Calculating Box Volume:
Measure the dimensions and use the
following formula.
• Para calcular el volumen sólo se han
de medix las deminsiones y aplicar la
fórmula.
• On calcule le volume en mesurant la
dimension de chaque côté et en utilas
ant la formule suivante.
• Zur Volumen-Berechung benötigen sie
die genauen Maße und Dimensionen.
• Calcolare il volume é essenzialmente
solo un problema di misurazione delle
dimensioni della cassa e di appli
cazione della formula.
(H” x W” x D”) ÷ 1728 = cu. ft.
or (H x W x D cm) x .001 = liters
When you know the required volume and
two dimensions of the box, use the following formula to calculate the third
dimension.
• Lorsque vous connaissez le volume
requis et deux des dimensions du boîti
er, calculez la troisième dimension à
l'aide de la formule suivante.
• Wenn Ihnen das erforderliche Volumen
und zwei Boxenabmessungen bekannt
sind, können Sie die dritte Abmessung mit der folgenden Formel errechnen.
• Quando si conosce il volume necessario e le due dimensioni della cassa, usare la formula seguente per
calcolare la terza dimensione.
• Cuando sepa el volumen requerido y las dos dimensiones de la caja, use la siguiente fórmula para calcular
la tercera dimensión.
(cu. in.) ÷ (W” x H”) = Depth” or (cu. cm) ÷ (W x H cm) = Depth cm
*Filled Enclosures – Whenever possible, and when a smaller total box volume is desired, we recommend loosely filling the
enclosure with Dacron or fiberglass insulation. By doing so, the volume of the box may be reduced 20 – 30% yielding the
same damping (Qtc) performance characteristics as the larger “unfilled” enclosure. The entire enclosure should be “loosely”
filled up to the magnet structure of the subwoofer. DO NOT PACK the enclosure or place the filling such that it obstructs the
movement of the cone as this can negate the positive effects of the filling.
**Unfilled Enclosures - For applications such as Plexiglas enclosures where the interior of the box will be visible in the installation, the optimum “unfilled” box volumes have been provided for your convenience.
Please note these types of applicationss will require a slightly larger total volume then the “filled” enclosures.
