SF 10C SUB Subwoofer • Setup Guide (Continued)
Remove ceiling tile and install suspension cables
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:
Do not install the C-ring
beyond the edge of ceiling tile
.
• The size (length and width) 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 the figure at right).
• Any obstructions above the suspended ceiling that could constrain the
orientation of the suspended subwoofer.
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-degrees spread from the subwoofer to the structural ceiling.
3. 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.
4. Screw a lag eye bolt (or an appropriate anchor) into each hole.
5. 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
Thread the cable down through the cable gripper, through the eye
of one of the eyebolts, and back up through the lock.

(see the figure at right).
2. Install the included eyebolts through the provided countersunk
washers and into the four holes on the frame. Secure the eyebolts
in place with the provided locking nuts.
3. With the help of at least one other person, carefully lift the
subwoofer enclosure into the installation location.
4. Pass the loose end of one of the cables down through one hole of
an included cable gripper. Ensure that about 12 to 15 inches (30 to
38 cm) of cable has exited the gripper.
5. Pass the loose end of the cable through the eye of one of the eye
bolts on the subwoofer enclosure and then through the other hole
in the cable gripper. Ensure that at least 1 inch (2.5 cm) of cable
comes through the other end of the gripper.
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.
6. Repeat steps 3 and 4 for each corner.
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 nal
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 should be properly secured to the ceiling structure. For example, properly
fasten a unistrut to the ceiling structure and attach threaded rods using nuts and 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 (see the figure at right).
2. Fasten a rod to each corner securing point of the subwoofer with nuts and washers.
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 is not critical at this point. You will make nal
adjustments after the grille is installed.
Insert threaded
rods through holes
on the ends of the
mounting bracket.
Attach washer and nut and secure.

Mounting the Port Tube
1. Orient the port tube so that it is pointed into the listening
space (see the image at right).
2. Using the included hardware, attach the port tube to the
speaker.
Installing the Grille
1. If not already accomplished, on the installation surface,
mark where the center of the port tube faces the
installation surface. The center mark must be at least
5-3/16 inches (13.7 cm) from the edge of the installation
surface.
NOTE: For ceiling tile installation, if the ceiling tile is
not removed for the subwoofer installation, remove it.
2. If not already accomplished, using the included grille
cut-out template, mark and cut the hole in the surface.
3. For ceiling tile installation, replace the ceiling
tile in the grid.
4. Place the C-ring on the subwoofer side of the
installation surface and center it over the hole
(see the image at right).
5. Place the grille adapter on the opposite side
of the installation surface and use a Phillips
screwdriver to turn the three locking arms to
loosely mate the adapter to the C-ring.
6. Rotate the C-ring and grille adapter such that
the locking arms and the C-ring do not touch
the subwoofer.
7. Use a Phillips screwdriver to tighten the three
locking arms to clamp the adapter to the
C-ring.
ATTENTION:
• To avoid damaging or deforming soft ceiling material, tighten
the locking arms to secure the speaker, but short of causing the
speaker to deform the flat mounting surface of the ceiling, as seen
from below.
• Afin de ne pas endommager ni altérer un plafond souple, serrez les
bras de verrouillage pour sécuriser l’adaptateur en grille, en veillant
cependant à ce que l’unité ne cause l’altération de la surface de
montage plane du plafond, comme illustré ci-dessous.

NOTE: For installation in rigid vs. soft material:
• Rigid material — Three locking arm screws use 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 image 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 not be used as a
tightening guide due to the risk of overtightening (see the ATTENTION, above).

8. Affix the magnetic grille to the 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
Congure the cable conduit access plate and captive
screw connector as follows:
1. Loosen the cable conduit access plate screw and
remove the plate before wiring the subwoofer (see
the figure at right).
2. Configure the cable conduit access plate, using
either of the following methods:
• When not using flexible conduit: Route the
speaker wires through the cable clamp (see
figure1,
1
).
• When using flexible conduit: Remove the
cable clamp and install the flexible conduit into
the plate opening. Secure the flexible conduit
to the plate with the locking nut and pull the
speaker wires from the flexible conduit (

Extron Safety and Regulatory Compliance Guide on the Extron website.
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 by one of two methods, as shown in the following two examples:
