Dayton Audio CS420EC 4" 2-Way Enclosed Ceiling Speaker - Manual (Page 2)

duce the chance of breaking the plaster. Test fit the speaker in
the hole, the speaker should fit loosely and the speaker frame
should cover the edges of the hole. Repeat these steps for the
other speaker.
5) Speaker Cable
Don’t compromise sound quality by using thin, inexpensive
speaker wire, we recommend using a high quality oxygen free
copper speaker cable. For runs less than 50 feet we recom-
mend 16 gauge cable, and for longer runs we recommend
14 gauge or larger cable. For installations with in-room stereo
volume controls we recommend using a four conductor speaker
wire from receiver to volume controls. Most municipalities require
the use of CL2 rated speaker cable for installation in walls and
ceilings. Leave enough speaker cable so you can stand comfort-
ably on the floor or ladder while connecting the speaker cable to
the speakers.
6) Speaker Connection
Remove about 8" of the cable jacket to expose the inner conduc-
tors. Strip 1/4" of insulation from each conductor and connect to
the speaker terminals. When connecting the wires to the speak-
ers, be sure to observe proper polarity. Most CL2 rated speaker
cable will have red and black conductors so you will connect the
red wire to the red speaker terminal and the black wire to the
black speaker terminal.
For high impedance (70 V) applications set the rotary switch to
the wattage to be used. For Low Impedance (8 ohm) applications
set the rotary switch to the 8 ohm position.
Note: To avoid damage to the speaker, be sure to switch off
the amplifier power when changing the input.
7) Final Installation
To install the speakers into the ceiling, remove the grills,
this will give you access to the mounting screws. Turn
the mounting clamps so they are positioned as in the il-
lustration, this will allow the speakers to clear the hole for
installation. Insert the speaker into the hole, and tighten the
mounting screws. As you turn each screw, the mounting
clamps will rotate outward to engage ceiling material.
CAUTION: Do Not Over-Tighten the Clamps. Too much torque may snap off the lug and the
speaker will not seat securely. A snug fit is all that is necessary to assure proper performance.
8) Painting Speakers
If you choose to paint the speaker grill and/or frame we have provided a “Paint Masking Tem-
plate” to cover the woofer/tweeter assembly and help prevent possible damage.
Do not try to
paint the frame and grill assembly together, the grill should always be painted separately.
Do not apply heavy coats of paint that might block the perforations in the grill.
9) Troubleshooting
Should your speakers not work properly, check the following:
No sound from speakers:
●
Most stereo receivers have an A/B speaker selector switch. Make certain that
this switch is in the proper position.
● Mute feature is activated.
One speaker is playing while the other is not:
● Check the balance control on the receiver. Make sure it is centered.
● Loose connection at either the receiver or the speaker. Double check connections.
● Bad speaker cable. Replace suspect speaker cable.

3) Speaker Location
To achieve the best performance from your Dayton Audio speakers, it is important to carefully
select the location for installation. Your ceiling speakers should be installed 5 to 8 feet apart to
ensure proper stereo imaging. Mount each speaker the same distance from the intersecting
walls to maintain a uniform look. Keep the speakers at least 2 feet away from the corners of
the room to avoid overemphasized bass reproduction.
4) Speaker Installation
Once you have selected the location for your speakers, you are ready to install them.
CAUTION: Be certain that there are no electrical wires, water pipes, or heating ducts
in the planned installation area before you start drilling or cutting into the ceiling. If
there is an electrical outlet nearby, turn off the circuit breaker to avoid possible injury.
Ceiling speakers are designed to be mounted in the ceiling between the joists or trusses.
Once you have selected the location, check to be sure you are between the joists or truss.
One method is to tap on the ceiling, you will hear a hollow sound when between two joists or
trusses and a sharper, more solid sound when right on top of, or close to a joist or truss.
An easier, more accurate method for finding the location of joists or trusses is to use a
stud finder.
The Contractor Series Ceiling speakers include a two-part template. Remove the center circle
from the template, this is a paint masking template to use if you choose to paint the speaker
frames and grill. The outer ring is used to mark the cut-out for the speakers.
Once you have established that your chosen location is between two joists or trusses, and
that there are no obstructions in the ceiling, tape your speaker template to the ceiling and
lightly trace around the inside edge with a pencil and drill a 1" hole in the center of the
template outline. Next, use a piece of stiff wire (a coat hanger works well), bend it 8" from the
end at a 90 degree angle. Insert the bent part of the coat hanger into the 1" hole and rotate
the wire in a complete circle to check for obstructions. If the wire hits a stud on either side,
reposition your template to the left or right and mark the outline again. Keep the pilot hole
within the template outline.
If the ceiling is made of drywall, simply cut the marked area with your utility knife or drywall
saw. If the ceiling is made of plaster, you should use a saw with a higher tooth count to re-
