SF 26CT Series
SOUNDFIELD XD 6.5" TWO-WAY CEILING SPEAKERS
FOR PLENUM ENVIRONMENTS
The Extron SoundField® XD SF 26CT models are 6.5"
two-way ceiling speakers for use in standard or restricted
height ceiling environments. With the AV industry's first
UL 2043 listed composite speaker enclosure, the SF
26CT series meets stringent UL requirements for smoke
and heat release in plenum air spaces. A magnetically
attached grille with a thin-edged bezel gives the SF
26CT series a refined appearance on the ceiling. The
SF 26CT series offers direct 8 ohm and 70/100 volt
operation with a behind-the-grille, six position power
tap selector switch. With high impedance taps at 8, 16,
32, and 64 watts, the SF 26CT series can be used in
applications where a high power distributed speaker
system is needed.

FEATURESDESCRIPTION
The SF 26CT series provides a wide and smooth frequency
range and is engineered to ensure excellent on and off axis voice
intelligibility. A power rating of 130 watts continuous program also
gives this speaker plenty of headroom for music reproduction in
moderate to high output systems.
Designed for Pro AV
The SF 26CT series represents a paradigm shift in speaker
technology for pro AV applications. We designed these models from
the ground up with innovative materials, modular construction, and
unique features, to provide significant cost savings and superior
performance.
Voicing Consistency
The SF 26CT Series is voiced consistently with the Extron SF 26PT
pendant speaker to ensure smooth sonic transitions in applications
when the listener moves between drop-ceiling and open-ceiling
areas.
Plenum Rated Composite Enclosure
The ideal speaker enclosure is constructed in such a way as to
avoid internal standing waves and resonances in the enclosure itself.
It must also be lightweight and fire tested for use in plenum airhandling spaces. We were able to achieve all of these requirements
by injection molding the enclosure with a fire resistant composite
material. The result is a rigid, acoustically damped, lightweight,
plenum rated enclosure that is UL 2043 listed.
Magnetically Attached Aesthetically Pleasing Grille
The SF 26CT series features a finely perforated round metal grille
with a thin-edged rounded bezel for a refined appearance on the
ceiling. The grille securely attaches magnetically to the baffle and
quickly snaps into place. An optional square grille is available with
the same finely perforated metal and thin-edged rounded bezel. This
gives the owner, architect, or interior designer an additional choice
for matching the décor. The grilles are white and can be painted to
match the architectural elements of the environment.

Low Profile Back Can - SF 26CT LP
The SF 26CT LP features a 4.2" (107 mm) back can for installation
into restricted height plenum environments. This model can be used
for entire installations or in combination with the similarly voiced
SF 26CT and SF 26PT models, as architecturally required.
Optional Square Grille Kit
The SGK SF26C is for applications
with square design elements
THE CEILING SPEAKER REIMAGINED

DESIGNED FOR THE INTEGRATOR
Two-Piece Design for Installation Flexibility
Shipped as a complete speaker assembly, the SF 26CT series is ideal for both single-trade and division-of-labor
installations. The complete speaker can be installed by a single contractor as a self-contained unit for retrofits and
new construction. For larger projects with multiple trades, the back can and speaker baffle can be separated,
allowing the rough-in contractor to install and fully terminate the back can. Once the job site is clean and secure,
the AV integrator can then easily install the speaker baffle and grille. For both models, the back can and speaker
baffle are available separately for installations with a long period of time between rough-in and final installation.
Mixed Height Plenum Spaces and Consistent Voicing
The application diagram shown below illustrates the use of SF 26CT and SF 26CT LP models within a room when some areas of the room
have restricted plenum space. Since the models of the SF 26CT series are voiced consistently with each other, and use the same drivers,
audible transitions between areas of the room can be minimized.
