Control®26C/CT Background/ Foreground Ceiling Speakers
Coaxially mounted 165 mm (6.5 in) woofer
with butyl rubber surround and 19 mm
(¾ in) titanium coated diffraction-loaded
High power, wide frequency response and
low distortion for high sound level
Wide coverage allows fewer speakers,
reducing the cost of the installed sound
system without sacrificing performance
JBLs exclusive SonicGuardTM overload
protection allows higher operational levels
and improved system reliability (26C only)
Packaged with grille, backcan and tile rails
for fast installation and easy dealer stocking
The Control 26C is a compact ceiling
speaker providing premium performance in
background, foreground music sound
systems. The Control 26C is perfectly suited
for a wide variety of applications from
casinos and hotels to upscale restaurants and
themed locations. High power handling, wide
frequency response and low distortion make
the Control 26C ideal for sound systems
requiring a higher fidelity sound from ceiling
loudspeakers. The premium performance
capability ensures excellent sound character,
providing pleasant, enveloping sound
throughout the listening area.
The Control 26Cs 16 ohm impedance
allows use of multiple speakers in parallel
without having to use a more expensive
constant voltage distributed system. The
optional Control 26CT version includes a
multitap transformer for 70V/100V systems.
JBLs exclusive SonicGuard overload
protection is a non-invasive loudspeaker
protection system that is inaudible to the
listener, ensuring reliability while providing
full fidelity sound. The computer-optimized
ported enclosure delivers warm, smooth bass
response. Low frequency output can be
further augmented with the addition of one
of the Control Contractor subwoofer models.
The 165 mm (6.5 in) woofer features a
polyurethane-coated cone and pure butylrubber
surround for long life, even in high
humidity environments. An aluminum voice
coil former provides extra cooling for greater
long-term power handling.
The coaxially mounted 19 mm (¾ in)
titanium coated tweeter provides crisp, clear
highs. Diffraction-loading of the tweeter
provides wide, even coverage of the listening
area. The extremely broad 110° coverage
pattern allows for fewer speakers to be used,
making for a simpler and less expensive installation.
Control® 26C/CT Background/Foreground Ceiling Speakers
Input connection is conveniently provided on a removable
locking connector (included), providing secure connection via
screwdown terminals and allowing a system to be prewired before
installing the speaker for fast snap-on convenience. Separate
connector terminals are available for the input and for the loopthrough
wires, making it easy to jumper the speaker signal to
additional speakers. The input terminal plate provides strain relief
for either bare wire, plenum cable or ½ inch conduit (12 mm I.D.).
The terminal box is securely enclosed to meet safety codes.
The speaker trim and grille are paintable to match any decor. A
paint shield is provided for covering the drivers while painting the
Installation of the Control 26C is quick and easy. The
loudspeaker is packaged complete with the backcan, grille, support
backing bracket and tile rails.
The entire installation can be accomplished without requiring
access above the ceiling. A template is provided for marking the
cutout. An innovative C-shaped support backing plate can be
installed from below through the cutout to reinforce the top of the
ceiling material. Tile bridge rails are included which can be
screwed onto the C-plate to extend support to the T-channel grid
in suspended ceiling installations. After the speaker is fitted through
the cutout, it is held securely in place via three mounting tabs
which tighten onto the C-plate, if used, or directly onto the ceiling
The Control 26C backcan is made of formed steel and the
speaker is suitable for use in air handling spaces, per U.L.-2043. An
attachment loop is provided on the backcan for cabling to the
building structure as a secondary support in seismic areas or where
required by code.
The model Control 26CT includes a 60W multitap transformer
for use in either 70.7V or 100V distributed-line systems. The
transformer effectively limits the power to the speaker, so
SonicGuard is not included in the Control 26CT. Taps are selected
with a rotary switch conveniently located on the front panel, but
protected under the grille, so that the speaker does not have to be
removed to adjust tap settings.
All JBL Control Contractor loudspeakers - both ceiling speakers
and surface-mount models - are designed with a similar sonic
signature, allowing for mixing and matching of the various models
within an application, providing a similar tonal character
throughout the entire listening area.

Control® 26C/CT Background/Foreground Ceiling Speakers
The loudspeaker shall be of in-ceiling design, consisting of a 165 mm (6.5 in) low frequency transducer, a coaxially-mounted 19 mm (¾ in) high frequency transducer, and
frequency dividing network installed in a ported enclosure. The low frequency voice coil shall be 25 mm (1 in) in diameter and the coil former shall be of aluminum for maximum heat dissipation.
Performance specifications of a typical production unit shall be as follows: Measured sensitivity (SPL at 1m [3.3 ft] with 4V input, averaged from 100 Hz to 10 kHz) shall be
at least 89 dB-SPL. Usable frequency response shall extend from 75 Hz to 20 kHz (10 dB below rated sensitivity in half-space) with no external equalization. Rated power
shall be at least 75 watts continuous pink noise power, defined as conforming to international standard IEC268-5 (shaped pink noise with peak-to-average ratio of 6 dB) for a
period of 100 continuous hours.
The system shall be protected against damage from occasional overpowering via full range series lamps that limit the power to the network and transducers (Control 26C,
not Control 26CT). The high frequency transducer shall be horn-loaded to more evenly cover a minimum 110° polar conical coverage area.
The backcan shall be constructed of formed steel and the baffle of UL94V-0 fire rated medium impact polystyrene. An enclosed terminal box shall be included proving
strain relief for use with either plenum-rated wire, ½ in (13 mm inside diameter) conduit, or flexible conduit up to 22 mm (⅞ in) outside diameter. The external wiring shall
be accomplished via a removable lockable wiring connector with screw-down terminals to provide both secure wire termination and prewiring capability before loudspeaker
installation. An attachment loop shall be provided on the back panel for cabling to building structure as a secondary support point.
The system shall include a support backing plate to reinforce the ceiling material and tile support rails for use on either 2 x 4 ft or 600 x 1200 mm suspended ceiling tiles
and which can all be installed from beneath the ceiling tile.
Overall front face diameter shall not exceed 252 mm (9.9 in), overall depth from
the bottom of the ceiling shall not exceed 190 mm (7.5 in), and shall weigh no
more than 3.4 kg (7.5 lb).
Control 26C: Nominal impedance shall be 16 ohms.
Control 26CT: The loudspeaker shall be equipped with transformer for use in
either 70.7 or 100V distributed-line speaker systems, with taps selectable by rotary
switch located on the front panel so that the speaker does not have to be removed
to adjust tap settings. Taps shall be nominally 60W @ 70V, 30W @ 70V (60W @
100V), 15W@ 70V (30W @ 100V), and 7.5W @70V (15W @ 100V).
The loudspeaker shall be the JBL Model Control 26C (Control 26C
