INTRODUCTION

Punch DVC Woofer
Installation & Owner's Manual

TECHNICAL DESIGN FEATURES

The Punch Dual Voice Coil woofers are low frequency drivers
designed primarily for use in small, sealed or vented enclosures. The
dual voice coil design allows low impedance loads to be configured
for optimizing the performance of Punch Power 50.1 and 50.2
amplifiers. By utilizing the latest materials and construction tech­niques, we are able to offer a speaker with optimized low frequency
response while requiring a minimum of operating space.

DVC WOOFER CONTENTS

◆ Stamped Basket

The Dual Voice Coil Woofers use a stamped Cold Rolled Steel basket
which is rigid and lightweight. The basket is finished in a corrosive
resistant power coated applied process used in many automotive
applications.

THE RESULT: A lightweight and rigid woofer.

◆ PVA Cone

The cone material used is spruce pulp paper. This provides the
necessary combination of weight and strength and allows high levels
of output without cone break-up. The cone is treated with a water
resistant PolyVinyl Acetate (PVA) Emulsion which increases the cone
rigidity and lowers distortion.

THE RESULT: Increases cone rigidity and lowers distortion.

– 2 –

◆ Santoprene Rubber Surround

The santoprene material is resilient to temperature variations and
provides a consistent support necessary for the linear motion of the
speaker cone. In addition, the inherent damping capabilities eliminates
the transmission of sonic disturbances between the cone and the frame
of the speaker. This greatly improves the clarity of the speaker's
frequency response.

THE RESULT: Improves speaker's frequency response.

◆ Flat Spider

The speaker's linear compliance is balanced through the use of a
“proprietary” flat spider design. A flat spider provides symmetrical
control of the voice coil through its cone excursion. Linear cone
excursion reduces harmonic distortion for improved sound quality.

THE RESULT: Reduces mechanical distortion for better sound quality.

◆ Powder Coat Finish

Powder coating has long been the industry standard for durability in
protective metal finishes. A dry powder (non-aerosol) is electrostati­cally applied to the metal and “baked on to provide a hard “shell-like”
finish. As an additional benefit, powder coating is the only finishing
process that releases no toxic chemicals into our ozone.

THE RESULT: A durable and “earth friendly” metal finish.

◆ Inverted Dust Cap

The use of the inverted dust cap serves to increase the cone rigidity and
improve the power handling by forcing more air through the voice
coil.

THE RESULT: Increases cone rigidity, smooths frequency response
and prevents your friends from feeling obligated to invert them for you.

– 3 –

◆ Aluminum Voice Coil Former

The voice coil former is black, anodized aluminum for highly efficient
thermal transfer. This allows winding high temperature copper wire
in multiple layers for improved efficiency.

THE RESULT: Improves power handling by efficiently dissipating
heat.

◆ Hyper-Extended Pole Piece

The pole piece has been extended to provide a more linear magnetic
field for the operation of the woofer. This lowers distortion and
provides the woofer with better low frequency response.

THE RESULT: Lowers distortion and provides better low frequency
response.

◆ Vented Bumped Back Plate

The back plate has been stepped deeper to allow the woofer more
excursion without bottoming out. This enables the speaker to be used
in a smaller enclosure. Additionally, the back plate is vented with a
radiused aerodynamic back vent which efficiently and quietly circu­lates cool air around the voice coil.

THE RESULT: More excursion and increased power handling.

◆ Dual Voice Coils

The dual voice coil design of the speaker allows a variety of imped­ance loads to be configured. A single woofer can be wired for a 2Ω
load and a pair of woofers can be wired for either a 4Ω or 1Ω load.
These configurations allow a multitude of amplifiers to be used with
the Punch DVC.

THE RESULT: Allows multiple wiring configurations.

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 with nails or screws. Because MDF is
porous, it is suggested to seal the outside walls with polyurethane.

Calculating Volume

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

1728"

Height x Width x Depth

Box Volume =

(cubic feet)

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.

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.

Wiring Configurations

Three configurations for connecting speakers to an amplifier are
Series, Parallel, and Series-Parallel wiring. A Series configuration
consists of two or more speakers (voice coil) wired in an string (end
to end). A Parallel configuration consists of two or more speakers
(voice coils) wired with the common terminals connected across
each other. A Series-Parallel configuration is a combination of both
methods. Determine which method will be compatible with your
amplifier.

INTRODUCTION

Les woofers Punch Double bobine sont des haut-parleurs de basses
fréquences conçus à l’origine pour jouer dans des petits caissons. La
conception à double bobine permet des charges de basses impédances
destinées à optimiser les performances des amplis Punch Power 50.1
et 50.2. Grace à l’utilisation de matériaux dernier cri et des plus
récentes techniques de fabrication, nous pouvons vous offrir un haut­parleur avec une réponse en basses fréquences optimisée ne requérant
qu’un minimum d’espace opérationnel.

FRANÇAIS

Les bornes positives et négatives sont fixées de part et d'autre du
saladier. Cette séparation permet d'empêcher les courts-circuits entre
les fils lors des reproductions sonores élevées. La borne positive est
repérée par un petit point de couleur sur le saladier. Un point rouge
est utilisé pour les haut-parleurs de 8Ω, un point violet pour les haut­parleurs de 4Ω.

BORNIERS

CALCUL DU VOLUME

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

Volume du
caisson =

(Litres)

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.

EINLEITUNG

Die Punch Doppel-Schwingspule Woofer sind Tieffrequenz-Woofer,
die für kleine geschlossene Gehäuse konstruirt wurden. Die Doppel­Schwingspule erlaubt eine sehr niedrige Impedanz, genau richtig für
die Optimierung der Leistung der neuen Punch Power 50.1 und 50.2
Endstufen. Unter der Verwendung neuester Materialien und
konstruktionstechnikjen, können wir Ihnen einen Woofer für sehr
tiefe Frequenzen, in sehr kleinen Gehäusen vorstellen.

ANSCHLUβTERMINALS

Die Anschluβterminals wurden auf jeder Seite des Lautsprecherkorbes
positioniert um eventuelle Kurzschlüsse auch bei hoher Leistung
auszuschlieβen (Das Positiv-Terminal ist durch eine Farbmarkierung
gekenzeichnet). Eine rote Farbamrkierung befindet sich immer bei
einem Lautsprecher mit einer Impedanz von 8 Ohm, eine violette
Farbmarkierung zeichnet die Lautsprecher mit der Impedanz 4 Ohm.

VOLUMEN-BERECHNUNG

DEUTSCH

Sollten zwei gegenüberliegende Seiten ungleich lang sein, so können
sie die Maβe 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
beeinfluβt natürlich auch das Innen-Volumen, so muss für eine
präzise Berechnung die Materialstärke von Auβen-Volumen
abgezogen werden. Der Lautsprecher verringert ebenfalls das Innen­Volumen, auch er sollte natürlich heraus gerechnet werden. Jedes
Lautsprecher-Volumen ist unter “Specifications” genau aufgelistet.

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

LEGGERE CON ATTENZIONE LE SEGUENTI ISTRUZIONI PRIMA
DELL'INSTALLAZIONE DEL PRODOTTO.

INTRODUZIONE

I woofer Punch a doppia bobina sono altoparlanti a bassa frequenza
progettati soprattutto per l'9mpiego in cassa chiusa di limitato vol­ume. Il progetto a doppia bobina consente la configurazione di
carichi a bassa impedenza per ottimizzare le prestazioni degli
amplificatori Punch Power 50.1 e 50.2 Impiegando i materiali e le
tecniche di costruzione piú avanzati, siamo in grado di offrirvi un
altoparlante che ottimizza la risposta a bassa frequenza richiedendo
un minimo spazio operativo.

I connettori di ingresso positivi e negativi sono montati sul cestello in
posizioni speculari. Il montaggio separato impedisce al segnale
musicale di cortocircuitarsi ad altissimi livelli di volume. (Il terminale
di ingresso é indicato da una marcatura colorata sul cestello.) Un
contrassengno rosso indica che l'impedenza dell'altoparlante é 8
ohm, il contrassegno viola é impiegato per i 4 ohm.

CONNESSIONI DI INGRESSO

CALCOLO DEL VOLUME

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

Volume della
cassa =

(litri)

1000

Alteza x Larghezza x Profonditá

ITALIANO

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.
