frameless
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.
This speaker is optimized for off-axis listening through the use
of a pivoting tweeter and a 15 degree baffle tilt. We recommend
directing the woofer and tilting the tweeter toward the listening
position. USE
CARE TO AVOID
DAMAGING THE
DOME OF THE
TWEETER WHEN
AIMING!
Insert the speaker
into the hole and
turn each screw clockwise. The toggle clamps will rotate outward to
engage the ceiling material as shown. Before tightening the three
screws, orient the speaker toward the listening area. Tighten all
the screws. 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.
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.
