VENTED ENCLOSURES
VENTED ENCLOSURES
Vented enclosures are not air-tight and incorporate an additional opening known
as a port or vent , which is generally fabricated from either plastic or cardboard
tubing. The port augments the sound coming out of the woofer and is in most
cases capable of going lower in frequency than the same woofer in a sealed box.
Even though vented enclosures are not air-tight , you should follow the same
procedure as with sealed boxes and glue and screw together all joints. Below you
will find drawings for a vented enclosure. In the special case of SEALED enclosures,
volumes greater or smaller than specif i ed can be chosen , with different results.
Smaller enclosures lead to a more enhanced response and higher power handling
whereas larger ones exh i bit better transient and more extended response.

ENCLOSURE CONSTRUCTION
For best performance the walls of the enclosure should be rigid and not vibrate
as a result of the internal pressures generated by the loudspeakers. WET SOUNDS
recommends constructing enclosures from a marine grade plywood like Birch with
a minimum thickness of 3/4 ". In larger enclosures over 1 cubic foot , internal
bracing that joins opposite walls can be incorporated and the final enclosure
should be as rigid as possible . All joints should be glued and fastened with
screws. Additionally , internal joints can be covered with a small bead of silicone
adhesive to ensure that the enclosure is completely air - tight. Drivers should be
fastened to the enclosure with self-threading screws with adequate length and
diameter , utilizing all the mounting holes in the frame. To avoid air leakage, a
foam rubber gasket or similar sealing method should be applied between the
loudspeaker and the enclosure . The external surface of the enclosure may be
painted or fabric - covered , to suit the consumer. Since low frequency sounds are
not directional , subwoofer enclosures can generally be placed anywhere within
the boat , without compromising stereo imaging. However, different placement
locations of subwoofer enclosures can sometimes influence the overall quality of
bass/mid-bass response , so you may wish to experiment with various mounting
locations before permanently mounting the woofer.
