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.
