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 wire 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.

The SF 10C SUB is UL Listed for use in plenum airspaces: meets UL 2043 for heat and

smoke release.

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. The product has been additionally investigated to

UL 2043, "Fire Test for Heat and Visible Smoke Release for Discrete Products and Their

Accessories Installed in Air-Handling Spaces".

SF 10C SUB • Introduction 3

Features

• 10-inch (254 mm) low frequency driver with a tuned port — Designed specifically

for low frequency extension.

• UL 2043 rated, rigid composite enclosure — Enclosure remains out of view when

suspended above the ceiling grid.

• Frequency range: 25 Hz to 160 Hz

• 800 watts continuous program

400 watts continuous pink noise — Power capacity per IEC 60268-5

• 8 ohm operation — Direct low impedance power avoids low frequency transformer

distortion.

• Suspension mounting above the ceiling structure greatly reduces rattle —

Physically isolated from the ceiling grid, low frequency vibrations are not transferred to

loose structural components.

• 4th order bandpass enclosure design — High output with controlled and clean low

frequency extension

• No crossover needed when used with SF 26CT, SF 3C LP, or SF 3CT LP ceiling

speakers — Eliminates phase problems at a crossover point.

• Includes installation and suspension hardware — Four sets of 15-foot (4.6 m)

steel cables with locking adapters are used to raise the SF 10C SUB into place and

suspend it.

• Includes C-ring and paintable grille — Port output into the room blends in with

ceiling speakers.

• Paintable enclosure — The SF 10C SUB enclosure can be painted with a plastic-

friendly paint.

• Integrated flame arrester for safety — Restricts flammability for plenum installations.

• 5-year parts and labor warranty

Installation

This section describes the installation and the operation of the SF 10C SUB, including:

• Placement Considerations and Acoustical Reinforcement

• Mounting the Subwoofer

• Mounting the Port Tube

• Installing the Grille

• Connection and Operation

• 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 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 for Discussion of 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 (see 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

wall as possible for best results.

• Ceiling, wall, or floor mounting (see 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 (see 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 suspeded 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 doit

être effectuée par des installateurs hautement qualiﬁés, conformément à l’ensemble

des codes et des normes de sécurité réglementaires sur le lieu de l’installation.

• The legal requirements for suspending equipment vary from country to country.

Extron strongly recommends that you consult your local safety standards ofﬁce

before installing any product. Extron also recommends that you thoroughly check

any laws and bylaws prior to installation.

• Les conditions juridiques relatives à la suspension d’équipements varient de pays

en pays. Extron vous recommande vivement de consulter les standards de sécurité

en vigueur dans votre pays avant d’installer un produit. Extron vous recommande

également de vériﬁer minutieusement toute loi et tout règlement avant l’installation.

SF 10C SUB • Installation 7

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.

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.

SF 10C SUB • Installation 8

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 (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 (see 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 (see figure 4).

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.

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 (15 cm) of cable comes through the other end of the gripper.

6. Repeat steps 4 and 5 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

ﬁnal adjustments after the grille is installed.

SF 10C SUB • Installation 10

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.

SF 10C SUB • Installation 11

Resting 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.

• Le caisson de grave doit être solidement ﬁxé au montant ou à une autre surface

stationnaire.

The subwoofer can be rested on a floor using the optional SMK F SF 10C 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).

NOTE:

• 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 grille will not ﬁt if you install the feet on the subwoofer with the port

tube down. Consider fabricating a small platform to lift the subwoofer (see

ﬁgure 6,

on the next page) or otherwise design your own way to dress the

installation to give your installation a ﬁnished look.

• Steps 3, 4, 5, and 8 are only necessary if you are installing the subwoofer in an

adjoining space.

2. Fasten two feet to each installation bracket using the provided screws and locking nuts,

two on one side of the foot (see figure 5,

), and one on the other side (

3. When installing in an adjoining space — On the far side of the wall (outside the

listening space), remove enough wall material so that the subwoofer port tube can be

placed as close to the wall (facing the listening space) as possible.

SF 10C SUB • Installation 12

4. When installing in an adjoining space — On the near side of the wall (inside the

listening space), 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 (see figure 3 on page 7) if the grille will be used (see Installing the

Grill on page 13).

5. When installing in an adjoining space — On the near side of the wall (inside the

listening space), mark and cut the hole in the surface.

6. Place the subwoofer in the desired location.

7. Use a locally-obtained perforated metal hanger strap to secure two of the mounting holes

on the top bracket to the nearest stud or other stationary surface (see figure 6,

Mounting the Port Tube

1. Orient the port tube so that it is pointed into the listening space (see figure 7).

2. Using the included hardware, mount the port tube to the speaker.

Installing the Grille

NOTE: For ceiling tile installation, if the ceiling tile is not removed for the subwoofer

installation, remove it.

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.

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.

5. Place the grille adapter on the opposite side of the installation surface (see figure 8 on

the next page) and use a Phillips screwdriver to turn the three locking arms to loosely

mate the adapter to the C-ring.

Locking Arms

Figure 8. Installing the Grille Adapter

6. Rotate the C-ring and grille adapter such that the locking arms do not collide with the

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

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 not be

used as a tightening guide due to the risk

of overtightening. See the ATTENTION below.

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, 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.
