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 wire so that at least
two inches of each conductor are free.
2. Strip one half inch of insulation from the
end of each conductor of the speaker
wire.
3. If you have gold pin connectors which
you wish to use, affix them to the
stripped wire ends now.
4. Connect one stripped wire end (or con-
nector) to the black and one to the red
terminal. Pay attention to the markings
on the wire. Each speaker must be con-
nected to the amplifier in the same way.
5. Place the speaker baffle in the frame and
secure it with the supplied #8 x 1/2”
screws. If you find that the baffle does
not smoothly fit the frame, slightly
loosen the mounting screws that hold
the frame to the bracket.
6. Carefully fit the grille into its recess so
that it is barely in place. Starting with one
corner, go around the speaker, pushing
the grille in a little bit each time. You
should be gentle, the aluminum grille
can be easily bent out of shape. The
speaker will have an absolutely flush
appearance when it is fully in place.
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 speakers.
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 togeth-
er or “in-phase”.
