OWNER’S MANUAL

CSS6 DT Zero

In-Ceiling Loudspeaker

INTRODUCTION

Congratulations on your purchase of SpeakerCraft CSS6 DT Zero speaker. Since aesthetics are such a large part of the appeal
of flush-mount loudspeakers. The CSS6 DT Zero will offer yet another appearance option. The CSS6 DT features a 6

1

⁄2" woofer
and dual 1" resin coated silk-dome tweeters. The CSS6 DT Zero also offers pivoting tweeters, allowing the installer to focus
directional high frequencies toward the listening area. This is critical in situations where a less than favorable installation loca­tion is unavoidable.

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.

When placing your speaker into the ceiling, it should ideally be located above the primary listening area. The CSS6 DT Zero
is intended to be used as a single stereo speaker in small listening environments, walk-in closets, laundry rooms, bath rooms
etc. In a large area, it may be necessary to place additional speakers throughout the room to get the optimal effect.

MOUNTING SURFACE PREPARATION

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.

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 electrical

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 a paint mask insert 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 Figure 1) 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 of 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

SPEAKER INSTALLATION

The unique integral four foot mounting system incorporated into each CSS6 DT Zero
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 (observing 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 Figure 2), thereby clamping the drywall
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.

SPEAKER ADJUSTMENTS

Your CSS6 DT Zero speaker 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.

PAINTING THE SPEAKERS

Figure 3

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”. 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,
however, great care should be taken not to clog the holes, as this will greatly reduce the sound quality of the speakers.
SpeakerCraft recommends 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(ASM90509)
The metal enclosures mount easily between joists.
