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 on the next page) is a plenum-rated, 8 ohm, 4th order figure1
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.

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.

Figure 2. Mounting Locations with Regards to 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 :

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 on page5).Acoustical Reinforcement
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.

volumineuse.
Use at least two people to install the subwoofer; one person to lift the unit into
position to hold it, the second person to fasten the suspension cables.AND
Il faut au minimum deux personnes pour installer le caisson de grave ; la première
pour mettre l’unité en place la tenir, et la seconde pour raccorder les câbles de ET
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 on figure4
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 ( ).

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.

subwoofer.
7. Use a Phillips screwdriver to tighten the three locking arms to clamp the adapter to the
C-ring.
NOTE: For installation in rigid vs. soft material:
Rigid material — Three locking arm screws use
built-in Opti-Torque indicator rings that snap and
separate from their plastic rings when the screws
are tightened to the correct torque. The indicator
ring falls down the screwdriver shaft. When
this occurs, stop tightening the screw to avoid
overtightening the locking arms to the C-ring (see
the figure at right).
Soft material — Because fiberglass ceilings and
other soft materials are not as rigid as mineral tiles
and other hard materials, the Opti-Torque indicator
should be used as a tightening guide due to the risk of overtightening. See not
the ATTENTION below.
Opti- rque RingTo
SF 10C SUB • Installation 16
ATTENTION:
To avoid damaging or deforming soft ceiling material, tighten the locking arms
to secure the grille adapter, but short of causing the grille adapter to deform
the flat mounting surface of the ceiling.

8. Affix the metal grille to the magnetic grille adapter.
9. Adjust the position of the subwoofer relative to the installation so that the subwoofer
appears level to the critical eye and is centered over the grille. Ensure that the port
tube is as close as possible to the installation surface without touching it.
NOTE: Do not allow the port tube or any part of the subwoofer to touch the
installation surface. Undesired audio vibrations can occur.
Connection and Operation
Connection
NOTES:
Pair the 8-ohm subwoofer with an amplifier that outputs up to 800 watts at
8 ohms.
Consider the distance between the subwoofer and the amplifier and whether
doubling up the speaker cable (see on page18) is necessary to
figure13
reduce the power losses through the wires.
Avoid audio clipping:
Ensure that the audio source does not clip the input stage of the amplifier
(check the specifications of the amplifier)
Ensure that the audio signal does not clip the output stage of the amplifier
(check the limiter or protection indicators on the amplifier).
Apply a limiter to the amplifier channel that drives the SF 10C SUB.
No crossover is needed when the subwoofer is used with SF 26CT, SF 3C LP, or
SF 3CT LP ceiling speakers.

3. Strip 3/16 inch (5 mm) of the cable insulation from the wire ends.
NOTES:
The length of exposed wires is important. The ideal length is 3/16 inch (5 mm).
If the stripped section of wire is longer than 3/16 inch, the exposed wires
may touch, causing a short circuit.
If the stripped section of wire is shorter than 3/16 inch, wires can be easily
pulled out even if tightly fastened by the captive screws.
Do not tin the leads before installing them in the connector. Tinned wires are
not as secure in the connector and could be pulled out.
4. Connect four or two speaker wires to the captive screw connector, as shown by the
following two methods (see figure13).

Operational Considerations
Play content that you are familiar with through the system and verify that it sounds as
expected.
Set the gain structure through the audio system appropriately.
Set the gain on the subwoofer and speakers such that they are at the same sound
pressure level.
If any distortion is heard, you may be driving the subwoofer too hard and may need to
add additional subwoofers to the system to get the desired sound pressure level.
Mounting a NetPA U or XPA U Amplifier to the SF 10C SUB
The included amplifier mounting kit attaches an Extron Ultra Series Power Amplifier
(XPA U 2002 SB, NetPA U 2002 SB, or NetPA U 8001 SUB) to the back of an SF 10C SUB.
This kit enables the amplifier to be mounted as close as possible to the subwoofer, allowing
for the shortest possible speaker wiring.
Use the amplifier mounting kit to mount an Extron XPA U 2002 SB, NetPA U 2002 SB, or
NetPA U 8001 SUB Power Amplifier to the SF 10C SUB as follows:
NOTE: If the SF 10C SUB is being installed into a plenum airspace, the AC input of the
power amplifier must be replaced with the Flexible Conduit Adapter Kit. For detailed
instructions for the installation of this adapter kit, see the user guide for the amplifier to
be installed, at www.extron.com.

Troubleshooting
Symptom Description Solution
A “chuffing” sound
is coming from the
subwoofer.
Distortion due
to port tube
placement
Check the placement of the port
tube. Move the tube opening slightly
away from the grille surface to reduce
distortion.
This reduces the output level
slightly, a trade-off that must be
managed.
Distortion due
to overdriven
subwoofer
Attenuate the signal to the subwoofer.
If the desired sound pressure level
cannot be achieved at the new setting,
consider relocating the subwoofer
to a more favorable location (for
example, edge or corner mounting —
see on
Acoustical Reinforcement
page5) and swapping fiberglass
tiles (if used) for mineral tiles.
If the desired sound pressure level still
cannot be met, then the listening space
requires more subwoofers.
