Speaker Placement  
The low frequency capability of the CSUB allows great flexibility in its placement.While  
full-range speakers will typically be installed throughout the ceiling in an evenly spread  
pattern, the CSUB can be placed wherever it is most convenient. This usually means  
where the subwoofers best meet the needs of the overall sound system, or may some-  
times mean where they best fit into the ceiling. This flexibility is useful in irregularly-  
shaped rooms or when the depth of the area behind the ceiling surface varies.  
An important performance parameter to keep in mind is that the location of the sub-  
woofer will affect its output sound pressure level (SPL) within a room.Locating the CSUB  
close to a wall will increase its output by approximately 3 dB over locating it toward the  
center of the ceiling area.The 3 dB increase will effectively double the amount of output  
power coming from the subwoofer. Locating the CSUB in the corner of a room, adjacent  
to 2 perpendicular wall surfaces, will increase its output by 6 dB.This 6 dB increase effec-  
tively quadruples the output of the subwoofer compared with locating it closer to the  
center of the room. The tradeoff for this extra output is a less uniform overall sound  
level, especially in large rooms.  
Three possible locations for a CSUB Subwoofer  
within a larger sound system:

Center of Ceiling: Optimum Bass Distribution  
Most Uniform Sound Level

Note:The CSUB may be placed as close as 5" from a wall, provided care is taken to  
ensure that mounting clamps are properly extended (see Installation section). If mount-  
ing clamps cannot be properly extended, another location must be found.

Installation  
The unique clamp-mounting system of the Bogen CSUB not only allows mounting in  
most types of ceiling surface thicknesses, it takes the ease of installation two significant  
steps further:  
1. NO TILE BRIDGE IS REQUIRED. Because the mounting clamps are extra-long and  
very durable, they can suspend and support the CSUB across the 24" span of a  
suspended ceiling.This eliminates the need for the separate tile bridge required  
for nearly all ceiling speakers.  
2. A uniquely designed clamp screw assembly can be tightened from either the front or  
rear, allowing the CSUB to be mounted either by dropping the ceiling tile onto  
the rear of the CSUB or by dropping the CSUB into the front of the ceiling tile.  
This design can significantly accelerate the installation process.  
IMPORTANT  
There must be a minimum of 11" of vertical clearance (12-1/4" if using the CK10  
Safety Cable Kit) between the front of the mounting surface and any other  
structure in the ceiling for the speaker to fit. Before cutting the full hole, inves-  
tigate for depth and clearance by cutting a small hole, or removing the ceiling  
tile, whichever is applicable.  
SUSPENDED CEILINGS:The clamps must be able to span the full 24" (approx.)  
between the ceiling rails to provide the proper support for the CSUB. If there  
is interference with any objects in the ceiling to prevent this,then another ceil-  
ing tile location should be chosen.  
DRYWALL or OTHER Hard Ceiling Surfaces:The edge of the hole must have clear-  
ance of at least 5" on opposite edges of the hole to ensure that the clamps will  
be able to support the CSUB.

Installation (cont.)  
SUSPENDED CEILINGS:  
1. Remove the ceiling tile from the ceiling grid. Cut a 14-1/4" circular hole in the ceil-  
ing tile. Use the included template as a guide.  
2. Put the CSUB face down on a workbench or on the floor without grille installed.  
3. Place the ceiling tile over the CSUB, making  
2×2 CeilingTile  
sure the ceiling tile is facing out.It is impor-  
Mounting clamps (×4)  
tant to note the direction of the clamps:  
they must be installed so that they span the  
distance from one side of the ceiling tile to  
the other (approx. 24", see illustration at  
right). The front of the CSUB is  
engraved with guide arrows for “24-  
Inch Ceiling Tile” (see Product  
Diagrams section). Use these guides  
for this installation.  
4. Using an electric powered screwdriver with the  
clutch at a low setting, tighten each screw  
until the clamps are just snug against the  
tile surface. The CSUB’s clamps can be  
tightened from either the front or rear of  
the speaker. Use a No. 3 Phillips screwdriv-  
Mounting clamps extend  
to, but do not overhang,  
edge of ceiling tile.  
Support rail  
er when working from the front. Use a 1/4" flat-blade screwdriver when work-  
ing from the rear. If working from the rear of the speaker, the screws tighten  
COUNTERCLOCKWISE. Do not over-tighten clamps. Once all four clamps  
are properly positioned and snug on the ceiling tile, the assembly (CSUB and  
ceiling tile) is ready to be mounted in the ceiling grid.  
5. Before installing the grille, make sure you have selected the proper power setting on  
the front panel rotary switch. Refer to the Selecting Power Levels section for  
instructions on selecting the power level. Install the grille as indicated in the  
Speaker Grille Installation & Removal section.  
6. Before mounting the CSUB/tile assembly, make sure the snap-lock input connector  
has been connected to the input wires (see Speaker Wiring section). The  
CSUB/tile assembly may now be placed in the ceiling grid. By accessing the ceil-  
ing space through an adjacent ceiling tile, plug in the snap-lock connector.Attach  
the Terminal Cover using the screws provided. If using conduit, refer to the  
Terminal Cover section of this manual.  
7. Attach the CK10 Safety Cable, if it is being used, by screwing the eyebolt into the  
safety tether point in the rear of the CSUB’s metal enclosure (see Product  
Diagrams).This may be a local code requirement. It is certainly a very good safe-  
ty measure, particularly in suspended ceiling installations. For more information  
see the instruction sheet included with the CK10.

Installation (cont.)  
DRYWALL OR OTHER HARD SURFACES:  
1
Be sure you know the location of the ceiling joists before cutting the speaker open-  
ing. Cut a 14-1/4" circular hole where the CSUB will be installed.Use the includ-  
ed template as a guide.  
2. Make electrical connections to the snap-lock input connector and then plug it into  
the CSUB (see SpeakerWiring section).  
3. Install terminal cover using the supplied screws. If using conduit, refer to the Terminal  
Cover section of this manual.  
Mounting clamps extend to joists.  
4. Place the CSUB in the ceiling cut-out. To help  
properly place the CSUB in the ceiling,  
the front of the CSUB is engraved with  
guide arrows for “14-1/2" Joist Space”  
(see Product Diagrams, #6). Use these  
guides for this installation.  
Important:  
Be certain to position the subwoofer so that  
the engraving “14-1/2" Joist Space” aligns  
perpendicularly between the studs. Failure to  
do so may result in the clamps being unable  
to swing out far enough to seat the speaker  
properly.  
14-1/2 Inches between ceiling joists.  
5. Using an electric screwdriver with the clutch at a low setting, tighten each clamp  
screw until the clamps are just snug against the ceiling surface. Once all four  
clamps are snug on the ceiling, the four clamp screws should be tightened with  
the next clutch setting or with a hand screwdriver. Do not over-tighten clamps.  
6. Before installing the grille, make sure you have selected the proper power setting on  
the front panel rotary switch. Refer to the Selecting Power Levels section for  
instructions on selecting the power level. Install the grille as indicated in the  
Speaker Grille Installation & Removal section.

Speaker Wiring  
All wiring should be done prior to installation and  
then plugged into the rear of the speaker.Wiring is  
terminated at a snap-lock input connector. There  
are two positive and two negative terminals to  
accommodate daisy-chaining of speakers in a sys-  
tem.  
Daisy-Chaining  
The snap-lock input connector allows for easy  
daisy-chaining of speakers by providing a second  
terminal of each polarity. See the figures to the  
right and below for correct wiring for daisy-chain-  
ing of terminals.  
Note: When speakers are daisy-chained, disconnecting one speaker from the chain  
will disable all speakers further down the chain.  
Speaker Polarity  
Keep the same polarity terminals wired together to ensure correct speaker polarity. In  
order to provide the best possible sound, all speakers – both subwoofers and full-range  
speakers – in a system need to be pushing out and pulling in at the same time.Therefore  
all must be wired with the same polarity.  
If the connections to one speaker in a system are reversed from the others, that speak-  
er’s movement will be out of polarity with the other speakers.This results in a loss of low  
frequency response and will effect the overall performance of the system.  
Terminal Cover  
The terminal cover is attached to the back of the speaker housing using 2 screws. It is  
important that both screws be used to mount the cover.  
A slot in the terminal cover allows the wires to exit the speaker while protecting the  
connections.  
If local codes require the use of a conduit for connections or strain relief of the connec-  
tions, a circular knockout can be removed and a proper fitting installed to meet these  
requirements.

Selecting Power Levels  
The front-mounted selector switch is used to set the  
appropriate power level or impedance for your system.  
Using your fingers or a flat-blade screwdriver, turn the  
knob until the arrow points to the power level you  
require.  
70V Systems  
A power setting scale for 70V systems is labeled on the  
switch. Six settings are available, from 2 to 64 watts.  
8-ohm Systems  
The fully counterclockwise position of the setting switch is the 8-ohm position.This set-  
ting is suitable for use with low-impedance amplifiers that typically support 4- or 8-ohm  
speakers.  
Speaker Grille Installation & Removal  
Installation  
The speaker grille fits tightly! Push the speaker grille in  
until it can go no further.Then, slap around the edge of  
the grille to seat the grille. The grille is properly seated  
when it is flush with the edge of the bezel.  
Note: Black butyl rubber tape is included for extra security in holding the grille in  
place.Cut four small pieces and space them equidistant around the groove in the baf-  
fle where the grille fits.The butyl rubber tape is quite sticky and it is not necessary  
to use an excessive amount.  
Removal  
Insert a pocketknife blade between the grille and the  
bezel about 1/4" deep and then gently pry the grille  
upwards. Do this in multiple places around the  
circumference of the grille to free the grille.
