OSURE DESIGN
This sect
ion 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
