two. Speaker Connections
Speakers and electronics ter-
minals have corresponding (+)
and (–) terminals. It is impor-
tant to connect both speakers
identically: (+) on the speaker
to (+) on the amplifier and (–)
on the speaker to (–) on the
amplifier. Wiring “out of phase”
results in thin sound, weak bass
and a poor stereo image.

The wires for both speakers
should be the same length. If
one speaker is placed closer to
the amplifier than the other,
hide the excess wire behind
the wall.
The FM8SUB has two speaker
connections. Connect one set of
terminals, along with your left
satellite to the left channel of
your amplifier. Connect the
other set of terminals, along
with your right satellite to the
right channel of your amplifier.

Painting the Speaker Frame and Grille
FM Series loudspeakers can be
painted to match any style of
decor. If you wish to change
their color, the satin finish on
the grille and frame will func-
tion as a primer coat. Before
painting install the paint guard
(in the assembly kit) securely
into the recess in the baffle.
This will protect the speaker
components and baffle from
paint residue.
Use a high-quality spray paint,
and apply a thin coat of color.
Be certain the grille perfora-
tions remain free of paint.
Filling them with paint will
diminish the sound quality.
Note: Gently remove the
acoustical blanket from the
back of the grille before paint-
ing. Reattach the acoustical
blanket after the paint has
dried.
FM Series Owner’s Manual 7/22/98 9:27 AM Page 9
If there is no sound from
either of the speakers, check
the following:
• Receiver/amplifier is on and a
source is playing.
• Check all wires and connec-
tions between receiver/amplifier,
in-wall room volume control and
speakers. Make sure all wires are
connected. Make sure none of
the speaker wires are frayed, cut,
or punctured.
• Review proper operation of
your receiver/amplifier.
If there is no sound coming
from one speaker, check the
following:
• Check the “Balance” control on
your receiver/amplifier.
• Check all wires and connec-
tions between receiver/amplifier,
and speakers. Make sure all wires
are connected. Make sure none
of the speaker wires are frayed,
cut, or punctured.
If there is low bass output,
check the following:
• Make sure the connections to
the left and right “Speaker
Inputs” have the correct polarity
(+ and –).
If the system plays at low vol-
umes but shuts off as volume is
increased, check the following:
• Check all wires and connec-
tions between receiver/amplifier
and speakers. Make sure all wires
are connected. Make sure none
of the speaker wires are frayed,
cut, or punctured.
• If more than one pair of main
speakers is being used, check the
minimum impedance require-
ments of your receiver/amplifier.
