descriPtion

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 Integrat or® Series speaker is ideally suited for small to medium classrooms
and conference rooms where surface mount speakers are desired, but wall space for speaker
placement is limited. With a weather-resistant construction, the SI 3 is also at home in many
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.

s P eA ke r s

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.

extron conicA l bA ff le

A compact surface mount speaker is a logical choice when wall space is at a premium. To
address the issue of beaming in the midrange and high frequencies that can be found in a small,
compact speaker, the SI 3 has been designed with a 3" full-range driver that is acoustically
coupled to an Extron exclusive conical baffle. This baffle serves as a waveguide to help create a
wide dispersion profile. With this very broad conical spreading of the mid and high frequencies,
two SI 3 speakers in a small to medium classroom should ensure consistent volume levels for
everyone while delivering increased intelligibility and accurate music reproduction.

Surface mount speakers are mounted onto walls, and therefore require considerable
flexibility in terms of where and how they can be installed. F or integrators, a number of
challenges exist in the successful installation of surface mount speakers in an instructional or
commercial environment.

•

When installing a speaker, the installer is often working at an elevated height, performing

a delicate, tedious balancing act by supporting the speaker in place with one hand, and
securing it to the mounting hardware by tightening with the other hand cramped behind
the speaker.

•

The speaker must not only be installed securely, but also properly aimed at the listening

area. This is likely to require trial-and-error by first loosening the hardware, aiming the
speaker while supporting it in place, re-tightening the hardware, and then repeating if
necessary. The speaker often shifts while the installer tightens the hardware.

•

Surface mount speakers, similar to projectors, are subject to theft because of their open

exposure to potential vandals. Speakers can be removed simply by detaching them from
the mounting hardware.

To address these challenges, Extron has developed V-Lock, an exclusive, Patent Pending
speak er moun ting sy stem that is included with ea ch SI 3 surfa ce moun t sp eaker.
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 which is integral to the speaker. It
is sold in pairs and available in black or white.

Procedure

•

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 horizontal and 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.
