Congratulations on the purchase of your Dayton Audio Ultra
Speaker System. These speakers were manufactured with high quality components and engi-
neered to deliver top quality sound performance.
Please read through the instructions completely before you begin your installation.
1)
Parts Inventory
Your speaker kit should include the following:
1 pair of Dayton Audio Ultra
●
1 hole cut-out template
●
1 masking template for frame painting
●
2)
Installation Tools
The Dayton Audio speakers can be installed with the following simple tools:
Pencil
●
Masking tape
●
Drill & drill bits
●
Utility knife or wallboard saw*
●
#2 Phillips screwdriver
●
Wire cutters & wire stripper/crimp tool
●
Stud finder**
●
* Recommended for use if installing in plaster walls.
** Optional tools to make the installation easier.
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 corners (where the wall and
ceiling meet) to maintain a uniform look. Keep the speakers at least 2 feet away from the
corners of the room to avoid overemphasized bass reproduction.
Note: If installing the US622C or US822C Single Point Stereo Speaker, locate in
the center of the room.
Note 2: For installing the US650C LCRS Ceiling Speaker, rotate the speaker
housing so that the built-in 15 degree angled loudspeaker is pointed at the center of
the listening area. The location and position of the speaker mount can best be de-
termined by consulting the room layout and speaker setup guide that accompanied
your equipment. Once the US650C LCRS Ceiling Speaker is firmly mounted and in
place, adjust the speaker's center pivoting tweeter for best listening results.

Speaker Installation
Once you have selected the location for your speakers, you are now 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.
The ceiling speakers are designed to be mounted to the ceiling area between the
studs. Once you have selected your location, the next step is to be sure you are between
the studs. By tapping on the ceiling, you will hear a hollow sound when between two studs
and a sharper, more solid sound when right on top of, or close to a stud.
An easier, more accurate method for finding the location of wall studs is to use a
stud finder.
Once you have established that your chosen location is between two studs 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.
Drill a 1" hole in the center of the template outline. Next, using 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 re-do the light pencil outline. Keep the pilot hole
within the template outline.
If the ceiling is made of drywall, simply cut the marked
area with your utility knife. If your home has plaster walls,
then you will need to use a wallboard saw to cut the
speaker opening.
Check the speaker opening by placing one of the speak-
ers into the hole. The speaker should fit loosely into the hole.
Repeat these steps for the other speaker.
5)
Speaker Wire
Don't compromise sound quality by using thin, inexpensive
speaker wire. We recommend using a high quality oxygen free
copper wire. For runs of 10 to 50 feet, choose a 16 gauge wire.
A 14 gauge wire should be used for runs greater than 50 feet.
Note: If installing the US622C or US822C Single Point
Stereo Speaker, a 4 conductor speaker wire is needed.
6)
Speaker Hook Up
Split the two conductors of the speaker wire apart about
2-4 inches so that they form a "Y". Using wire strippers, remove
about 1/2" of insulation from each wire.
When hooking up the wires to the speakers, be sure to
observe proper polarity. Make certain you connect the positive
lead from the receiver to the "+" terminal on the speaker and the
negative lead from the receiver to the "-" terminal on the speaker.
7)
Final Installation
To install the speakers into the ceiling, first remove
the grills using a small paper clip. Turn the "Angle Lug
Installation Clamps (Item A)" so they are positioned as
in illustration on right. This way, they will clear the cut out
hole for installation.
Insert speaker assembly into hole, and begin to
tighten installation screws. As you start to turn each
screw, the "Angle Lug Clamps" will rotate outward to
engage ceiling material. ("C")
CAUTION: Do Not Overtighten the Clamps. Too much torque may snap off the
lug, causing the speaker not to seat securely. A snug fit is all that is necessary to
assure proper performance.
8)
Painting Speakers
If speaker frame is to painted, either before or after installation, use the "Paint Mask-
ing Template" to cover the woofer/tweeter assembly to prevent damage to them. Do not
try to paint the frame and grill assembly together. The grill should always be painted
separately. Do not put such a heavy coat of paint on the grill that the perforations are
blocked.
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.
