Introduction

The Punch HE2 DVC, Punch HX2 DVC, Power HX2 DVC are high perfor­mance, low frequency drivers with dual voice coils. These woofers were
designed for use primarily in small sealed and small ported enclosures. By
utilizing the latest materials and construction techniques, we are able to
offer a speaker with high output at low frequencies while requiring a mini­mum of operating space.

This manual outlines two specific types of enclosures that
provide distinctly different performance. This section is to
help you decide which type is best for your application.

Sealed

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

Recommended Enclosures

Vented Enclosures

Vented enclosures vary only from the sealed enclosure in that a vent or
port is added to “tune” the enclosure. The enclosures recommended are
designed for great overall performance. Larger boxes tend to be easy to
tune to lower frequencies while medium and small boxes are easier to
tune to higher frequencies. The vented design is less linear in response
than the sealed box but with noticeably more output at the tuning
frequency.

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 with limited power

Wiring Configurations

By varying the wiring configuration of your speakers you can create an
impedance load to match your system. Since each voice coil of a DVC
speaker carries its own impedance, altering the wiring configurations give
a range of options for impedance load. 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 below that corresponds the
number of woofers and the impedance of your amplifier.

5

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. MDF is porous; therefore, it is suggested
to also seal the outside walls with polyurethane.

CALCULATING VOLUME

Calculating volume is merely a matter of measuring the dimensions in inch­es and using the formula:
If 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.

Box Volume =

(cubic feet)

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 which sep­arates the audio signal fed to different amplifiers. For optimum subwoofer

performance, we recommend using an active 80-100Hz low-pass crossover
at 12dB/octave.

INTRODUCCÍON

Los woofers Power DVC son una gama completa de drivers de baja fre­cuéncia que comprenden diámetros de 10" a 15". Diseñada para ofrecer la
máxima calidad, los Woofers ofrecen al entusiasta principiante en sistemas
de car audio, la oportunidad para disfrutar de un bajo sólido en las bajas
frecuéncias. Nuestros ingenieros han seleccionado materiales y técnicas
para la construcción de nuestros altavoces con el objetivo de ofrecer
características y confianza comparable a otros altavoces vendidos much
más caros.

Volumen
du la caja =

(en litros)

CALCULO DEL VOLUMEN

Para calcular el volumen sólo se han de medir las dimensiones en cen­timetros y aplicar la fórmula:

Si dos caras opuestas son de diferente tamaño, súmelas y divida el total por
dos para obtener el promedio. Usando esta técnica se ahorrara el cálculo
por secciones. El espesor del material con que está construida la caja
reduce el volumen interno, de manera quer ha de restarse de las dimen­siones exteriores para determinar el volumen interior. La cantidad de aire
que ocupa cada modelo viene especificado en la hoja de caracteristicas y
también debe sustraerse para obtener el volumen neto interior.

CONSTRUCCION DE UN RECINTO

Para un buen funcionamiento las paredes del recinto han de ser rigidas y
sin flexión a altas presiones de aire. Recomendamos usar un espesor de 1.9
cm de conglomerado de alta densidad o fibra de media densidad. Si el
recinto es muy grande es necessario reforzarlo internamente. Las juntas
deben ser encoladas y aseguradas con tornillos o grapas. Internamente las
juntas deben ser selladas con silicona para prevenir las fugas de aire. La
cola para madera es la mejor opción. Debido a la porosidad del conglom­erado de alta densidad y la fibra es recomendable sellar exteriormente la
caja con poliuretano.

INTRODUCTION

Les woofers Power DVC sont une gamme complète de haut-parleurs de
graves allant de 25 à 38 cm et disponibles en 4Ωx2. En utilisant les tech­niques et les matériaux de construction les plus récents, nous sommes
parvenus à construire un haut-parleur fournissant un rendement élevé dans
les graves tout en requérant un volume opérationnel minimum.

Volume
du caisson =

(Litres)

Hauteur (cm) x Longueur (cm) x Largeur (cm)

1000cc3/liter

CALCUL DU VOLUME

On calcule le volume en mesurant la dimension de chaque côté et en
utilisant la formule suivante:

Si les due côtés qui se font face n'ont pas la même longueur, additionnez
les et divisez le résultat par deux pour obtenir la moyenne des deux
longueurs. Utilisez le nombre ainsi obtenu dans la formule pour détermin­er le litrage. Cette méthode permet d'obtenir le volume du caisson sans
devoir faire de calculs compliqués de section de volume. L'épaisseur du
matériau dont est fait le caisson réduit le volume interne de celui-ci.
Lorsqu'on mesure les côtés du caisson il ne faut donc pas oublier d'oter des
mesures l'epaisseur du matériau. Le haut-parleur lui-même diminue le vol­ume interne du caisson. Le volume d'air déplacé par chaque modèle de
haut-parleur est repris dans les spécifications techniques et doit également
être soustrait du volume total.

CONSTRUIRE UN CAISSON

Pour fonctionner convenablement les parois du caisson doivent être rigides
lorsqu'elles sont soumises aux hautes pressions dues au fonctionnement du
haut-parleur. Nous vous recommandons d'utiliser des panneaux de bois
aggloméré à haute ou moyenne densité de particules de type “MDF”. Ces
panneaux sont disponibles dans la plupart des magasins de bricolage. Pour
un caisson de grand volume il est recommandé de placer des renforts à l'in­térieur du caisson. Les différents côtés devront être collés (colle à bois) et
vissés (ou éventuellement cloués). Il est recommandé de mettre un joint de
silicone dans les arêtes internes du caisson afin d'éviter les fuites d'air. Du
fait de la porosité des matériaux que nous vous conseillons il est préférable
de recouvrir l'extérieur du caisson avec du polyuréthane.

EINLEITUNG

Die Power DVC Woofer sind eine komplette Produktlinie von Tief­Frequenzlautsprechern mit Durchmesser von 25 cm bis zu 38 cm,
erhältlich in der Impendanz 4 Ohm x 2. Durch die Verwendung neuester
Materialien und Produktionstechniken können wir Ihnen heute einen
Lautsprecher vorstellen, der hohe Lautstärken und tiefe Frequenzen selbst
in sehr kleinen Volumen reproduzieren kann.

Gehäuse­Volumen =

(Kubik Liter)

Höhe (cm) x Breite (cm) x Tiefe (cm)

1000cc3/liter

VOLUMEN-BERECHNUNG

Zur Volumen-Berechung benötigen sie die genauen Mabe und
Dimensionen in Zentimetern.

Sollten zwei gegenüberliegende Seiten ungleich lang sein, so können sie
die Mabe zusammen rechnen und durch zwei dividieren um den
Durchschnitt zu erhalten. Dies macht Ihnen die Berechnung leichter und
Sie müssen das Gehäuse nicht in Sektionen berechnen, die Sie danach
wieder mühselig zusammen zählen müssen. Die Materialstärke beeinflubt
natürlich auch das Innen-Volumen, so muss für eine präzise Berechnung
die Materialstärke von Auben-Volumen abgezogen werden. Der
Lautsprecher verringert ebenfalls das Innen-Volumen, auch er sollte natür-
lich heraus gerechnet werden. Jedes Lautsprecher-Volumen ist unter
“Specifications” genau aufgelistet.

DER GEHÄUSE BAU

Um das Gehäuse so präzise wie möglich zu bauen, sollten die
Gehäusewände sehr steif und luftundurchlässig sein, um dem entsehenden
Luftdruck des Lautsprechers standhalten zu können. Wir empfehlen 1,9 cm
mittelverdichtete Faserplatte (MDF), die in den meisten Baumärkten ange­boten wird. Bei einem gröβeren Gehäuse sollten Sie Versteifungen durch
Holzbalken montieren. Diese sollten – wie auch das gesamte Gehäuse –
mit Holzleim geklebt und verschraubt oder vernagelt sein. Um eine höhere
Dichte zu erreichen, empfiehlt es sich, die Kanten und Verschraubungen
mit Silikon abzudichten und das Gehäuse von innen mit einer
Hohlraumversiegelung zu behandeln.

INTRODUZIONE

I woofer Power DVC sono una linea completa di altoparlanti per basse fre­quenze con diametri che vanno da 25 a 38 cm e disponibili sia a
4 ohm x 2. Impiegando le piú aggiomate tecnologie e materiali, siamo in
grado di offrire altoparlanti che possono riprodurre un'elevata pressione
sonora alle basse frequenze mantenendo i volumi di impiego assolutamente
ridotti.

Volume
della cassa =

(litri)

Alteza (cm) x Larghezza (cm) x Profonditá (cm)

1000cc3/liter

CALCOLO DEL VOLUME

Calcolare il volume é essenzialmente solo un problema di misurazione
delle dimensioni in centimetri della cassa e di applicazione della formula:

Se due pareti parallele sono di dimensioni diverse (prisma), semplicemente
sommatele e dividete il risulto per due. Impiegando il risultato ottenuto
potete calcolare il volume senza dividere la cassa i sezioni. Lo spessore del
legno riduce il volume interno, per cui é necessario sottrario dalle dimen­sioni esterne. Anche il volume dell'altoparlante stesso riduce il volume
della cassa e deve essere sottratto. Il volume che ciascun altoparlante
contribuisce a togliere dalla cassa é indicato nelle tabelle con le specifiche.

.

COSTRUIRE UNA CASSA

Per ottenere le prestazioni massime, le pareti della cassa devono essere
rigide e non flettere sotto la sollecitaxione della elevata pressione generata
dal woofer. Noi raccomandiamo l'impiego di MDF con uno spessore min­imo di 19 mm, materiale facilmente reperibile in tutte le falegnamerle. Per
casse di dimensioni molto grandi é indispensabile prevedere dei rinforzi
interni. Le giunture devono essere incollate e fissate con viti o chiodi in
abbondanza. Intermanmente le giunture devono essere siliconate per
impedire trafilati d'aria. Anche la colla da legno funziona bene. Essendo il
MDF un materiale poroso si consiglia di sigillare l'esterno con materiali
poliuretanici.
