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.

Installation and Operation Manual
Recommended Enclosures
This manual outlines two specific types of enclosures that provide distinctly different performance. This section is to help you decide which type is best for your
application.
Sealed Enclosures
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
enclosures 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
•
Extended low frequency output when compared to vented enclosures
Calculating Volume
Calculating volume is merely a matter of measuring the dimensions in inches and
using the formula: Hx Wx Ddivided by 1728 (cubic feet). See block below.
Box Volume
Divided by (cubic feet)
Height" x Width" x Depth"
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.
Sealed Enclosure
NOTE: Vb is the internal volume, before any speaker and/or port displacement is added. All external dimensions were based on the use of
3/4" (1.90cm) materials.
Vented Enclosures
Vented enclosures vary only from the sealed enclosure 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 but with noticeably
more output at the tuning frequency.
NOTE: When using enclosures other than recommended, call Technical Support
for correct application.
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

Wiring Configurations
By varying the wiring configuration of your speakers you can create an impedance
load to match your system. Altering the wiring configurations gives a range of
options for impedance loads. Series, Parallel , or Series-Parallel wiring configurations are different techniques for wiring speakers that provide different loads. Series configuration is a string method where speakers are wired end to end. Parallel
configuration uses two or more speakers wired across common terminals. SeriesParallel configuration combines both techniques. Choose the wiring diagram that
corresponds to the number of woofers and the impedance of your amplifier.

NOTE: The port shown can be placed on any face of the enclosure as long as the
port ends are not obstructed.
NOTE: When using vented enclosures, for maximum reliability and power handling ensure, that a subsonic or "infrasonic" filter at or above 27Hz is used so
that only usable low frequency signals are sent to the subwoofer.
Series Wiring

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 that separates the audio
signal fed to different amplifiers. For optimum subwoofer performance, we recommend using an active 80-1 OOHz low-pass crossover at 12dB/octave.

Enceintes recommandees
Ce manuel decrit deux types particuliers d'enceintes aux performances tout afait distinctes.
Cette section vous permettra de decider celui qui vous conviendra le mieux.
Enceintes Etanches
Les enceintes etanches sont les plus faciles afabriquer.A eel egard, Ia chose Ia plus importante dans leur fabrication est de vous assurer qu'elles sont vraiment hermetiques.Appliquez
de Ia co lie et un produit d'etancheite sur taus lesjoints pour solidifier !'ensemble et empecher
toute fuite d'air. Le volume du caisson influe directement sur Ia performance du haut-parleur.
Les enceintes de plus grande dimension delivrent une reponse uniforms en frequence avec
des graves profonds alors que les enceintes plus petites ant une courbe de reponse plus
pr noncee et un rendement generalement superieur pour un niveau de pression acou tique
plus eleve.
Avantage des enceintes etanches:
• Petites enceintes
• Reponse lineaire (uniforme)
• Pas de bruit d'event
• Puissance elevee sur toutes les frequences
• Excellentes en ce qui concerne Ia qua lite duson
Enceintes AEvent
Les enceintes a event se distinguent des enceintes etanches du fait qu'on y ajoute un
event au port pour les " accorder ... Les enceintes reco mandees son! convues pour offrir d'excellentes performances. II est generalement plus facile d'accorder les caissons plus
grands pour !'obtention de basses frequences et les caissons moyens et petits pour des
frequences plus elevees. Les enceintes aevent
ant une reponse mains lineaire que les enceintes etanches mais degagent nettement plus de
puissance aIa frequence d'accord.
Avantages des enceintes aevent :
• Rendement moyen superieur par rapport aux modeles etanches
• Lafrequence d'accord peut etrefacilement reg lee en changeant Ia lo gueur de !'event
• Reproduction profonde des basses avec unepuissance d'entree moindre
• Excellent choix pour un rendement eleve aIaibie puissance d'entree
Construire Un Caisson
Pour fonctionner convenablement les parois du caisson doivent etre rigides lorsqu'elles
sont soumises aux hautes pressions dues au fonctionnement du haut-parleur.Nous vous
recommandons d'utiliser des panneaux de bois agglomere ahaute au moyenne densite de
particules de type "MDF".Ces panneaux son! disponibles dans Ia plupart des magasins de
bricolage. Pour un caisson de grand volume il est recommande de placer des renforts a
l'interieur du caisson. Les differenls cotes devronl eire colles (colle abois) et visses (ou
eventuellement cloues). II est recommande de mettre un joint de silicone dans les aretes
internes du caisson afin d'eviter les fuites d'air.
Calcu duVolume
On calcule le volume en mesurant Ia dimension de chaque cote et en utilisant Ia formule
suivante:
Volume du caisson
Hauteur (em) x Longueur (em) x Largeur (em)
Divise pres (litres)
1000
Si les due cotes qui se font face n'ont pas Ia meme longueur, additionnez les et divisez
le resultat par deux pour obtenir Ia moyenne des deux longueurs.Utilisez le nombre ainsi
obtenu dans Ia formule pour determiner le litrage.Cette methode permet d'obtenir le volume
du caisson sans devoir faire de calculs compliques de section de volume. L'epaisseur du
materiau doni est fait le caisson reduit le volume interne de celui-ci. Lorsqu'on mesure les
cotes du caisson il ne taut done pas oublier d'oter des mesures l'epaisseur du materiau. Le
haut-parleur lui-meme diminue le volume in Ierne du caisson. Le volume d'air deplace par
chaque modele de haut-parleur est repris dans les specifications techniques et doit egalement etre soustrait du volumetotal.
Configuration du cablage
En variant Ia configuration du cablage de vas haut-parleurs, vous pouvez creer une charge
d'impedance correspondant avotre systeme. La modification des configurations decablage
offre tout un choix d'options en ce qui concerne Ia charge d'impedance. Les cablages serie, parallele, au serie/parallele sont des techniques permettant de cabler les haut-parleurs
de maniere aproduire des charges differentes. La configuration serie consiste acabler les
haut-parleurs aIa chaine, bout about. La configuration parallele utilise deux ou plusieurs
haut-parleurs branches sur des barnes communes. La configuration serie/parallelecombine
les deux techniques.Choisissez le schema ci-dessous qui correspond au nombre de hautparleurs de graves et a!'impedance devotre ampli.
Filtres de subwooler
On distingue deux types de filtres operationnels : passif et actif. Les filtres passifs (bobines
ou inducteurs) sont places sur les fils de haut-parleur, entre l'ampli et lehaut-parleur.Un filtre
actif est un filtre electronique qui separe le signal audio envoye a differents amplis. Pour
obtenir une performance optimale du subwoofer, nous recommandons !'utilisation d'un filtre

Cajas recomendadas
Este manual delinea dos tipos especfficos de cajas que producen rendimientos inconfundiblemente diferentes. Esta secci6n es para ayudarle a decidir cual tipo es el mejor para su
aplicaci6n.
Cajas CERRAOAS
Las cajas cerradas son las mas faciles de hacer. La parte mas importante de Ia construcci6n
de una caja cerrada es garantizar su hermetismo. El usa de pegante y alguntipo de sellador
en todos los bordes garantizara una construcci6n salida y evitara fugas de aire. El volumen
de Ia caja impacta directamente el rendimiento del altavoz. Las cajas mas grandes ofrecen
una respuesta mas plana y un bajo mas profundo,mientras que las mas pequenas ofrecen un
incremento en Ia curva de respuesta y generalmente una salida mayor, para un mayor NPS.
Ventajas de las cajas cerradas:
• Cajas pequenas
• Respuesta lineal (plana)
• No hay ruido del orificio
• Capacidad de alta palencia en todas las frecuencias
• Excelentes para Ia calidad del sonido
Cajas con Orificios
Las cajas con orificios solo se diferencian de las cerradas en quese les hace un orificio para
"sintonizarlas." Las cajas recomendadas son disenadas para un gran rendimiento general.
Las cajas grandes tienden a ser faciles de sintonizar en las frecuencias graves,mientras que
medianas y pequefias son mas faciles de sintonizar en las frecuencias mas alias. El diseno
con orificios es deuna respuestamenos lineal queel de Iacaja cerrada, perotierie unasalida
notablementemayor en Ia frecuencia desintonizaci6n.
Ventajas de las cajas con orificios:
• Un pro media de salida mayor que las cerradas
• La frecuencia de sintonizaci6n se ajusta facilmente al cambiar Ia longitud del orificio
• Respuestade bajo profunda con menos exigencia de palencia
• Fabulosas para salida alta con palencia limitada
Construcciiin de una caja
Para un buen funcionamiento las paredes de Ia caja deben ser rigidas y nose deben doblar
cuando sean sometidas a Ia gran presion que ejerce el funcionamiento del altavoz. Recomendamos usar madera comprimidade mediana densidad, de 1.9 em o libra de media densidad. Si Ia caja es muy grande es necessaria reforzarla internamente. Las juntas deben ser
encoladas y aseguradas con tornillos o grapas. lnternamente ios bordes deben ser sellados
con silicona para prevenir las fugas deaire. La cola para madera es Iamejor opci6n.
Calculo deVolumenes
Para calcular el volumen solo se han de medir las dimensiones en centrmetros y aplicar Ia
formula:
Volumen du Ia caja
Alto(cm)xAncho(cm) x Prolundidad(cm)
Dlvidldo por (en litros)
1000
Si dos caras opuestas son de diferente tamafio, slime las y divida el total par dos para obtener el promedio.Usando esta tecnica se ahorrara el calculo par secciones. El espesor del
material con que esta construida Ia caja reduce el volumen interno, de manera que ha de
restarse de las dimensiones exteriores para determinar el volumen interior. La cantidad de
aire queocupa cada modela viene especificado en Ia hoja de caracterfsticas y tam bien debe
sustraerse para obtener el volumen neto interi or.
Configuraciones del cableado
AI variar Ia configuraci6n del cableado de los altavoces, usted puede crear una impedancia
de carga que iguale a su sistema. La alteraci6n de Ia configuraci6n de los cables da una
gama de opciones para impedancia de carga. Las configuraciones en serie, paralela o en
serie-paralela son tecnicas diferentes para el cableado de los altavoces que ofrecen cargas
diferentes. La configuraci6n en serie es un metoda en cadena en el que los altavoces se
conectan depunta a punta. La configuraci6n paralela usa dos o mas altavoces conectados

Empfohlene Gehliuse
DieseAnleitung beschreibt zwei spezifischeTypen von Gehausen, die grundsatzlich verschiedene Performancemerkmale bieten.DieserAbschnitt soli Ihnen dabei helfen zu
entscheiden,welcher der besteTyp fUr lhreAnwendung ist.
Geschlossene Gehause
Geschlossene Gehause lassen sich am leichtesten bauen.Der wichtigsteAspekt beim Bau
eines geschlossenen Gehauses ist zu gewahrleisten, dass es luftdicht ist. DieVerwendung
von Klebstoff und anderen Dichtungsmitteln an allen Fugen gewahrleistet eine solide Konstruktion und verhindert Luftverlust.Das Gehausevolumen wirkt sich unmittelbar auf die Performance des Lautsprechers aus.GroBere Gehause bieten eine flachere Reaktion und tiefere
Basse,wohingegen kleinere Gehause eineAbweichung in der Reaktionskurve bieten und im
Allgemeinen durch hohere Lei stung zu einem hoheren Schalldruckpegel tohren.
Vorteile von geschlossenen Gehiiusen:
• Kleine Gehiiuse
• Lineare (!Iache) Reaktion
• Keine Offnungsgerausche
• Hohe Nennbelastbarkeit in allen Frequenzbereichen
• Ausgezeichnete Klangqualitat
Beliiftete Gehliuse
Be!Oftete Gehause unterscheiden sich von geschlossenen Gehausen nur in sofern. als dass
ein Luftschlitz bzw. eine Offnung hinzugefUgt wird, um das Gehause zu ,stimmen".Die empfohlenen Gehause sind fUr hervorragende Gesamtperformance konstruiert.GrtiBere Gehause
lassen sich in der Regel Ieichter auf niedrigere Frequenzen abstimmen,wohingegen sich mittlere und kleine Gehause Ieichter auf hohere Frequenzen abstimmen lassen.Das be!Uftete
Design zeigt eine weniger lineare Reaktion als das geschlossene Gehause, erbringt jedoch
eine feststellbar hOhere Leistung auf der abgestimmten Frequenz.
Vorteile von beliifteten Gehiiusen:
• Hohere Durchschnittsleistung als geschlossene Geha~se
• Abstimmfrequenz kann Ieicht durch Anderung der Offnungslange a gepasst werden
• Tiefes Bassverhalten bei geringerem Kraftbedarf
• Gut geeignet fOr hohe Leistung bei beschrankter Kraft
Bau des Gehliuses
Um ordnungsgemaB zu funktionieren,mOssen die Gehausewande steif sein und dOrfen nicht
nachgeben,wenn sie dem hohen Druck ausgesetzt sind, der bei Betrieb des Lautsprechers
entsteht. FOr optimale Performance empfehlen wir Faserplatte mittlerer Dichte (Starke ca. 1,9
em) und interneAussteifungen.Das Gehause wird verleimt und mit Nageln oder Schrauben
befestigt.Da Faserplatte luftdurchlassig ist, wird geraten, das Gehause von auBen mit Polyurethan zu behandeln.
Berechnung desVotumens
Zur Berechnung desVolumens einfach die MaBe feststellen und folgende Forme! anwenden:
Gehiiuse-Volumen
Hiihe (em) x Breite (em) xTiele (em)
Vorbei geteilt (Liter)
1000
Sind zwei gegenOber liegende Seiten ungleich lang, die Durchschnittslange der beiden
Seiten berechnen.DasVolumen lass! sich mithilfe dieser Zaht berechnen, ohne das Gehause
inAbschnitten berechnen zu mUssen.Die Starke des Resonanzwandmaterials reduziert das
lnnenvolumen und muss daher zur Feststellung des lnnenvolumens vomAuBenvolumen
subtrahiert werden.Der Lautsprecher selbst reduziert das lnnenvolumen ebenfalls.Die Luftverdrangung fUr jedes Modell ist unterTechnische Daten aufgefUhrt und muss bei der Gesamtkalkulation desVolumens ebenfalls subtrahiert werden.
Verkabelungskonfigurationen
DurchVeranderung derVerkabelungskonfiguration lhrer Lautsprecher konnen Sie eine lmpedanzlast herstellen, die lhrem System entspricht. Bietet dieVeranderung derVerkabelungskonfigurationen eine Reihe von Optionen fOr die lmpedanzlast. Reihen-, Parallel- oder ReihenParallei-Verkabelungen sind verschiedeneTechniken fUr dieVerkabelung von Lautsprechern,
die unterschiedliche Belastungen bieten.Die Reihenkonfiguration ist eine Reihenmethode,
bei der die Lautsprecher von Ende zu Ende verkabelt werden.Die Parallelkonfiguration verwendet mindestens zwei Lautsprecher, die Uber gemeinsameAnsch!Usse verkabelt werden.
Die Rei hen- Parallei-Konfiguration kombiniert beideTechniken.Wahlen Sie das nachfolgende
Verkabelungsdiagramm aus, das der Zahl anTiefttinern und der lmpedanz lhres Verstarkers
entspricht.
Subwoofer-Crossover
Es gibt zwei Betriebstypen fUr Crossover, und zwar passive und aktive. Passive Crossover
(Spulen oder lnduktoren) werden auf den Lautsprecherkabeln zwischen Verstarker und
Lautsprecher platziert. Ein aktives Crossover ist ein elektronischer Filter, der dasAudiosignal
trennt, das verschiedenenVerstarkern zugetuhrt wird. Zur optimalen Subwoofer-Performance
empfehlen wir dieVerwendung von aktiven 80-100 Hz-Niedrigpass-Crossovern bei 12 dB/
Oktav.
Casse acustiche consigliate
II presente manualedescrive agrandi linee due tipi di cassa acustica che forn iscono prestazioni distintamente diverse. La presente sezione mira ad aiutare a deciders quale sia il tipo
migliore per Ia propria applicazione.
Casse a chiusura ermetica
Le casse a chiusura ermetica sana le pili semplici da costruire. La cosa pili importante in
questa tipo di costruzione edi accertarsi che Ia chiusura sia a tenuta d'aria. L:uso di colla
e di un qualche altro tipo di maslice in tutti i punti di giuntura garantira che Ia costruzione
sia salida ed evitera le perdite d'aria. II volume della cassa influira in modo diretto sulle
prestazioni del diffusore. Le casse pili grandi forniranno una risposta pili piatta e bassi pili
profondi, mentre quelle pili piccole presenteranno una gobba nella curva di risposta elorn iran no in generale un'uscita pili alta per un maggiore live! Ia SPL.
Vantaggi delle casse a chiusura ermetica:
• Casse di dimensioni ridotte
• Risposta lineare (piatta)
• Nessun disturbo da apertura
• Gestione di potenza alta atutte le frequenze
• Eccellente qualita del suono
• Ottima uscita di bassa frequenza a confronto delle casse con sfiato
Casse con sfiato
Le casse con sfiato differiscono da quelle a chiusura ermetica solo per il latta che in esse e
praticata un'apertura o porta per "accordare" Iacassa stessa. Lecasse consigliate sono state
progettate per forn ire una buona prestazione nell'insieme. Le casse pili grandi sana generalmente pili facili da accordare alia frequenze pili basse, mentre quelle piccole e di misura
mediana sana pili facili da accordare aile frequenze pili alte. II design con sfiato ha risposta
me no lineare delle casse achi usura ermetica, ma possiede un'uscita notevolmente maggiore
alia frequenza di accordo.
Vantaggi delle casse con sfiato:
• Uscita media superioreaile casse chi use
• La frequenza di accordo puo essere regolata facilmente modificando Ia lunghezza
dell'apertura
• Risposta di bassi profondi con minore potenza
• Ottime per uscita alta con potenza limitata
Costruzione della cassa
Perch8 Ia cassa possa tunzionare in modo corretto enecessaria che le pareti siano rigide e
non si flettano quando sana assoggettate aile aile pressioni prodotte dal diffusore in operazione. Per ottenere i migliori risultati si consiglia di usare MDF (pannello di fibre di densita
media) della spessore di 3/4 di pollice. I pannelli della cassa dovrebbero essere uniti con
colla etenuti assieme in modo sicuro con chiodi o viti.
Calcolo del volume
II calcolo del volume consiste semplicemente nel prendere le misure in pollici e usare Ia
formula seguente:
Volume della casella
Altezza(cm) x Larghezza (em) x Prolonditil (em)
Diviso vicino (nei litri)
1000
Se due Jati hanna lunghezze diverse, sommare i due valori e dividere per due per ottenere il
valore media. II numero cosl ottenuto fornira il volume senza doverlo calcolare dividendo Ia
cassa in sezioni equindi sommando assieme i volumi delle diverse sezioni. Lo spessore del
materiale di diaframma riduce il volume internee quindi Ia si dovra sottrarre aile dimensioni
esterne per calcolare il volume. Anche l'altoparlante vera e proprio riduce il volume interno.
II volume d'aria occupato da ciascun modello eindicato nel foglio dei dati tecnici e dovra
essere sottratto dal volume lordo calcolato.
Configurazione d'impianto
Variandolaconfigurazione d'impianto dei propri diffusori si puo creare un carico d'impedenza
accoppiato a quello del sistema. La modifica della configurazione d'impianto produce una
gamma di scelte di carico d'impedenza Le configurazioni d'impianto in serie, in parallelo, in
