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
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”.
Painting the Aluminum Grilles
The grille is important to the sound of the
CS loudspeakers. Do not fill the holes of
the grille with paint. The grille is construct-
ed of aluminum with a perfectly even
powder coat overall. This powder coat is
an ideal primer.
Remove the grilles before painting. If you are
using spray paint, use two thin coats without
any primer. If you are using a compressor and
a spray gun, use the finest, most diffuse
setting. Practice first on some paper if you
have no experience painting with spray paint.
If you are using an applicator or brush, and
a can of paint, thin the paint first. You do
not want to have to poke hundreds of holes
in your beautifully painted grilles.
