Series
and
Parallel
Speaker
Connections
Whenever
connecting
more
than
one
speaker
per
channel
to
an
amplifier,
you
must
consider
the
way
in
which
the
amplifier
will
be
impacted
by
adding
the
additional
speaker(s).
Additionally,
speakers
with
dual
voice
coils
also
apply
to
this
consideration.
Two
voice
coils
in
a
single
speaker
also
cause
different
reactions
from
an
amplifier
depending
on
the
way
in
which
they
connect
to
the
amplifier.
The
connection
of
more
than
one
speaker
per
channel
will
make
the
amplifier
run
warmer.
For
the
best
sonic
results,
use
one
speaker
per
amplifier
channel.
If
you
must
connect
more
than
one
speaker
per
channel,
there
are
two
methods
in
which
to
do
so:
Series
and
Parallel.
Series
Connection
A
series
connection
is
established
when
voice
coils
are
connected
in
a
string
–
end
to
end
–
so
there’s
only
one
way
for
audio
signals
to
flow
“in”
and
only
one
way
for
audio
signals
to
flow
“out”.
For
example,
if
you
were
to
series
‐
connect
two
speakers
to
the
front
right
channel
of
the
amplifier:
•
The
positive
output
terminal
of
the
right
channel
connects
to
the
positive
input
post
of
the
first
speaker.
•
The
negative
input
post
of
the
first
speaker
connects
to
the
positive
input
post
of
the
second
speaker.
•
The
negative
input
post
of
the
second
speaker
connects
to
the
speaker's
negative
output
terminal
of
the
right
channel.
The
total
impedance
of
speakers
in
series
is
found
by
adding
their
impedances
together.
For
example;
two,
four
‐
ohm
speakers
in
series
is
an
eight
‐
ohm
load.
Series
connections
are
easier
on
the
amplifier
than
parallel
connections
as
the
total
impedance
is
higher
than
driving
a
single
speaker.
An
example
of
a
SERIES
connection
between
two
speakers.
