About this Guide
This guide describes the Extron SF 10C SUB, a subwoofer, that is typically installed above
a suspended ceiling. This guide describes how to install, operate, and configure the
subwoofer.
About the SF 10C SUB
The SF 10C SUB (see figure1 on the next page) is a plenum-rated, 8 ohm, 4th order
band-pass subwoofer with a tuned bass-reflex port. When installed, the subwoofer is
typically suspended by wires from the structural ceiling above the suspended ceiling. This
avoids unwanted rattling and vibrating in the ceiling tile grid. It features a 10-inch ported
woofer housed within a cylindrical enclosure. A right-angle port on the front of the enclosure
directs the sound waves into the listening area.
The subwoofer has a frequency range of 25 Hz to 160 Hz, -10 dB, half space.
The SF 10C SUB is compatible with any Extron low impedance amplifier with sufficient
output drive power. The unit is UL 2043 Listed for use in air-handling spaces.
The subwoofer is intended for use in a bi-amplified system. Separate amplifiers should
power the low and high frequencies.
ATTENTION:
The SF 10C SUB is UL Listed for use in plenum airspaces: meets UL 2043 for heat
and smoke release.
Le SF 10C SUB est certifié UL pour une utilisation dans des espaces de plenum:
il est conforme à la norme UL 2043 relative à l’évacuation de la chaleur et de la
fumée.
Suitable for use in environmental air space in accordance with Section 300-22(C)
of the National Electrical Code, and Sections 2-128, 12-010(3) and 12-100 of the
Canadian Electrical Code, Part 1, CSA C22.1.

Troubleshooting
Placement Considerations and Acoustical Reinforcement
Installation Environment
Ceiling placement
The speaker is rated for installation in plenum spaces.
The mounting kit comes with four sets of aircraft cables and cable gripper mounting
hardware for suspending the speaker in a horizontal orientation.
Mounting holes for mounting using unistruts or all thread rods are provided.
Isolation grommets are provided that dampen mechanical vibrations from the
subwoofer to the rest of the structure.
Other than the isolation grommets, the installer must provide the mounting
hardware for unistrut or all thread rod installation.
The mounting holes can also accept hanger wire.
The port tube does not isolate the listening space from the installation space.
Bleed-over into adjacent rooms must be taken into consideration.
Placement behind a wall
When the subwoofer is installed behind a wall, the port tube must be located as close
to the wall surface facing the listening space as possible.
The drywall facing the subwoofer may need to be removed between the studs on either
side of the unit, in order to bring the port tube as close as possible to the front surface
of the wall. In this case, fire blocks must be run in-between the studs, to seal off the
space above the removed portion of the wall.
The optional SMK F SF 10C Plus floor mounting kit must be used when the subwoofer
is placed on the floor and must be strapped to a stud.
SF 10C SUB • Installation 5
Acoustical Reinforcement
Depending on where you mount the subwoofer, such as next to a large, rigid, planar
surface, you can achieve some level of acoustical reinforcement (see figure2).
NOTE: At the frequencies at which the subwoofer operates, fiberglass ceiling tiles are
acoustically transparent and offer little acoustical reinforcement.

SF 10C SUB • Installation 6
Corner mounting (see figure2 on the previous page) — The subwoofer is mounted
in a corner of a surface where three surfaces meet, giving reinforcement from all three
surfaces. This option provides the most reinforcement. The port tube should be as close
to the corner as possible for best results.
Edge mounting (figure2) — The subwoofer is mounted at the edge of a surface
where two surfaces meet, giving reinforcement from both surfaces. This option is as
much as 6 dB less sensitive than corner mounting. The port should be as close to the
edge as possible for best results.
Ceiling, wall, or floor mounting (figure2) — The subwoofer is mounted in or on a
surface in an area away from any other surface. This option is as much as 12 dB less
sensitive than corner mounting. There is reinforcement from only one surface.
Free mounting (figure2) — The subwoofer is mounted away from all walls, the floor
and the ceiling. This option is as much as 18 dB less sensitive than corner mounting.
There is no reinforcement from any surface.
Mounting the Subwoofer
The SF 10C SUB can be suspended in a ceiling or rested on the floor.
Suspending in the Ceiling
WARNING:
AVERTISSEMENT :
Properly suspending equipment requires training and expertise. Improper rigging of
suspended equipment can cause the speaker to fall, resulting in death, personal
injury, equipment damage, and legal liability. Installation must be carried out by fully
qualified installers, in accordance with all required safety codes and standards at
the place of installation.
Il est indispensable de disposer de compétences techniques pour pouvoir
suspendre l’équipement. Une manipulation incorrecte de l’équipement suspendu
peut provoquer la chute de l’enceinte, entraînant la mort, des lésions corporelles,
des dégâts matériels, et engageant la responsabilité d’un individu. L’installation

SF 10C SUB • Installation 7
ATTENTION:
Installation and service must be performed by authorized personnel only.
L’installation et l’entretien doivent être effectués par le personnel autorisé
uniquement.
This unit must be repaired by personnel trained by Extron or returned to Extron for
repair.
Cette unité doit être réparée par un technicien formé par Extron ou renvoyée à
Extron pour réparation.
The subwoofer can be suspended using the included aircraft cables (see “Aircraft cable
installation”) or, optionally, with threaded rods acquired locally (see Threaded rod
installation on page10).
Aircraft cable installation
Suspend the subwoofer above a false ceiling using the included aircraft cables as follows:
Remove ceiling tile and install suspension cables.
For installation with optional threaded rods, see Threaded rod installation.
1. Determine where the subwoofer is to be suspended and its orientation above the
suspended ceiling.
NOTE: Remember that the sound from the unit is directed out the port. Therefore,
although you can suspend the subwoofer in any horizontal orientation, the port
needs to be pointed into the listening space.
Consider the following as you make this determination:
Possible acoustical reinforcement (see Acoustical Reinforcement on page5).
The size (length, width, and height) of the subwoofer.
The desired location of the woofer port. Ensure that the center of the port tube will
be at least 5-3/16 inches (13.7 cm) from the edge of suspended ceiling tile once
that tile is installed.
NOTE: This positioning ensures that the grille adapter and C-ring fit properly
once installed (see figure3).
Do not install the C-ring
beyond the edge of ceiling tile.
Figure 3. Grille Adapter and C-ring Fit
Any obstructions above the suspended ceiling that could constrain the orientation
of the suspended subwoofer.

SF 10C SUB • Installation 8
2. At the location where the subwoofer is to be installed, remove as many ceiling tiles as
necessary to install the subwoofer.
NOTE: The number of tiles to remove depends on the height of the structural
ceiling above the suspended ceiling, given the 10-degree spread from the
subwoofer to the structural ceiling.
At an approximate angle of 10 degrees out from each corner of
where the subwoofer will be installed, mark and drill four holes in the
structural ceiling for the suspension cable anchors.
3. Screw a lag eye bolt (or an appropriate anchor) into each hole.
4. Thread the loose end of the suspension cable through the bolt eyehole,
pass the loose end of the cable through the looped end and tighten.
Allow each cable to hang.
Suspend the main subwoofer enclosure from the ceiling
ATTENTION: The SF 10C SUB is heavy, approximately 38 pounds (17 kg), and bulky.
ATTENTION : La SF 10C SUB est lourde, et pèse environ 17 kg (38 livres), et est
volumineuse.
Use at least two people to install the subwoofer; one person to lift the unit into
position AND to hold it, the second person to fasten the suspension cables.
Il faut au minimum deux personnes pour installer le caisson de grave ; la première
pour mettre l’unité en place ET la tenir, et la seconde pour raccorder les câbles de
suspension.
Consider using a scissor-lift or other lifting apparatus rather than a ladder to work
in the ceiling.
Songez à utiliser une nacelle élévatrice ou tout équipement similaire plutôt qu’une
échelle pour travailler au plafond.
Do not rest the subwoofer on the ceiling grid, even temporarily.
Ne posez pas le caisson de grave sur la grille de plafond, même temporairement.
TIP: If a scissor-lift is not available, the speaker can be hoisted using the suspension
cables.
1. Remove the grommets from all four corners of the subwoofer frame (see figure4 on
the next page).
2. Install the included eyebolts into the four holes on the four corners of the subwoofer
frame. Secure the eyebolts in place with the provided locking nuts (figure4).
3. With the help of at least one other person, carefully lift the subwoofer enclosure into the
installation location.
4. Holding a cable gripper, pass the loose end of one of the cables down through one hole
of the gripper. Ensure that about 12 to 15 inches (30 to 38 cm) of cable has exited the
gripper (figure4).
SF 10C SUB • Installation 9
WARNING:
AVERTISSEMENT :
Maintain at least a 2-inch (5 cm) clearance between the plunger on the cable
gripper and any other object in the ceiling space. This includes the space
between the eyebolt below the gripper and the mounting hardware above the
gripper. If an object strikes the plunger, the cable gripper could disengage and
allow the subwoofer to fall.
Conservez au minimum 5 cm (2") d’espace libre entre le piston sur le serre-
câble et tout autre objet se trouvant dans l’espace plafond. Il s’agit de l’espace
entre l’anneau de levage sous le serre-câble et le matériel de montage au-
dessus du serre-câble. Si un objet heurte le piston, le serre-câble pourrait se
desserrer et entraîner la chute du caisson de basses.

SF 10C SUB • Installation 10
7. Adjust the cable tension through all cable grippers so that the subwoofer appears level
to the critical eye and to ensure that its bottom brackets will be approximately 1 inch
(2.5 cm) from the top surface of suspended ceiling tile once that tile is installed.
NOTE: The exact height of the subwoofer is not critical at this point. You will make
final adjustments after the grille is installed.
Threaded rod installation
Secure the subwoofer to the structural ceiling using threaded rods as follows:
NOTES:
Extron recommends 1/4-inch or 3/8-inch diameter threaded rods for installing this
product.
The threaded rod must be properly secured to the ceiling structure. For example,
properly fasten a unistrut to the ceiling structure and attach threaded rods using
nuts and fender washers.
1. Fasten four threaded rods to the support structure.
Extron recommends fastening the rods to unistruts,
one over each corner of the subwoofer installation
location.
2. Fasten a rod to each corner securing point of the
subwoofer with nuts and fender washers
(see the figure at right).
3. Adjust all the nuts that secure the subwoofer to the
ceiling so that the subwoofer appears level to the
critical eye and to ensure that its bottom brackets will
be approximately 1 inch (2.5 cm) from the top surface
of suspended ceiling tile once that tile is installed.
NOTE: The exact height of the subwoofer
above the ceiling is not critical at this point.
You will make final adjustments after the grille
is installed.
Installing Long Legs for Vertical Installation on a Floor
ATTENTION:
The SF 10C SUB must have firebreaks installed in the wall, above and below it,
when it is protruding through a wall, to meet UL requirements.
Le SF 10C SUB doit disposer de systèmes coupe-feu installés au mur, au-dessus
et au-dessous de l’unité, lorsqu’elle est placée en saillie du mur, afin de satisfaire
les exigences de l’UL.
The subwoofer must be securely fastened to the stud or other stationary surface
when mounted in one of the vertical positions.
En position verticale, le caisson de basses doit être solidement fixé au montant ou

Insert threaded
rods through holes
on the ends of the
mounting bracket.
Attach washer and nut and secure.
SF 10C SUB • Installation 11
The subwoofer can be set vertically on a floor using the optional SMK F SF 10C Plus floor
mounting kit, as follows:
1. Determine where the subwoofer is to be placed and its orientation (port tube on top or
port tube on the bottom).
NOTES:
Remember that the sound from the unit is directed out the port. Therefore, the
port needs to be pointed into the listening space.
To ensure that the Extron grille fits fully into any masking wall or other partition,
the center of the port tube must be at least 5-3/16 inches (13.7 cm) from the
edge of the wall.
The included grille does not fit if you install the legs on the subwoofer with the
port tube down and place the feet directly on the floor. Consider fabricating a
small platform to lift the subwoofer or otherwise design your own way to dress
the installation to give your installation a finished look (see figure6,
3
, on the
next page).
Steps 4, 5, 6, and 9 are necessary only if you are installing the subwoofer in an
adjoining space.
2. Remove the grommets from the holes in the installation bracket.
3. Fasten two legs to each installation bracket using the provided screws and locking nuts,
two on one side of the foot (see figure5,
