NOTE:
The
port
shown
can
be
placed
on
any
face
of
the
enclosure
as
long
as
the
port
ends
are
not
obstructed
.
NOTE:
When
using
vented
enclosures,
for
maximum
reliability
and
power
han-
dling
ensure,
that
a
subsonic
or
"infrasonic"
filter
at
or
above
27Hz
is
used
so
that
only
usable
low
frequency
signals
are
sent
to
the
subwoofer.
Enclosures
Wiring
Configurations
By
varying
the
wiring
configuration
of
your
speakers
you
can
create
an
impedance
load
to
match
your
system.
Altering
the
wiring
configurations
gives
a
range
of
options
for
impedance
loads.
Series
,
Parallel
,
or
Series-Parallel
wiring
configura-
tions
are
different
techniques
for
wiring
speakers
that
provide
different
loads
.
Se-
ries
configuration
is
a
string
method
where
speakers
are
wired
end
to
end.
Parallel
configuration
uses
two
or
more
speakers
wired
across
common
terminals.
Series-
Parallel
configuration
combines
both
techniques.
Choose
the
wiring
diagram
that
corresponds
to
the
number
of
woofers
and
the
impedance
of
your
amplifier.

Subwoofer
Crossovers
There
are
two
operational
types
of
crossovers,
passive
and
active
.
Passive
cross-
overs
(coils
or
inductors)
are
placed
on
the
speaker
leads
between
the
amplifier
and
speaker.
An
active
crossover
is
an
electronic
filter
that
separates
the
audio
signal
fed
to
different
amplifiers
.
For
optimum
subwoofer
performance,
we
recom-
mend
using
an
active
80-1
OOHz
low-pass
crossover
at
12dB/octave.
