CSP-SERIES
Thank you for choosing Senal.
The CSP-series speakers are passive coaxial two-way speakers that provide premium sound
quality for use with 70V or 100V systems and for low-ohm systems.
These high power - low distortion speakers feature wide coverage that evenly distributes high
fidelity audio to fill large and small spaces. All models are ideal for broadcasting announcements
and music reproduction in commercial and residential applications.
The CSP-series ceiling speakers have a multi-tap transformer, which allows flexibility in
configuring multiple speakers of a high-impedance system. It is easily accessed with the multi-
tap selector on the front baffle of the speaker. Low frequencies are enhanced with a vented
port, and precise and smooth high frequencies are delivered by the coaxially mounted 3/4"
titanium-coated tweeter. The sealed backcan enhances overall fidelity by focusing the sound
and preventing the distribution of sound into the surrounding ceiling structure.
Removable locking connectors simplify the process of wiring the speakers. Each speaker comes
with the mounting brackets and hardware necessary for installation. The attachment screw
system makes installation simple while providing a secure mounting connection to most ceiling
types. Secondary support tabs ensure extra security for compliance with building codes. The
speakers can be painted to match ceiling décor.
CSP-162
The CSP-162 is a powerful 150-watt, low-distortion ceiling speaker with a built-in multi-tap
transformer with maximum power of 60W. It features a 6.5-inch woofer and 3/4" titanium-
coated tweeter.
CSP-142
The CSP 142 is a compact 80-watt ceiling speaker with a built-in multi-tap transformer with
a maximum power of 30W. It features a 4-inch woofer and 3/4" titanium-coated tweeter.
Low clearance of 6.25" (15.9 cm) makes it possible to install this speaker into smaller ceiling
spaces.

Setting Up
The CSP-series speakers are designed for easy installation. If
necessary, installation can be accomplished without access above
the ceiling.
Tools needed for installation
▪ Drywall saw
▪ Slotted screwdriver
▪ Phillips head screwdriver
▪ Wire stripper
▪ Pencil
Preparing the ceiling
Drop Ceilings
1. Locate the ceiling tile in which the speaker is to be mounted and
remove the tile from the ceiling.
2. Measure to find the center of the tile and place a mark there. Use
that mark to center the cutout template on the tile. With a pencil,
trace an outline of the cutout template on the tile.
3. Use a drywall saw to cut along the traced
line.
Pro tip: For easy cleanup it’s best to
perform this step while placing the tile over
an open box or trashcan.
4. Replace the ceiling tile into the ceiling.
5. Insert the rails through the hole.
6. Place the rails on either side of the hole so that the inverted “V”
ends of the rails fit over the ceiling grid rails. The flat side of the
rails should rest on the tile, and the side with the pre-cut holes
should stand perpendicular on either edge of the hole.
Note: The rails of the mounting bracket do not attach to the
ceiling grid rails, but suspend over them.
7. Insert the C-ring by angling
it through the hole using
the open end of the ring.
8. Fit the slots of the C-ring over the
rails and attach it by inserting the
bolts through the tabs of the C-ring
and securely tightening the nuts.
9. Pull the speaker wire out so that it
extends beyond the ceiling and gives
you enough length to complete the
installation.
Fixed Ceilings
1. Locate the spot where the speaker will be installed
2. Use a stud finder to locate studs in the ceiling. Make sure they
won’t interfere with your installation. If a stud is near the location
of your hole, make sure that there is 1-inch clearance between the
edge of the hole and the stud.
Pro tip: Drill a small pilot hole and probe inside the ceiling with
a stiff wire to make sure there are no obstructions where you are
planning on placing the speaker.
3. With a pencil, trace an outline of the cutout template on the
ceiling.
4. Use a drywall saw to cut along the traced line and remove the
cutout from the ceiling.
5. Pull the speaker wire out so that it extends beyond the ceiling
and gives you enough length to complete the installation.
Connecting the wiring to the removable locking
connector
CSP-162
1. Open the connector cover plate door.
2. Remove the locking connector from the
socket
3. Strip approximately 1/4" (6 mm) off the
ends of the insulation on the speaker
wires.
4. Insert the exposed ends of the wires
into the connector and tighten the
screw-down terminals using a small flat blade
screwdriver.
CSP-142
1. Remove the cover by unscrewing the two
screws attaching it to the backcan.
1.1. Determine the angle your speaker
wires approach the speaker and
remove the appropriate knockout.
1.2. Feed the wires through the
knockout.
2. Remove the locking connector from the
socket
3. Strip approximately 1/4" (6 mm) off the
ends of the insulation on the speaker
wires.
4. Insert the exposed ends of the wires into
the connector and tighten the screw-
down terminals using a small flat blade
screwdriver.

Wiring Schemes
The removable locking connector has four terminals. The pin
function of each terminal is listed on the label located on the
speaker.
Pins 2 and 3 are the “+” and “-” inputs of the speaker, and they are
looped inside the speaker to pins 1 and 4 (Pin 1 connects to Pin 2,
and Pin 3 connects to Pin 4.) Pins 1 and 4 are designed as loop-
through connections to successive speakers.
Parallel wiring
The advantage of this wiring scheme is that when the connector is
pulled out of an individual speaker, the following speakers will remain
connected. This wiring scheme is useful when troubleshooting
because you can disconnect one speaker at a time from the system
without disabling successive speakers. In this scheme pins 1 and 4
have no wires in them.
1. Insert both “+” wires into pin 2 (one wire from the amplifier or the
previous speaker; the other wire to the positive terminal of the
next speaker.)
2. Insert both “-” wires into pin 3 (one wire from the amplifier or
previous speaker; the other wire to the negative terminal of the
next speaker.)
3. Make sure both screw-down terminals are securely tightened.
Note: Because there are two wires connecting to each terminal, it
is important to make sure that the proper contact has been made
and that both wires are securely connected with the screw-down
terminal.
4. Tighten the empty screw-down terminals of pins 1 and 4 to avoid
unwanted vibration.
Loop-through wiring
In this scheme, the subsequent speakers are connected via pins 1 “+”
& 4 “-“. When one speaker is disconnected, all successive speakers
are disconnected too. This scheme can be advantageous when using
larger gauge wiring, and when required by local building code. An
entire section of speakers can be isolated while not affecting the
wiring.
1. Insert the “+” and “-” wires from the amplifier or previous speaker
into the 2 “+” and 3 “-” pins respectively.
2. Insert wires into pin 1 “+” and pin 4 “-” and connect them to the
next speaker’s pin 2 “+” and pin 3 “-” respectively.
3. Make sure all screw-down terminals are securely tightened.
Attaching and securing the wiring to the speaker
CSP-162
1. Using a slotted screwdriver, remove the horizontal
screw of the strain-relief fitting closest to the
cover plate door.
2. Loosen the hold-down screws of the sliding
pieces of the strain-relief fitting with a Phillips
head screwdriver.
3. Run the wires through the opening
of the fitting and plug the removable
locking connector into the connector
socket in the speaker.
Warning: DO NOT FORCE THE
CONNECTOR INTO THE SOCKET.
4. Replace the horizontal screw that
was removed.
5. Tighten the strain relief fitting by
gradually tightening both of the
horizontal screws.
6. Once the speaker cable is securely
clamped into place, tighten the two
hold-down screws.
Caution: If using plenum cable, do not
over tighten the strain relief fitting. It
can strip the cable and cause damage.
7. Once the wires have been installed
and are securely clamped, close the
cover plate door and secure it by
tightening the screw with a Phillips
head screwdriver.
CSP-142
1. Plug the removable locking connector with the connected
speaker wires into the connector socket in the speaker.
Warning: DO NOT FORCE THE CONNECTOR INTO THE SOCKET.
2. Replace the cover by replacing the two screws attaching it to the
backcan.
Important: Make sure all wiring conforms to local building codes.

Installing the speaker into the ceiling
Before installing the speaker into the ceiling,
it is recommended to attach a safety line
to the secondary support tab. Consult
local codes for more information
about secondary support
requirements.
1. Remove the grille by inserting the
included grille removal key in any
hole at the edge of the grille and pull
out to lift the grille.
2. Insert the speaker into the ceiling until
the rim is flush with the ceiling. Make sure to
tuck any excess wire into the ceiling behind the
speaker.
3. While supporting the speaker from below,
use a Phillips head screwdriver to tighten the
mounting tabs by turning the attachment
screws CLOCKWISE.
Note: The first quarter rotation turns the
mounting tabs outward. Make sure that all
the mounting tabs have turned out before
tightening all the attachment screws.
Caution: DO NOT OVER TIGHTEN. Over tightening can weaken
or damage the ceiling tile or ceiling structure and damage the
mounting tabs.
Adjust the Multi-Tap Selector
Before attaching the grille, set the multi-tap selector dial to the
appropriate setting. Delay attaching the grilles until the taps for all
speakers in the system are adjusted.
The multiple taps of the CSP series allow the flexibility of
determining how much power each speaker drives. For low-ohm
systems, set the dial to the “16R” position.
Caution: DO NOT CONNECT THE SPEAKER TO A HIGH-
VOLTAGE SYSTEM WHEN THE TAP IS SET ON BYPASS 16 OHMS
(16R SETTING ON THE TAP SELECTOR). DOING SO WILL
DAMAGE THE SPEAKER.

Attaching the Grille
1. Place the grille over the speaker baffle.
2. Press the edge of the grille into place
until it is level with the rim.
Note: Pressing on the center can dent
the grille.
Caution: Make sure the grill is firmly seated into the speaker to
prevent it from vibrating or falling.
Painting
Preparing
Remove the grille by inserting the included grille removal key in
any hole at the edge of the grille and pull out to lift the grille. Clean
off any oily residue by rubbing the surfaces with a cloth dampened
with a mild solvent (like mineral spirits) and wait until dry. Do not
use a wire brush, sandpaper, harsh detergents, chemicals, or strong
solvents to prepare these surfaces. It can cause permanent damage
to the grille and rim.
Painting the rim
Apply at least two coats of either latex or oil-based paint to the rim.
For best results apply a coat of oil-based primer first.
Painting the grille
Spray on at least two thin coats of latex or oil-based paint. Applying
the paint to the grille with a brush or roller is not advised because it
can create clogs in the mesh and diminish the sound quality of the
speaker. After the paint has dried, replace the grille.
Caution: When painting the speaker after it is installed, make sure to
cover the speaker baffle. Do not attempt to paint the interior of the
speaker. It could cause permanent damage.
