internal dimensions (inch)
enclosures lead to a more enhanced response and higher power handling
whereas larger ones exhibit 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/midbass
response, so you may wish to experiment with various mounting locations
before permanently mounting the woofer.
