SPEAKER PLACEMENT
Before installing your speakers, you should consider the placement
carefully, taking into account the location of electrical, plumbing
and other fixtures. Contact your dealer for assistance if you are not
sure of the best location in your particular room environment.
Placement In Ceiling: When placing your speakers in the ceiling,
they should ideally be located above the primary listening area.
The unique tweeter baffle of the CSS6 Series speakers allows for
more forward radiation and a more even frequency response than
is obtainable on conventional coaxial type round speakers.
(See Diagram 1) If the speakers are positioned far away from the
primary listening area, adjust the pivoting tweeter so they are pointed at the primary listening area.
Note: To avoid
possible damage to the pivoting tweeters, read the section entitled “SPEAKER ADJUSTMENTS” in this manual prior to
performing the tweeter adjustment.
In a very large room with low ceilings, it may be necessary to place additional speakers throughout the room.
Contact your Authorized SpeakerCraft dealer for assistance.
MOUNTING SURFACE PREPARATION
New Construction - Unfinished Ceilings
A New Construction Bracket (available from your dealer), may be installed prior to drywall application across joists (up to
24" on-center) where a speaker will be located. Insulation material should be in place prior to installing drywall. After the
hole is cut and the drywall is installed, the speakers are then easily installed following the instructions for mounting in
“Finished Ceilings”. Note: If the speakers are to be mounted more than 24" on-center, a special “Extra Long Wing”,
available from your dealer will be required.
Finished Ceilings
Prior to the actual installation of the speakers, it will be necessary to run cables to the speaker locations. See your dealer
for more information about cable installation. After the cable has been properly installed, you are ready to mount the
speakers. Following the simple steps listed below will result in a professional looking installation:
1. Determine the best area to mount your speakers. This area of the ceiling should be free of obstructions such as electri-
cal conduit, HVAC ducts, or water lines. This can best be determined by noting the placement of fixtures and gaining
access to an attic or crawl space for further analysis of the location of such obstacles.
2. Find the joists nearest the desired speaker mounting location. We highly recommend using a good stud-finder tool
for this procedure. If you are lining up the speakers to some other object or molding in the room, make sure you
consider the size of the baffle flange which extends beyond the mounting hole.
3. Mark the hole. A template for setting the hole is provided in the box (along with two paint mask inserts for use when
painting). Position the template in the desired position and pencil an outline on the ceiling.

4. Cutting the hole. CAUTION:This is the most important part of the entire
installation. If you are uncertain whether any obstructions exist behind the
desired mounting area, you should start by cutting a small hole in the center
of your penciled mounting hole with a drywall saw, cutting at a 45º angle
towards the inside of the hole. (See Diagram 2) Cutting the small hole at this
angle will make drywall repair much easier, using the piece cut out. Once you
have determined that there aren’t any obstructions in your desired mounting
location, start cutting the finished hole at a 90º angle to the ceiling surface.
5. Add insulation. If the area in the ceiling is not already insulated, add an
adequate amount insulation material to loosely cover the back of the speaker.
If the insulation material used is faced with foil or paper, position the foil or
paper away from the speaker.
SPEAKER ADJUSTMENTS
Your CSS6 Series speakers come from the factory with the tweeter facing straight
out from the baffle. This will result in the overall smoothest response. However,
depending on your particular primary area, room acoustics, ceiling height, or
personal preference, you may find the sound more pleasing by pointing the
tweeters in a particular direction. If additional treble is desired in the primary
listening area, point the tweeter towards that area; and if less treble is required,
point the tweeter away. Push gently at the edge of the tweeter to point it in the
desired direction. (See Diagram 3) CAUTION: Avoid touching tweeter dome as
damage WILL occur on metal dome tweeters (CSS6 ONE & THREE).
Tweeter Adjustment (CSS6 THREE):
The switch labeled TREBLE allows for 6dB of tweeter adjustment. Your speakers were shipped with
the treble switch in the neutral position, providing the most linear frequency response. If you desire
more treble, roll the switch to the “+” position, and the tweeter will play 3dB higher. If you want less
treble, roll the switch to the “–” position and the tweeter will play 3dB lower. To return to the neutral
setting, slide the switch to the middle position. (See Diagram 4)
Woofer Adjustment (CSS6 THREE):
The switch labeled BASS allows for 6dB of bass adjustment. Your speakers were shipped with the bass
set to neutral, resulting in 6
Ω of impedance. This setting provides the flattest bass frequency response.
If you desire more bass, roll the switch towards “+” and the bass will play 3dB higher and lower the
impedance to 4
Ω. If you want less bass, roll the switch towards “–” and the bass will play 3dB lower
and increase the impedance to 8
Ω. This setting provides a more linear bass frequency response. To
return to the neutral setting, slide the switch to the middle position. (See Diagram 5) Remember that
altering the impedance affects the number of speakers able to be driven by an amplifier. If multiple
pairs of speakers are to be driven by one amplifier, SpeakerCraft suggests using the lowest output
position (switch rolled towards the “–” position) until it is determined that the amplifier will operate
properly with the speakers switched to a higher output mode. If you want to safely operate multiple
pairs of speakers, consider purchasing SpeakerCraft S4 or S8 Speaker Selectors.
SPEAKER INSTALLATION
The unique integral four foot mounting system incorporated into each CSS6 Series speaker allows
for a quick installation by following these easy steps:
1. Remove the grille. It may be necessary to push one or two of the mounting screws and its
attached foot towards the baffle and against the inside surface of the grille to force the grille out
of its retaining groove.
2. Attach the speaker cable (obser ving the proper polarity with your amplifier, + to + and – to –).
Make sure the left channel of the amplifier is connected to the left speaker, and the right channel is
connected to the right speaker.
3. Make sure the mounting feet are turned inward to clear the opening, and insert the speaker into the
ceiling. Position the speaker into the hole.
Note: The flange of the speaker is designed to flex and
conform to any small imperfections in the ceiling’s surface. Tighten the four screws on the front of the
baffle only enough to make the flange become snug against the ceiling. As you tighten the screws,
the feet will automatically flip into an outward position (See Diagram 4), thereby clamping the dry
-
wall between the feet and the flange. CAUTION: Over tightening may warp the baffle, crack the
ceiling, cause flange to distort, and make the grille difficult to install.
4. Push the grille firmly into the slot in the speaker baffle.
PAINTING THE SPEAKERS
If you plan to paint your speakers, we recommend that it be done prior to installation. If you plan to
paint your speakers sometime in the future, it is best to remove them by simply reversing the steps for
“SPEAKER INSTALLATION” on page 2. If it is necessary to paint the speakers while they are still in the ceiling, the paint masks provided in
the carton must be installed in place of the grille while the flange is being painted with the ceiling. The grilles can also be painted, how
-
ever, great care should be taken not to clog the holes, as this will greatly reduce the sound quality of the speakers. SpeakerCraft recom
mends only light spray painting using 5 parts thinning agent to 1 part paint. Do not paint the grilles while they are attached to the speaker.
If it is necessary to paint the under grille material, follow the same procedure used to paint the grilles.
SPECIAL FIRE WALL INSTALLATION
If you plan to mount your speakers in a fire-rated ceiling, you should purchase SpeakerCraft CSS6 Sound Enclosures. The metal enclosures
mount easily between joists, and contain a standard electrical type connector for connections of your speaker cable directly to the speaker.
