SI 26
The Extron SI 26 is a two-way surface mount speaker featuring a ferrofluid-cooled,
aluminum dome tweeter coupled to an Extron exclusive, new conical horn design
for minimum phase shift and a flat response over the mid- and high-frequency
ranges. A long-throw woofer with large magnets provides solid low-frequency
response. This System Integrator
®
Series speaker is ideally suited for classrooms,
conference rooms, and boardrooms, and features a weather-resistant enclosure
for use in outdoor environments.

DIMENSIONAL DRAWINGS
The Extron SI 26 two-way surface mount speaker features a ferrofluid-
cooled, aluminum dome tweeter coupled to an Extron exclusive,
new conical horn design for minimum phase shift and a flat response
over the mid- and high-frequency ranges. Harsh tonal qualities due
to cancellation in portions of the frequency range caused by phase
shifting are all but eliminated with this new conical horn design. A
long-throw woofer with large magnets provides solid low-frequency
response. A new approach to crossover design assures a smooth
transition from bass through midrange to the high frequencies,
delivering optimum voice and music reproduction. An input power-
limiting protection circuit is included for preventing woofer and
tweeter damage due to overdriving.
This System Integrator Series speaker is ideally suited for classrooms,
conference rooms, and boardrooms, and with a weather-resistant
construction, is at home in outdoor environments.
The SI 26 features a 6.5" (16.5 cm) long-throw woofer, a 1"
(2.5 cm) tweeter, 150 watts continuous program capacity, and
frequency response from 70 Hz to 20 kHz. This speaker has a nominal
impedance of 8 ohms with a durable, high-impact housing.
Included with the SI 26 is Extron’s exclusive patent pending V-Lock
mounting hardware, which facilitates easy, secure installations and
allows for wide 60° horizontal and 55° vertical travel.
The SI 26 is sold in pairs and is available in a black or white finish,
and includes a 5 year parts and labor warranty.

FEATURES
Extron Conical Horn
Exclusive to the Extron SI 26 is a conical horn design that works in
conjunction with the tweeter and phase plug to deliver minimal
phase shift and flat frequency response over the midrange and
high frequencies. Phase distortion is caused by a mismatch in
dispersion patterns from the woofer and tweeter at the crossover
frequency. This results in a harsh tonal quality characteristic of
frequency cancellation caused by phase shifting.
The Extron conical horn acts as a waveguide to create a wide
dispersion pattern for the tweeter that closely matches that of
the woofer, so that frequencies from both drivers are smoothly
merged together and the audio quality is improved and more
natural-sounding. The phase plug further contributes to the flat
frequency response and minimized phase shifting by working
with the highest frequencies emanating from the tweeter to
increase dispersion and reduce phase distortion.
Extron V-Lock Speaker Mounting System
Integrators are confronted with a number of challenges in
the successful installation of surface mount speakers. To
address these challenges, Extron has developed V-Lock,
an exclusive, patent pending speaker mounting system,
included with each SI 26 surface mount speaker.
V-Lock simplifies installation and substantially reduces the
effort required to place and correctly position wall-mounted
speakers, while also offering theft deterrence. V-Lock is
comprised of two components, one that is mounted to the
wall, and the other that is integral to the speaker.
• Easily mounts like a picture frame –
After mounting
the V-Lock bracket to the wall, position the speaker so that the “V” rails on the back slide into the
“V” channel of the wall mount. The process is akin to installing a picture frame onto the wall. The
speaker is now fully supported by the mounting hardware, so that a balancing act is no longer
necessary.
• One-step positioning and locking –
Both hands are now free to orient the speaker as desired. Then, using the included tool, fully secure
the speaker to the mounting hardware by tightening the V-Lock mount through the slot on the front grille. The subtle, low profile Extron
badge covers the slot after installation, hiding it from view.
• Wide positioning arc –
V-Lock offers wide 60° horizontal and 55° vertical travel, so that the speaker can be easily positioned to achieve
optimized sound coverage.
• Theft-deterrent design –
The V-Lock mounting hardware is integral to the speaker, making simple detachment impossible. Access to
the hardware is possible only through the front baffle slot, which is concealed. Additionally, only the included tool will work with the
hardware. Therefore, V-Lock provides an effective solution for deterring theft.
