Orion Car Audio HCCA 15.2 - Manual (Page 17)

ENCLOSURE DESIGN
This section gives the basic description for a sealed enclosure. Orion HCCA woofers
are designed for sealed enclosures and vented enclosures. Sealed enclosures are
generally considered the most versatile for all music types and are the easiest to
build. They will also give high power handling with a wider range of frequencies.
The enclosure must be absolutely air tight. Use a high quality wood glue for all
seams of the enclosure. The enclosure should also be screwed together. The
enclosure should be no less than 3/4" on sides. The baffle board (woofer mounting
plate) should be no less than 1". If the woofer mounting is to be recessed then a
minimum of two 3/4" plates together should be used. As MDF is a porous material
it is best to also seal the inside of the enclosure.
NOTE: The woofer must face up or down only, especially in sealed enclosures.
NOTE: Refer to the website www.orioncaraudio.com for updated enclosure
data for your woofer application.
