About this Guide
This guide describes the Extron SM 28 surface mount speaker and discusses how to install,
configure, and operate it.
In this guide, the terms “SM 28” and “speaker” refer to the SM 28 surface mount speaker.
About the SM 28 Surface Mount Speaker
The Extron SM 28 SpeedMount Surface Mount Speaker is a two-way speaker with a
patent-pending, concealed wall mounting system. It features an 8-inch (20.3 cm) woofer
with dual tuned ports and a 1.1-inch (2.8 cm) tweeter. Speaker mounting incorporates a
separate mounting plate that can be attached directly to a wall. The speaker wiring attaches
to the mounting plate so that the speaker can easily slide into the mounting plate, making
electrical contact between the plate and the contacts on the speaker. A built-in locking
mechanism between the speaker and the mounting plate also prevents the speaker from
being removed by unauthorized personnel. A release on the speaker baffle allows for
quick removal from the mount. The release is lockable and hidden, and together with the
concealed speaker wiring contacts, helps to deter theft.

and hardware. Extron is not responsible for damages resulting from the negligent
installation of any mount or speaker.
AVERTISSEMENT : Toute étape structurelle et installation électrique, doit être
effectuée par un personnel qualifié, conformément aux codes du bâtiment, aux codes
incendie et sécurité, et aux codes électriques, locaux et nationaux. Étant donné
l’éventuelle variation importante des applications, il incombe à l’installateur d’agir avec
discernement lors de la sélection de l’emplacement, de la méthode et du matériel de
montage. Extron ne sera pas tenu responsable des éventuels dommages résultant de
la mauvaise installation des attaches de montage ou des enceintes.
SM 28 Surface Mount Speaker • Installation 5
Installing the Speaker Mounting Plate
The SM 28 speaker comes with a flat mounting plate and an adapter for positioning the
speaker 10° up, down, left, or right.
• 0° mounting plate — The flat (0°) mounting plate allows the speaker to be mounted flat
on a suitable surface.
• 10° mounting adapter — The 10° mounting adapter allows the speaker to be installed
at a 10 degree angle so that the speaker can be pointed up, down, left, or right from an
elevated position by rotating the adapter.

Mounting to a Wall Stud
NOTE: Mounting hardware not provided.
1. Locate the wall stud where the mounting plate will be installed.
2. If using the 10° mounting adapter, position the adapter to the wall stud according to how
the speaker will be angled and mark the positions of the pilot holes. See the figure below
for mounting hole locations.

Figure 4. Mounting the Adapter
If not using the adapter, position the mounting plate against the wall. The #28 arrow
molded into the mounting plate indicates the vertical midpoint of the SM 28 speaker
when it is mounted on a wall stud. While positioning the mounting plate on the wall,
mark the location of two pilot holes using the holes indicated below.

Figure 5. Positioning the Mounting Plate
NOTE: A speaker wire access hole (see figure 6 on the next page, and figure 8
on page 8) must also be cut in the wall, so mark that hole location now with the
mounting plate positioned on the wall while ensuring that the wall stud does not
interfere with the wire routing and that the mounting plate hides the access hole.
3. Drill the mounting plate pilot holes and cut the speaker wire access hole, as previously
marked.
4. Install the speaker cables into the wall before installing the speaker mounting plate.
Leave enough slack in the cable.
5. The SM 28 can be mounted with or without the 10° mounting adapter. In either case,
the wiring of the quick connect contacts remains the same, but the wire routing will vary.
SM 28 Surface Mount Speaker • Installation 7
Routing the wires without the 10° mounting adapter
Route the speaker cable through the rear of the 0° mounting plate and attach the wire
ends to the quick connect contacts using a small screwdriver, as shown below. Be sure
to observe the correct polarity.

6. Attach the mounting plate to the wall, as shown below.
ATTENTION:
• Use the appropriate mounting screws. The screw heads must not protrude
more than 0.27 inch (7 mm) above the screw holes in the mounting plate (see
the figure below). If the screw head protrudes too far above the mounting plate
surface, damage to the speaker may occur when the speaker is attached.
• Utilisez les vis de montage appropriées. Les têtes de vis ne doivent pas
dépasser plus de 7 mm (0,27 pouces), au-dessus des trous de vis situés
dans la plaque de montage (voir figure de droite). Si la vis dépasse largement
la surface de la plaque de montage, l’enceinte est susceptible de subir des
dommages lors de son rattachement à la plaque.

Mounting the SM 28 Using the Yoke Mount Kit
The SM 28 can be mounted using the optional yoke mount kit. Refer to the Yoke Mount Kit
Setup Guide for installation details.
Attaching a Secondary Support Cable
If a secondary support cable is being attached, attach the cable to the eye bolt, as shown
below. The cable end should be properly swaged.

SM 28 Surface Mount Speaker • Installation 12
Attaching the Speaker to the Mounting Plate
ATTENTION:
• By default, the SM 28 speaker is shipped unlocked. When mounting the speaker
to the mounting plate, be sure that the speaker is unlocked. Failure to place
the speaker in the unlocked position will result in damage to the speaker lock
mechanism should an attempt be made to mount a locked speaker (see “Using
the Security Key to Lock and Unlock the Speaker” on page 14).
• Par défaut, l’enceinte SM 28 est livrée en mode déverrouillé. Lors du montage de
l’enceinte sur la plaque de montage, assurez-vous que l’enceinte soit déverrouillée.
Si elle n’est pas déverrouillée avant son montage sur la plaque, elle pourrait subir
des dommages au niveau de son mécanisme de verrouillage (voir « Utiliser la clé de
sécurité pour le verrouillage et le déverrouillage de l’enceinte »).
NOTE: If the secondary attachment point is being used, see the “Attaching a
Secondary Support Cable” on the previous page for installation details before
proceeding further.
Position the rear mounting slot of the speaker above the catch tab of the mounting plate,
then slide the speaker down into the mounting plate until a click is heard indicating that
the speaker is secured in place (see figure below). When properly seated, the speaker
connections are automatically made.

Using the Security Key to Lock and Unlock the Speaker
Insert the key into the center of the speaker grille and turn the key, as needed, so that
the speaker is in the unlocked position (see the figure below). There are three small raised
“dimples” (see the figure on the next page) on the grille surface that surrounds the keyhole.
Repeat this procedure, but set the key to the locked position to lock the speaker.
ATTENTION:
• The key must be rotated to the unlocked position before the speaker is attached to
the mounting plate. Failure to place the speaker in the unlocked position will result
in damage to the speaker lock mechanism should an attempt be made to mount
the speaker. By default, the SM 28 speaker is shipped unlocked.
• La clé doit être basculée en mode déverrouillé avant le rattachement de l’enceinte
à la plaque de montage. Si l’enceinte n’est pas placée en mode déverrouillé, elle
pourrait subir des dommages au niveau de son mécanisme de verrouillage lors
de son montage sur plaque. Par défaut, l’enceinte SM 28 est livrée en mode
déverrouillé.
