IN TRO D U C TI O N
The RF Punch Woofers are a full line of low frequency drivers sized
from 8" to 18" and are available in 4 or 8 ohm impedance. The RF
Punch woofers were designed for use primarily in small, sealed
enclosures. By utilizing the latest materials and construction tech-
niques, we are able to offer a speaker with high output at low
frequencies while requiring a minimum of operating space.

RF Punch Woofer
Installation & Owner's Manual
TECHNICAL D ESI G N FEAT U RES
◆ Stamped Basket
The RF Punch Woofers use a stamped Cold Rolled Steel basket which
is rigid and lightweight. The basket is finished in a corrosive resistant
powder coated applied process used in many automotive applica-
tions.
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
◆ Inverted Dust Cap
The use ofthe inverted dustcap servesto increase the cone rigidityand
improve the power handling by forcing more air through the voice
coil.
THE RESULT: Increases cone rigidity, smooths frequency response
and preventsyourfriendsfrom feelingobligated to invertthem foryou.

◆ 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
◆ Four-Layer Voice Coil
Multiple layers of high temperature copper wire are wound on the
Aluminum Voice Coil for efficient thermal transfer. The massive voice
coil increases XMAX and adds to the moving mass of the speaker. This
lowers the Fs of the speaker for better low frequency response and
increases the power handling.
THE RESULT: Increases XMAX and power handling
◆ Dual Laminated Foam Surrounds
The RF Punch Woofers employ a dual laminate foam surround for the
front of the woofer's suspension. Dual lamination improves reliability
by making the woofer mechanically stronger.
THE RESULT: Adds mechanical strength
◆ 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 circu-
lates cool air around the voice coil.
THE RESULT: More excursion and increased power handling

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 enclo-
sure 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:
Height x Width x Depth
Box Volume =
(cubic feet)
1728"
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 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
O
N
Three configurations for connecting speakers to an amplifier
are Series, Parallel, and Series-Parallel wiring. A Series con-
figuration consists of two or more speakers wired in an string
(end to end). A Parallel configuration consists of two or more
speakers 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.

INSTALACÍON DEL PRODUCTO.
INTRODUCCÍON
Los woofers RF son una gama completa de drivers de baja frecuéncia
que comprenden diámetros de 8" a 15". Los Woofers RF fueron
diseñados para su utilización en caja cerrada o bass-reflex mediana.
Diseñada para ofrecer la máxima calidad, los Woofers RF ofrecen al
entusiasta principiante en sistemas de car audio, la oportunidad para
disfrutar de un bajo sólido en las bajas frecuéncias. Nuestros
ingenieroshan seleccionado materialesytécnicaspara la construcción
de nuestros altavoces con el objetivo de ofrecer características y
confianza comparable a otros altavoces vendidos much más caros.
TERMINALES DE ENTRADA
Los terminales positivo y negativo de entrada están ubicados uno en
cada extremo de la carcasa. Este montaje separado previene de
posibles cortocircuitos de la señal a altos niveles de volumen. El
terminal positivo está marcado con un punto en la carcasa. Un punto
rojo indica que la impedancia del altavoz es de 8 ohmios, y un punto
violeta que es de 4 ohmios.

CALCULO DEL VOLUMEN
Para calcular el volumen sólo se han de medir las dimensiones en
centimetros y aplicar la fórmula:
Volumen du
la caja =
Alto x Ancho x Profundidad
1000
(en litros)
Si dos caras opuestas son de diferente tamaño, súmelas y divida el
total por dos para obtener el promedio. Usando esta técnica se
ahorrara elcálculo porsecciones. Elespesordelmaterialcon 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.

IN TRO D U C TI O N
Les woofers Punch sont une gamme complète de haut-parleurs de
graves allant de 20 à 46 cm et disponibles en 4Ω ou 8Ω. Les woofer
Punch ont été conçus pour être utilisé de préférence en enceintes
closes.
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.
BO RN IERS
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 haut-
parleurs de 4Ω.

CALCUL DU VOLUME
On calcule le volume en mesurant la dimension de chaque côté et en
utilisant la formule suivante:
Volume du
Hauteur (cm) x Longueur (cm) x Largeur (cm)
1000
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.
CONSTRUIRE UN CAISSON
Pour fonctionner convenablement les parois du caisson doivent être
rigides lorsqu'elles sont soumises aux hautes pressions dues au
fonctionnementdu haut-parleur. Nousvousrecommandonsd'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 RF-Punch Woofer sind eine komplette Produktlinie von Tief-
Frequenzlautsprechern mit Durchmesser von 20 cm bis zu 46 cm,
erhältlich in der Impendanz 4 - und 8 Ohm (Die RF Punch Woofer
wurden vorwiegend fur den Einsatz in geschlossenen Gehäuse
konstruiert). 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.

VOLUMEN-BERECH NUNG
Zur Volumen-Berechung benötigen sie die genauen Maβe und
Dimensionen in Zentimetern.
Gehäuse-
Volumen =
(Kubik Liter)
Höhe (cm) x Breite (cm) x Tiefe (cm)
1000
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 wiedermühseligzusammen 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 Innen-
Volumen, auch er sollte natürlich heraus gerechnet werden. Jedes
Lautsprecher-Volumen ist unter “Specifications” genau aufgelistet.
DER GEH ÄUSE 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 Punch RF sono una linea completa di altoparlanti per basse
frequenze con diametri che vanno da 20 a 46 cm e disponibili sia a
4 che a 8 ohm. (IwooferPunch RFsono progettatiperilfunzionamento
principale in cassa chiusa.). 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.
CONNESSIONI DI INGRESSO
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.

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
Alteza x Larghezza x Profonditá
1000
cassa =
(litri)
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.
