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 con-
nectors which you wish to
use, affix them to the
stripped wire ends now.
4. Connect one stripped
wire end (or connector) to the
black and one to the red terminal.
Pay attention to the markings on the
wire. Each speaker must be connected to
the amplifier in the same way.
5. Place the speaker baffle in the frame and
secure it with the supplied #8 x 3/4”
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 easi-
ly 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 speak-
ers 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
connections 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”.
