CSP-SERIES
USER’S GUIDE
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 multitap 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" titaniumcoated 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.

Precautions
▪ Please read and follow these
instructions, and keep this
manual in a safe place.
▪ 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.
▪ Use only the correct,
recommended voltage.
▪ Do not attempt to disassemble
or repair this product. Repairs
should only be done at an
authorized repair shop.
▪ Keep this product away from
water, moisture, and any
flammable gases or liquids.
▪ Handle this product with care.
▪ Clean this product with a soft
dry cloth.

Overview/Precautions
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
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.
▪ 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.
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.
