INTRODUCTION
Punch DVC Woofer
Installation & Owner's Manual
TECHNICAL DESIGN FEATURES
The Punch Dual Voice Coil woofers are low frequency drivers
designed primarily for usein 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 tech-
niques, 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
necessarycombination ofweight andstrength andallows high levels
of output without cone break-up. The cone is treated with a water
resistantPolyVinylAcetate(PVA) Emulsion whichincreasesthecone
rigidity and lowers distortion.
THE RESULT: Increases cone rigidity and lowers distortion.

◆Santoprene Rubber Surround
The santoprene material is resilient to temperature variations and
provides a consistent support necessary for the linear motion of the
speakercone.Inaddition,theinherentdampingcapabilitieseliminates
thetransmissionofsonicdisturbancesbetweenthe 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.
THERESULT:Reducesmechanicaldistortionforbettersoundquality.
◆Powder Coat Finish
Powder coating has long been the industry standard for durability in
protective metal finishes. A dry powder (non-aerosol) is electrostati-
callyappliedtothemetaland“bakedontoprovideahard“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
Theuseoftheinverteddustcapservestoincreasetheconerigidityand
improve the power handling by forcing more air through the voice
coil.
THE RESULT: Increases cone rigidity, smooths frequency response
andpreventsyourfriendsfromfeelingobligatedtoinvertthemforyou.

◆Aluminum Voice Coil Former
Thevoicecoilformerisblack,anodizedaluminumforhighlyefficient
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
excursionwithoutbottomingout.Thisenablesthespeakertobeused
in a smaller enclosure. Additionally, the back plate is vented with a
radiused aerodynamic back vent which efficiently and quietly circu-
lates 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 imped-
ance 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 4Ωor 1Ωload.
These configurations allow a multitude of amplifiers to be used with
the Punch DVC.
THE RESULT: Allows multiple wiring configurations.

Building an Enclosure
Toworkproperly,thewallsoftheenclosuremustberigidandnotflex
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 enclo-
sure 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)
Iftwofacingsidesareofunevenlength,addthemtogetheranddivide
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.
Passivecrossovers(coilsorinductors)areplacedonthespeakerleads
between the amplifier and speaker. An active crossover is an elec-
tronic filter which separates the audio signal fed to different amplifi-
ers. 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.

INTRODUZIONE
I woofer Punch a doppia bobina sono altoparlanti a bassa frequenza
progettati soprattutto per l'9mpiego in cassa chiusa di limitato vol-
ume. 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.
Iconnettori di ingressopositivi enegativi sono montatisul cestelloin
posizioni speculari. Il montaggio separato impedisce al segnale

di ingresso é indicato da una marcatura colorata sul cestello.) Un
contrassengno rosso indica che l'impedenza dell'altoparlante é 8

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

Se due pareti parallele sono di dimensioni diverse (prisma),
semplicemente sommatele e dividete il risulto per due. Impiegando
ilrisultatoottenutopotetecalcolareilvolumesenzadividerelacassa
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.
