Installing the Speaker
If the grille is already

installed, remove it by

using a bent paper clip or

the tip of a corkscrew and

pulling it away from the

frame (See Figure 13).

1. Separate the speaker

end of the two-conduc-

tor speaker-wire run to

free at least 2” of each conductor.

2. Strip 1/2” of insulation from the end of

each conductor. (See Figure 1)

3. To connect the stripped end of one

conductor to the black terminal, push

down on the black terminal lever. Insert

the stripped end of the conductor into

the opening. Release the pressure on

the lever.

4. Repeat #3 with the other conductor and

the red terminal.

5. Connect the opposite ends of these con-

ductors to their respective amplifier ter-

minals. Pay attention to the markings

on the wire. If you are unsure which

conductor to insert into which terminal,

see the section titled “Speaker Phase” in

the owner’s manual.

6. Repeat these instructions

for each speaker you are

connecting to the ampli-

fier.

7. Place the speaker baffle

in the frame by inserting

the tabs at the base of the

speaker baffle into the cor-

responding holes in the

frame and pushing the speaker forward

until the snaps engage. (See Figure16)

8. IMPORTANT: When installing the

speakers in the ceiling, or if the instal-

lation is in an earthquake zone, it is rec-

ommended that you utilize the enclosed

sheet metal screws to secure the baffle

to the frame.

a. Locate the dimples on the front baffle.

b. Place the self-tapping sheet metal screw

in the dimple and turn it with a screw

driver until it cuts through the baffle

and anchors securely in the frame.

Speaker Phase
Speaker wire has two conductors. One

conductor is attached to the negative (-)

terminals and one conductor is attached

to the positive (+) terminals of both your

speaker and your amplifier. Usually, the

wire is marked for your convenience.

There are different ways wires are marked:

a stripe on one wire, a ribbed area of one

conductor you can only feel, different col-

ors of metal wire on each conductor, or

there might be a fabric strand or string

wound into one of the conductors. Of

course, there are some wires which appear

completely identical. Be careful, or you

might make a mistake.
If you make a mistake, one speaker will

be playing “out-of-phase” with the other

speaker. An out-of-phase pair of speakers

work against each other and the sound of

the two speakers playing together will be

lacking in bass and be “phasey” sounding.

If you suspect the sound is not right and

you cannot see any markings on the wire,

try this simple test:

1. Stand half way between the two speak-

ers.
2. Play some music with the amplifier or

radio set to Mono.

3. Listen to the richness of the bass and the

loudness of the sound.

4. Turn off the amplifier and reverse the con-

nections on one amplifier channel only.

5. Repeat the listening test with the same

setting of the volume control. When the

sound has a richer bass and is slightly

louder the speakers are working together

or “in-phase”.

Adjusting the Bass and Treble
Controls
The PR Performance loudspeakers feature

separate baffle-mounted bass and treble

controls for fine tuning after installation.

Each control provides for approximately

3dB in steps of 1dB of Bass or Treble

reduction. This is useful if the speakers

are placed near boundaries (Bass Cut)

or in a room with highly reflective sur-

faces like glass or tile. (Treble Cut). (See
Figure 18)
