Enclosures
This
manual
outlines
two
specific
types
of
enclosures
that
provide
distinctly
dif-
ferent
performance.
This
section
is
to
help
you
dec
i
de
which
type
is
best
for
your
application.
Sealed
Enclosures
Sealed
enclosures
are
the
simplest
to
build.
The
most
important
part
of
building
a
sealed
e
nclosure
is
to
make
sure
that
the
enclosure
is
airtight.
Using
glue
and
some
type
of
sea
lant
on
all
seams
will
ensure
solid
construction
and
prev
en
t
air
leaks.
The
box
volume
will
directly
impact
the
performance
of
the
speaker
Larger
enclosures
will
provide
flatter
response
and
deeper
bass
where
smaller
boxes
will
provide
a
bump
in
the
response
curve
and
generally
higher
output
for
greate
r
SPL
Advantages
of
sealed
enclosures:
•
Small
enclosures
•
Lin
ear
(Flat)
response
•
No
port
noise
•
High
power
handling
at
all
frequencies
•
Excellent
for
sound
quality
•
Extended
low
frequency
output
when
compared
to
vented
enclosures
Vented
Enclosures
Vented
enclosures
vary
only
from
the
sea
led
enclosure
in
that
a
vent
or
por
t is
added
to
"tune"
the
enclosure.
The
enclosures
recommended
are
designed
for
great
overall
performance.
Larger
boxes
tend
to
be
easy
to
tun
e
to
lower
frequen
-
cies
while
medium
and
small
boxes
are
easier
to
tune
to
higher
frequencies
.
The
vented
design
is
less
linear
in
response
than
the
sea
led
box
but
with
noticeably
more
output
at
the
tuning
frequency
Advantages
of
vented
enclosures:
•
High
er
ave
rage
output
than
sea
led
•
Tuning
frequency
can
be
easily
adjusted
by
changing
port
l
ength
•
Deep
bass
response
with
lower
power

•
Great

high

Infinite
Baffle
Design
Th
ese
designs
typically
called
"IB",
are
the
eas
i
est
enc
lo
sure
types
to
build
.
Th
e
reason
is
that
you
are
not
actually
building
an
enclosure,
but
r
ather
s
imul
ating
one
.
This
is
done
by
closing
off
a
cavity
area
(ie;
car
trunk
,
enclosed
ar
ea
of
a
boat
hull)
with
a
baffle
board.
This
creates
your
"
IB"
sub-woofer
system.
Essentially,
an
"IB"
de
s
ign
can
ju
st
be
considered
a
large
sea
led
e
nclo
su
re
design.
Given
that
an
"IB"
design
does
not
rely
on
a
volume
of
air
for
its
suspension,
the
low
frequenc
y
output
is
driven
by
the
speaker's
inherent
damping
or
"Ole".
Advantages
of
infinite
baffle
design:
•

•
Light-weight

Building
an
Enclosure
To
work
pr
o
perly,
the
walls
of
the
enc
lo
sure
must
be
rigid
and
not
flex
when
sub-
jected
to
the
high
pressures
gen
er
ated
by
the
speaker'
s
ope
r
at
io
n.
For
optimum
performance,
we
recommend
using
3/4"
MDF
(Medium
Dens
it
y
Fiberboard)
and
internal
bracing.
The
enclosure
sho
uld
be
glued
together
and
secured
with
nails
or
screws.
Calculating
Volume
Calculating
volume
is
merely
a
matte
r
of
measuring
the
di
me
ns
io
ns
in
inches
a
nd
using
the
form
ula:
HxWxD
divid
ed
by
1728

feet
).

The

of
the

reduces
the

so
this
must
be
subtracted
from
the
outside

to
determ
