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.

Removing the Speaker from the Mounting Plate
WARNING: All structural steps and electrical installation must be performed by qualified
personnel in accordance with local and national building codes and electrical codes. Since applications can vary considerably, it is the responsibility of the installer to exercise good judgment when selecting the mounting location, method, 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.

Installing the Speaker Mounting Plate
10° Mounting Adapter
Catch Tab
Vertical Mounting
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.
0° Mounting Plate

The mounting plate can be installed vertically or horizontally, as shown below.

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.

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.

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.
