RECOMMENDED
ENCLOSURES
This manual outlines
two
specific
typesofenclosures
that
provide
distinctly different
performance.
This
sectionisto
help you decide
which
typeisbest
for
your
application.
SEALED
ENCLOSURES
Sealed
enclosures
are
the
simplesttobuild.
The
most
important
part
of
building a sealed
enclosureisto
make
sure
that
the
enclosureisairtight.
Using glue and
some
typeofsealantonail
seams
will
ensure
solid
construction
and
prevent
air leaks.
The
box
volume will directly impact
the
performanceofthe
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
greater
SPL.
BUILDING
AN
ENCLOSURE
To
work
properly,
the
wallsofthe
enclosure
mustberigid and
not
flex
when
subjectedtothe
high
pressures
generatedbythe
speaker's
operation.
For
optimum
performance,werecommend
using 3/4" MDF
(Medium Density Fiberboard) and internal bracing.
The
enclosure
should
be
glued
together
and
secured
with nailsorscrews.
CALCULATING
VOLUME
Calculating volumeismerely a
matterofmeasuring
the
dimensions
in
inches and using
the
formula: H x W x D divided by 1728 (cubic feet).
See
block
below.

Advantages ofsealed enclosures:
Small
enclosures
Linear (Flat)
response
No
port
noise
High
power
handlingatall
frequencies
Excellent
for
sound
quality
Extended low frequency
output
when
comparedtovented
enclosures
VENTED
ENCLOSURES
Vented
enclosures
vary only from
the
sealed
enclosureinthatavent
or
portisaddedto"tune"
the
enclosure.
The
enclosures
recommended
are
designed
for
great
overall
performance.
Larger boxes
tendtobe easy
to
tunetolower
frequencies while medium and small boxes
are
easier
to
tunetohigher frequencies.
The
vented
designisless linear
in
response
than
the
sealed
box
but
with noticeably
more
output
at
the
tuning frequency.

If
two
facing sides
areofuneven length, add
them
together
and divide by
twototake
the
average. Using this
number
will
give you
the
volume
without
the
necessityofcalculating
the
boxinsections and adding
the
sections
together.
The
thicknessofthe
baffle material
reduces
the
internal
volume
so
this
mustbesubtracted
from
the
outside
dimensions
to
determine
the
internal volume.
The
speaker
itself also
reduces
the
internal volume.
The
amountofair displaced by each modelislisted
on
the
specification
sheet
and should alsobesubtracted
from
the
gross
volume calculation.
Advantages of
vented
enclosures:
Higher average
output
than
sealed
Tuning frequency can
be
easily adjusted by changing
port
length
Deep
bass
response
with
lower
power
requirements
Great
for
high
output

limited
power
