Custom Car Audio Boxes - Subwoofer Enclosures
When utilizing the Infinite baffle
front cone is isolated from the rear cone when
mounted on the "baffle board".
The baffle board is the board that the woofer is
Advantages of this design include
simplicity, minimal occupation of space.
Disadvantages of this design are larger power
requirement, difficulty (sometimes extreme) in
completely isolating the two sides of the cone from
each other, and slightly less accurate sound
As with any
speaker box design there are disadvantages and advantages
of design type.
Unfortunately, there are several disadvantages to the
infinite baffle. When a speaker is mounted in an enclosure,
the air inside the enclosure acts like a spring against the
speaker cone, and the resulting buildup in pressure provides
mechanical damping and prevents excessive cone movement. But
an infinite-baffle installation does not use an enclosure,
so the mechanical damping is poor, resulting in "hang-over"
and lack of definition. The power handling of the speaker
will also be compromised since the infinite baffle provides
very little control over cone excursion.
When utilizing the
infinite baffle design, the woofers
front cone is isolated from the rear cone when mounted on
the "baffle board". This basically uses the vehicle as a
box. If you elect to use this design, make sure you
purchased the correct type woofers and, as each woofer
has its own designed function.
as mentioned there are many
woofer speakers on the market. They're many
speakers available for infinite baffle or "free air"
applications of available, usually the biggest difference
from free air speakers and sealed box speakers is of the
"stiffness" or spring action of the speaker cone.
cone stiffness is simply, how easy it is to move the
speaker cone back and forth. In a sealed box enclosure,
woofer cone movement is controlled by the air tight seal. This seal will control speaker cone movement.
