have a
IEC 529 splashproof rating of IP-X4.
For theft deterrence, the installation access area shall be hidden
behind a snap-out cover, and the access area shall be on the front of the
loudspeaker for ease of installation and adjustment. The loudspeaker
shall be rotatable over a minimum of ±35° in all directions via a
ball-type mounting system. The ball mechanism shall be internal to the
cabinet to allow low-profile mounting and better stability via a short
moment arm. The logo shall be rotatable for proper orientation when
the loudspeaker is mounted horizontally or vertically.
The external wiring connectors shall be spring loaded and gold
plated, and shall accept bare wire, single or dual banana-type
connectors with 19 mm (3/4 in) spacing. Overall cabinet dimensions
shall be no greater than 193 mm (7.6 in) high by 140 mm (5.5 in) wide
by 111 mm (4.4 in) deep and shall weigh no more than 1.8 kg (4 lbs).
The finish shall be a paintable lighly textured black.
The system shall be the JBL Model Control 23T with included
InvisiballTMmounting system.
