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, 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.

You will need to remove the grille in order to access the toggle

clamp screws. To remove the grille from the speaker, pull at the

grille's edge. A tool is supplied that can

be inserted through a perforation at

the grille's edge. Pull the grille outward

after insertion of the tool.

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.

Phillips screws

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 the speaker frames are to be painted, either before or after

installation, use the paint-mask (the inner cardboard disc) to cover

the speaker driver(s) to prevent damage. DO NOT PAINT THE GRILLE

AND FRAME ASSEMBLY TOGETHER. The grille should be painted

separately. The grilles can be painted using multiple light coats

of paint. Certain paints will require thinning to avoid clogging

the grille's perforations. It is not necessary or recommended to

remove the scrim cloth from the back of the grille prior to painting.

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!

After testing the operation of the speakers press the grille into the

slot of the frame and enjoy!
