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" 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. –3– ® 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 connected across each other. A SeriesParallel configuration is a combination of both methods. Determine which method will be compatible with your amplifier. 8Ω Series Wiring Cableado en serie Câblage en série Reihengeschaltet Cablaggio di serie ++ 4Ω x 2 2Ω Parallel Wiring Cableado en paralelo Câblage parallèle Parallelgeschaltet Cablaggio parallelo = RT 1 R1 + 1 R2 + 1 R3 + - - RT = R1 + R2 + R3 + etc. 1 + 1 +- + + - - 4Ω x 2 + etc. R4 4Ω Series-Parallel Wiring Cableado en serie/paralelo Câblage/en série/parallèle Reihen-/parallelgeschaltet Cablaggio di serie/parallelo ++ + + + - - - 4Ω x 2 - 4Ω x 2 • RT indicates the total speaker load • R1, R2, etc. indicates each speaker in the system • Colored Dot indicates “+” terminal of each 4 ohm voice coil –4– ® I N S T A L L A T I O N L IMITED W A R R A N T Y I N F O R M AT I O N Rockford Corporation offers a limited warranty on Rockford Fosgate products on the following terms: • Length of Warranty 1 year on speakers 3 years on electronics 1 years on source units 90 days on speaker B-stock (receipt required) 90 days on electronic B-stock (receipt required) • What is Covered This warranty applies only to Rockford Fosgate products sold to consumers by Authorized Rockford Fosgate Dealers in the United States of America or its possessions.

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. CALCULO DEL VOLUMEN Para calcular el volumen sólo se han de medir las dimensiones en centimetros y aplicar la fórmula: Volumen du la caja = (en litros) Alto x Ancho x Profundidad 1000 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. –7– E SPAÑOL INTRODUCCÍON VEUILLEZ LIRE LES INSTRUCTIONS SUIVANTES POUR L'INSTALLATION DE CE PRODUIT. I NTRO D UC TI O N 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. CALCUL DU V OLUME Volume du caisson = Hauteur (cm) x Longueur (cm) x Largeur (cm) 1000 (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 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. –8– FRANCAIS On calcule le volume en mesurant la dimension de chaque côté et en utilisant la formule suivante: BITTE LESEN SIE DIESE GEBRAUCHSANLEITUNG ZUERST SORGFÄLTIG DURCH.

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. V OLUMEN -B ERECHNUNG Zur Volumen-Berechung benötigen sie die genauen Maβe und Dimensionen in Zentimetern. GehäuseVolumen = Höhe (cm) x Breite (cm) x Tiefe (cm) 1000 (Kubik Liter) D ER G EHÄUSE B AU 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. –9– 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 Innen-Volumen, auch er sollte natürlich heraus gerechnet werden. Jedes Lautsprecher-Volumen ist unter “Specifications” genau aufgelistet. LEGGERE CON ATTENZIONE LE SEGUENTI ISTRUZIONI PRIMA DELL'INSTALLAZIONE DEL PRODOTTO. 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. 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 = Alteza x Larghezza x Profonditá 1000 (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. 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. – 10 – ITALIANO COSTRUIRE UNA CASSA NOTES – 11 – e by c n a m r perfo m u m i x ate m i Get ma t l u r the o f g n i surf s at: n g i s e stem d y s h c Pun te.com a g s o f kford c o r . w ww MADE IN THE USA This product is designed, developed and assembled in the USA by a dedicated group of American workers.
