Introduction
The RF Punch HE Woofers are a full line of low frequency drivers sized
from 8" to 15" and are available in 4 or 8 ohm impedance. The RF Punch
HE woofers were designed for use primarily in small, sealed or 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.

Installation & Owner's Manual
Recommended Enclosures
This manual outlines 2 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 con-
struction and prevent air leaks. The box volume will directly impact the
performance of the speaker. Larger enclosure 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 enclosures 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 with noticeably more output at the tuning frequenc
y.
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

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:
1728"/(cu in/cu ft)
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 with-
out 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 sep-
arates the audio signal fed to different amplifiers.
For optimum subwoofer
performance, we recommend using an active 80-100Hz low-pass
crossover at 12dB/octave.
7
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 wired in an string (end to end). A Parallel configuration
consists of two or more speakers wired with the common terminals con-
nected across each other. A Series-Parallel configuration is a combination
of both methods. Determine which method will be compatible with your
amplifier.

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 conglom-
erado de alta densidad y la fibra es recomendable sellar exteriormente la
caja con poliuretano.

Calcul Du Volume
On calcule le volume en mesurant la dimension de chaque côté et en util-
isant 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 détermin-
er 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 vol-
ume 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.

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'in-
térieur 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 HE 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 HE Woofer wur-
den 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 repro-
duzieren kann.
Die Anschluβterminals wurden auf jeder Seite des Lautsprecherkorbes posi-
tioniert um eventuelle Kurzschlüsse auch bei hoher Leistung
auszuschlieβen (Das Positiv-Terminal ist durch eine Farbmarkierung geken-
zeichnet). 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
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 beeinflu
βt
natürlich auch das Innen-Volumen, so muss für eine präzise Berechnung
die Materialstärke von Au
βen-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.

Zur Volumen-Berechung benötigen sie die genauen Maβe und

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 ange-
boten wird. Bei einem grö
βeren 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.

LEGGERE CON ATTENZIONE LE SEGUENTI ISTRUZIONI PRIMA DEL-
L'INSTALLAZIONE DEL PRODOTTO.
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 indi-
cato da una marcatura colorata sul cestello.) Un contrassengno rosso indi-
ca che l'impedenza dell'altoparlante é 8 ohm, il contrassegno viola é imp-
iegato per i 4 ohm.
Introduzione
I woofer RF Punch HE sono una linea completa di altoparlanti per basse fre-
quenze con diametri che vanno da 20 a 46 cm e disponibili sia a 4 che a
8 ohm. (I woofer RF Punch HE sono progettati per il funzionamento princi-
pale 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.

Calcolo del Volume
Calcolare il volume é essenzialmente solo un problema di misurazione
delle dimensioni in centimetri della cassa e di applicazione della formula:
Volume della
cassa =
(litri)
1000cc
3
/litri
Alteza (cm) x Larghezza (cm) x Profonditá (cm)
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 dimen-
sioni esterne. Anche il volume dell'altoparlante stesso riduce il volume
della cassa e deve essere sottratto. Il volume che ciascun altoparlante con-
tribuisce a togliere dalla cassa é indicato nelle tabelle con le specifiche.
16
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 min-
imo 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.

The RF Punch HE woofers were designed for use primarily in small, sealed or 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. RF Punch Woofer Contents RF Punch HE Woofer Installation & Owner's Manual +- I N S T A L L A T I O N Recommended Enclosures This manual outlines 2 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 enclosure 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 2 Recommended Enclosures +- I N S T A L L A T I O N Vented Enclosures: Vented enclosures vary only from the sealed enclosures 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 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 3 Installation +- Punch 8" Recommended Enclosures I N S T A L L A T I O N Recommended Ported .625ft3 (17.70L) H = 11" (27.94cm) H = 11" (27.94cm) Recommended Sealed .30ft3 (8.50L) W = 19.75" (50.16cm) D = 8" (20.32cm) W = 11" (27.94cm) D = 8" (20.32cm) Range in Cubic Feet 2 3 4 5 0.3 .50 .625 1 1.50 .50 0.3 Range in Cubic Feet 6 1 2 3 4 5 6 Fb = 40 Hz Pd = 2.5" (6.35cm) Pl = 11.25" (28.57cm) Punch 10" Recommended Ported 1.0 ft3 (28.32L) H = 14" (35.56cm) H = 13" (33.02cm) Recommended Sealed .75ft3 (21.24L) W = 15" (38.10cm) W = 15" (38.1cm) D = 10" (25.40cm) 3 4 5 0.3 2 6 .75 1 1.50 .625 .75 0.3 Range in Cubic Feet D = 13.5" (34.29cm) Range in Cubic Feet 1 2 3 4 5 6 Fb = 35 Hz Pd = 3" (7.62cm) Pl = 13.25" (33.65cm) Punch 12" Recommended Ported 2.0 ft3 (56.63L) H = 18" (45.72cm) H = 14" (35.56cm) Recommended Sealed 1.25ft3 (35.40L) W = 19-3/4" (50.17cm) D = 12" (30.48cm) W = 20.5" (52.07cm) 3 4 5 6 4 1 1.50 2 0.3 1.75 1.25 0.3 1 D = 14" (35.56cm) Range in Cubic Feet Range in Cubic Feet 2 3 4 5 6 Fb=35 Hz Pd=4" (10.16cm) Pl=10.75" (27.30cm) Recommended Enclosures +- I N S T A L L A T I O N Punch 15" Recommended Enclosures Recommended Ported 2.5ft3 (70.79L) H = 20" (50.80cm) H = 20" (43.18cm) Recommended Sealed 2.5ft3 (70.79L) W = 25" (48.26cm) D = 12" (30.48cm) 3 4 5 0.3 6 1 75 2 2.50 1 1.75 0.3 D = 12" (44.45cm) Range in Cubic Feet Range in Cubic Feet 2 50 W = 25" (63.50cm) 3 4 5 6 Fb = 35 Hz Pd = 4" (10.16cm) Pl = 8" (20.32cm) 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: Box Volume= Height” x Width” x Depth” (cubic feet) 1728"/(cu in/cu ft) 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. 6 +- Wiring Configurations I N S T A L L A T I O N Three configurations for connecting speakers to an amplifier are Series, Parallel, and Series-Parallel wiring. A Series configuration 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.

Introduccíon Los woofers RF Punch HE son una gama completa de drivers de baja frecuéncia que comprenden diámetros de 8" a 15". Los Woofers RF Punch HE 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 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. 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 Alto (cm) x Ancho (cm) x Profundidad (cm) la caja = 1000cc3/litros (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 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. 9 ESPAÑOL 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. 10 FRANÇAIS VEUILLEZ LIRE LES INSTRUCTIONS SUIVANTES POUR L'INSTALLATION DE CE PRODUIT. Introduction Les woofers RF Punch HE sont une gamme complète de haut-parleurs de graves allant de 20 à 46 cm et disponibles en 4Ω ou 8Ω. Les woofer RF Punch HE 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. BORNIERS 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 hautparleurs 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 caisson = (Litres) Hauteur (cm) x Longueur (cm) x Largeur (cm) 1000cc3/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. 11 FRANÇAIS 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. 12 DEUTSCH BITTE LESEN SIE DIESE GEBRAUCHSANLEITUNG ZUERST SORGFÄLTIG DURCH. DAS KANN SIE VOR FALSCHEM EINSATZ, AUSFALLEN ODER SOGAR BESCHÄDIGUNG DES PRODUKTES ODER IHRES FAHRZEUGES SCHÜTZEN. Einleitung Die RF-Punch HE Woofer sind eine komplette Produktlinie von TiefFrequenzlautsprechern mit Durchmesser von 20 cm bis zu 46 cm, erhältlich in der Impendanz 4 - und 8 Ohm (Die RF Punch HE 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. Anschlubterminals 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 Zur Volumen-Berechung benötigen sie die genauen Maβe und Dimensionen in Zentimetern. GehäuseVolumen = (Kubik Liter) Höhe (cm) x Breite (cm) x Tiefe (cm) 1000cc3/Kubik liter 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 Innen-Volumen, auch er sollte natürlich heraus gerechnet werden. Jedes Lautsprecher-Volumen ist unter “Specifications” genau aufgelistet. 13 DEUTSCH 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. 14 ITALIANO LEGGERE CON ATTENZIONE LE SEGUENTI ISTRUZIONI PRIMA DELL'INSTALLAZIONE DEL PRODOTTO. Introduzione I woofer RF Punch HE 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. (I woofer RF Punch HE sono progettati per il funzionamento 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 problema di misurazione delle dimensioni in centimetri della cassa e di applicazione della formula: Volume della Alteza (cm) x Larghezza (cm) x Profonditá (cm) cassa = (litri) 1000cc3/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. 15 ITALIANO 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. 16 Notes 17 Notes 18 Notes 19 Installation assistance available at: http://www.rockfordfosgate.com/rftech MADE IN THE USA This product is designed, developed and assembled in the USA by a dedicated group of American workers.
