The Control®26CT-LS is built on the same
platform as our popular Control 26C and
26CT ceiling loudspeakers and is UL1480
UUMW Listed for use in fire alarm and/or
emergency communication systems.

suited for a wide variety of applications from
casinos and hotels to upscale restaurants and
themed locations. High power handling, wide

the Control 26CT-LS 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 computer-optimized 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.

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

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
material.
The Control 26CT-LS backcan is made of formed steel. 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 Control 26CT-LS includes a 60W multitap transformer
for use in either 70.7V or 100V distributed-line systems. 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.
