Enclosure Types
The three most common enclosures used in the mobile audio environment
are; s s e e a a l l e e d d , , v v e e n n t t e e d d ( ( p p o o r r t t e e d d ) ) , or b b a a n n d d p p a a s s s s . Each one of these enclosures has
certain characteristics that may or may not suit your needs. In order to
choose the correct enclosure for your system, it will be necessary to
answer a few questions.
One of the most important questions is space. How much area do you
have to work with? Second, you need to know how much power your
amplifier can produce continuously. Next, decide what kind of bass you
want, tight, boomy, punchy, high sound quality, or extreme sound pressure
(SPL). Finally, decide who is going to build your box and if you will be the
wood chuck that does the work, make sure you choose a box that is not
to difficult for your skill level.
When building your enclosure or if you have a professional build it, make
sure the correct materials are used. Ample Audio recommends the use of
Medium Density Fiberboard (MDF) as the primary construction materi-
al, a high grade wood glue, premium pure silicone for sealing seams, solid
wood braces for large or high pressure enclosures, high quality fasteners
for assembly (pre-drilled and screwed for high pressure applications or
heavy gauge nailer brads for less demanding enclosures), high quality
speaker terminals, box filler when applicable, and always make sure that
the mounting area is flat and the woofer hole is the proper diameter.
The easiest type of box to build is a "Sealed Enclosure." Sealed enclosure
offer smaller air space, good power handling at all frequencies, linear
response, and they tend to have exceptional sound quality.
