SEALED
ENCLOSURES
Sealed
enclosures
are
the
simplest
to
build.
The
most
important
part
of
building
a
sealed
enclosure
is
to
make
sure
that
the
enclosure
is
airtight.
Using
glue
and
some
type
of
sealant
on
all
seams
will
ensure
solid
construction
and
prevent
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
greater
SPL.
Advantages
of
sealed
enclosures:
•
Small
enclosures
•
Linear
(Flat)
response
•
No
port
noise
•
High
power
handling
at
all
frequencies
•
Excellent
for
sound
quality
•
Extended
low
frequency
output
when
compared
to
vented
enclosures
BUILDING
AN
ENCLOSURE
To
work
properly,
the
walls
of
the
enclosure
must
be
rigid
and
not
flex
when
subjected
to
the
high
pressures
generated
by
the
speaker
's
operation
.
For
optimum
performance
,
we
recommend
using
3/4
"
MDF
(Medium
Density
Fiberboard)
and
internal
bracing.
The
enclosure
should
be
glued
together
and
secured
with
nails
or
screws.
CALCULATING
VOLUME
Calculating
volume
is
merely
a
matter
of
measuring
the
dimensions
in
inches
and
using
the
formula:
HxWxD
divided
by
1728
(cubic
feet).
See
block
below.

Tlf
two
facing
sides
are
of
uneven
length
,
add
them
together
and
divide
by
two
to
take
the
average.
Using
this
number
will
give
you
the
volume
without
the
necessity
of
calculating
the
box
in
sections
and
adding
the
sections
together
.
The
thickness
of
the
baffle
material
reduces
the
internal
volume
so
this
must
be
subtracted
from
the
outside
dimensions
to
determine
the
internal
volume.
The
speaker
itself
also
reduces
the
internal
volume.
The
amount
of
air
displaced
by
each
model
is
listed
on
the
specification
sheet
and
should
also
be
subtracted
from
the
gross
volume
calculation
.
*NOTE:

be
added
to
this

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
configurations are different techniques for wiring speakers that provide different
loads . Series 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
crossovers (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 recommend using an active 80-1 OOHz low-pass crossover at 12dB/octave.
CAUTION: Before installation , disconnect the battery negative (-)terminal to
prevent damage to the unit, fire and/or possible injury.
FRAN~AIS
MISE EN GARDE: avant d' entamer ! 'i nstallation , deconnectez Ia broche negative
(-) de Ia batterie pour eviter tout risque de blessures , d'incendie ou de dommages
al' appareil.
PRATIQUEZ UNE ECOUTE SANS RISQUESMD
Une exposition continue a des niveaux de pression acoustique superieurs
a 100 dB peut causer une perte d' acuite auditive permanente. Les
systemes audio de forte puissance pour auto peuvent produire des
niveaux de pression acoustique bien au-dela de 130 dB . Faites preuve de
bon sens et pratiquez une ecoute sans risques
Enceintes Etanches
Les e.nceintes etanches sont les plus faciles a fabriquer. A cet egard, Ia chose Ia
plus 1mportante dans leur fabrication est de vous assurer qu ' elles sont vraiment
hermetiques.Appliquez de Ia colle et un produit d'etancheite sur tousles jointg '
pour solidifier I' ensemble et empecher toute fuite d'air. Le volume du caisson
influe directement sur Ia performance du haut-parleur. Les enceintes de plus
grande dimension delivrent une reponse uniforme en frequence avec des graves
profonds_ alors que les enceintes plus petites ont une courbe de reponse plus
prononcee et un rendement generalement superieur pour un niveau de pression
acoustique plus eleve .
Avantage des enceintes etanches:
• Petites enceintes
• Reponse lineaire (uniforme)
• Pas de bruit d' event
• Puissance elevee sur toutes les frequences
• Excellentes en ce qui concerne Ia qualite du son
Construire Un Caisson
Pour fonctionner convenablement les parois du caisson doivent etre rig ides
lorsqu ' elles sont soumises aux hautes pressions dues au fonctionnement
du haut-parleur. Nous vous recommandons d'utiliser des panneaux de bois
agglomere a haute ou moyenne densite de particules de type "MDF". Ces
panneaux sont disponibles dans Ia plupart des magasins de bricolage. Pour un
caisson de grand volume il est recommande de placer des renforts al 'i nterieur
~u caisson. Les diffe _ rents cotes devront etre co lies (co lie a bois) et visses ( ou
eventuellement cloues). II est recommande de mettre un joint de silicone da ns les
ari:ltes internes du caisson afin d' eviter les fuites d' air.
Calcu du Volume
On calcule le volume en mesurant Ia dimension de chaque cote et en utilisant Ia
formule suivante:
Volume du caisson
Divise pres (Litres)
Hauteur (em) x Longueur (em) x Largeur (em)
1000
Si les due cotes qui se font face n' ont pas Ia meme longueur, additionnez les et
divisez le resultat par deux pour obtenir Ia moyenne des deux longueurs. Utilisez
le nombre ainsi obtenu dans Ia formule pour determiner le litrage. Cette methode
permet d'obtenir le volume du caisson sans devoir faire de calculs compliques
de section de volume. L' epaisseur du materiau dont est fait le caisson reduit le
volume interne de celui-ci. Lorsqu ' on mesure les cotes du caisson il ne taut done
pas oublier d'oter des mesures l' epaisseur du materiau. Le haut-parleur lui-meme
diminue le volume interne du caisson. Le volume d'air deplace par chaque modele
de haut-parleur est repris dans les specifications techniques et doit egalement etre
soustrait du volume total.
Configuration du cablage
En variant Ia configuration du cablage de vos haut-parleurs, vous pouvez creer
une charge d' impedance correspondant a votre systeme. La modification des
configurations de cablage offre tout un choix d'options en ce qui concerne Ia
charge d' impedance. Les cablages serie, parallele, ou serie/parallele sont des
techniques permettant de Cabler les haut-parleurs de maniere a produire des
charges differentes . La configuration serie consiste a cabler les haut - parleurs
a Ia chaine , bout a bout. La configuration parallele utilise deux ou plusieurs
haut-parleurs branches sur des bornes communes. La configuration serie/parallele
combine les deux techniques. Choisissez le schema ci-dessous qui correspond au
nombre de haut-parleurs de graves eta !' impedance de votre ampli .
Filtres de subwoofer
On distingue deux types de filtres operationnels : passif et actif. Les filtres passifs
(bobines ou inducteurs) sont places sur les fils de haut - parleur , entre l' ampli et
le hautparleur . Un filtre actif est un filtre electronique qui separe le signal audio
envoye a differents amplis. Pour obtenir une performance optimale du subwoofer ,
nous recommandons !'utilisation d' un filtre actif passe-bas 80 - 100 Hz a 12 dB/
octave.
