The Extron SI 3 compact surface mount speaker features a 3" (7.6 cm)
full-range driver coupled to an exclusive conical baffle that enhances
coverage throughout the listening area. The driver features an
incredibly wide frequency response of 75 Hz to 18 kHz, and 16 watts
continuous pink noise and 32 watts continuous program capacity. An
internal overload protection circuit prevents driver damage due to
excessive input levels.
This System Integrator Series speaker is ideally suited for small
to medium classrooms where wall space is at a premium due to
projector screens, pull-down maps, and white boards. With a
weather-resistant construction, the SI 3 is also at home in outdoor
environments.
The exclusive conical baffle provides a broad dispersion of the mid
and high frequencies in order to optimize room coverage from a
compact speaker. Voice intelligibility is critical for classrooms and
many other applications, and the SI 3 provides excellent voice clarity
without compromising music reproduction.
Included with the SI 3 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 3 is sold in pairs and is available in a black or white finish, and
includes a 5 year parts and labor warranty.
