the same wire which is hooked to the positive terminal of the

amplifier has its other end hooked 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 quality of your bass will be seriously impaired.

INSTALLATION

If the speaker locations have not yet been established then do

so now. Assess the ceiling or wall area for possible concealed

obstructions such as wiring, plumbing, heating ducts, etc. For

the ceiling this is best done through an attic crawl space if

available. Absence of a crawl space will require greater study of

observable clues and may possibly require the use of inspection

holes and inspection tools (camera, mirror, flashlight, etc.). Use

a "stud finder" to locate the positions of the joists or studs. We

recommend that the edge of the speaker holes be at least ¾"

(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 (the outside of the inner cardboard disk) 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. Temporarily hold the templates

in place with a push tack or tape.

Using the proper tool, cut the appropriate

sized hole in the wall. On drywall, clean cuts

can be made with a drywall saw. Cut the

hole to the inside of the drawn circle.

If the cable has not yet been run, do so now

that you have access to the ceiling or wall's

interior. 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 or polyester fiber, 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, it is important to prevent the 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

cuft (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. This way, they will

clear the edge of the cut-out.

Verify that the speaker fits properly into the cut-out. If the hole

should have been cut a little too large the flange on the speaker

should cover this. 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.

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.

Phillips screws

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.
