Tape Measure, Pencil, Ladder, Drywall Saw, Stud-Finder, etc.
GENERAL DESCRIPTION
These two-way speakers have specially designed woofers
with linear long throw butyl rubber surrounds for long life and
superior damping. Dome tweeters are utilized for excellent
high frequency dispersion throughout your entire listening
environment.
SHIPPING DAMAGE
Each speaker is thoroughly tested before it leaves the factory.
However, in shipment, accidents may occur. Please inspect your
speakers carefully when you receive them to make sure there
is no damage. If there is, please notify your dealer or supplier
immediately for assistance. If you received your speakers by
public transportation, report the damage immediately to the
shipping company.
AMPLIFIER OPERATION
These speakers will perform well with ampliers from 5 to
125 Watts RMS. However, damage to the speakers can be
done by ampliers of nearly any power rating if the amplier is
overdriven into clipping. “Amplier clipping” is a phrase used
to describe a condition when, because of the volume demand,
an amplier is being asked for more power than it can give.
Clipping causes distortion of the audio signal. If you should
hear an unusual amount of distortion at high listening
levels then consider reducing the volume. DAMAGE DONE
TO A SPEAKER BY CLIPPING IS NOT COVERED UNDER THE
WARRANTY.

SPEAKER PLACEMENT
Placement of in-ceiling and in-wall speakers should be carefully
considered. Please contact a professional for assistance if you
are uncomfortable with the planning or installation process.
Ideally, the speakers should be located where they will provide
the best possible sound and ease of installation. It is beyond
the scope of this publication to discuss all of the various
aspects of speaker placement, but here are some helpful
suggestions.
For the front channels of a home theater we recommend that
the speakers be placed between 18 and 36 inches (0.45m to
0.9m) from an adjacent wall/surface, as measured to the center
of the hole. Avoid placing the speakers less than 12 inches
(0.3m) from an adjacent wall. When placing speakers near a
corner, avoid locating them an equal distance from the two
adjacent surfaces.
If the drywall has not yet been installed, rough-in-kits are
available to reserve the speaker location. The hole is then cut
when the drywall is installed.
WIRING
To achieve maximum performance we recommend that the
speaker cable be at least 16 gauge or larger for runs over 50 feet
(15m) and that the cable be double insulated. A CL-2 or CL-3
rated cable may be required. Check local codes. “Zip cord,”
which is single insulated and is often made with clear insulation,
should be avoided as it is not as durable. Allow about 2½ feet
(0.8m) of free cable at the speaker cut-out and sufcient length
at the other end to reach the electronics. Having to add extra
cable later can be tedious and time consuming.
Avoid bundling speaker cables parallel to electrical cables
for extended lengths. Though the impedance is low and the
likelihood of interference low, this may help reduce hum and RF
interference. When securing the cable, use care not to staple or
nail through the electrical conductors. Doing so could result in a
short that might damage the electronics.
When connecting your speakers, make sure proper polarity
(phasing) is maintained. Simply put, this means ensuring the
same wire which is connected to the positive terminal of the
amplier has its other end connected to the positive terminal of
the speaker. It is important to check this on all speakers. If the
connections on one of the speakers are reversed, (out of phase)
the sound quality will be impaired.
INSTALLATION
If the speaker locations have not yet been established then do

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, ashlight, etc.). Use an “electronic stud nder”
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 ush t.
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 brous material, such as berglass,
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 berglass 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
specically 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
berglass.
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 ts 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 t 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 signicant 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.
