so now. If possible, assess the area behind the ceiling for possible
concealed obstructions such as wiring, heating ducts, cross-bracing
etc. Absence of a crawl space will require greater study of observable
clues and may also require the use of inspection holes and inspection
tools (camera, mirror, flashlight, etc.). Use an “electronic stud finder”
to locate the positions of the joists or studs. We recommend that the
edge of the speaker holes be at least 3/4" (19mm) away from joists or
studs whenever possible to allow clearance for the toggle clamps.
Once the speaker locations are established use the cardboard
template or the plastic compass provided with your speaker to draw
the speaker cut-out. The hole diameters for the various speakers are
marked on the compass. The cardboard templates may also be used
as a visual aid for placement of the speakers. To do this, temporarily
hold the templates in place with a push tack or tape.
Using the proper tool cut the appropriate sized
hole in the ceiling. On drywall, clean cuts can be
made with a drywall saw. Make sure to clean the
excess debris from the front face of the hole to
ensure a flush fit.
If the cable has not yet been run, do so now that you have better
access to the ceiling. Once the speaker cable has been run, pull the
end of the cable out of the speaker cut-out, strip back a section of the
jacket as needed, and then expose ½" (13mm) of each conductor.
To aid in speaker performance, a fibrous material, such as fiberglass,
may be placed behind the speaker. This may also help to reduce
unwanted sound from being transmitted into adjoining rooms. If the
ceiling space has blown or loose insulation, care must be taken to
prevent the loose insulation from entering the back of the speaker.
This can be accomplished by placing a batt of fiberglass insulation,
fabric barrier, or bag over the back of
the speaker. Alternatively you may
use an
Insu-Flate ISF-147,
which is an
acoustically transparent fabric cover
specifically designed for this application.
Placing a rigid enclosure behind the
speakers can be done but the enclosure
should be large enough not to degrade
the performance of the speaker. Rigid enclosures of less than 0.75
cu ft (21 liters) should be stuffed with acoustic insulation such as
fiberglass.
As the drawing shows, the speakers utilize
Toggle Clamps which, after tightening, hold
the speakers in place. Ensure that the
toggle clamps are rotated into their “Home”
position prior to installation.
Verify that the speaker fits properly into the
cut-out and then remove the speaker from
the hole.
Connect the wire conductors to the terminals on the back of the
speaker by depressing each spring terminal, inserting the wire into
the hole, and releasing the terminal. Use care to observe the proper
polarity (+ & -). Speakers wired out of phase will exhibit an apparent
loss of bass response.
Note:
Single-Point speakers
have both the left and right channel
connections on the same speaker. Ensure that both channels are
connected and in phase. An out of phase connection to a single-point
speaker will be immediately obvious when signal is applied since
there will be little if any bass output. If disconnecting one of the
inputs increases the bass output then the inputs are out of phase.
Insert the speaker into the hole and tighten the four toggle screws.
As you start to turn each screw the toggle clamps will rotate outward
to engage the ceiling or wall material as shown. CAUTION: DO NOT
OVER-TIGHTEN THE CLAMPS. Too much torque may damage the
toggle, causing the speaker not to seat securely. A snug fit is all that
is necessary to assure proper performance.
If your speaker includes a pivoting tweeter aiming it toward the
listening area will raise the amplitude of the highest frequencies
(>12kHz), adding brilliance. USE CARE TO AVOID DAMAGING THE
DOME OF THE TWEETER WHEN AIMING!
Attach the grilles to the speakers and enjoy. Should you wish
to remove the grilles from the speakers pull at the grilles' edge.
Initially there will be a significant resistance because the grilles are
magnetically attached.
The grilles can be painted using multiple light coats of spray paint.
Custom color spray paints are available from specialty companies.
Contact your dealer for more information. The grilles should be
removed from the speaker and painted in a clean environment to
prevent contamination. It is best to go around the grilles and apply the
paint from multiple angles. DO NOT remove the scrim cloth from the
backside of the grille. It is not replaceable.
