NCLOSURES
This manual outlines two specific types of enclosures
that provide distinctly different performance. This
section is to help you decide which type is best for
your application.
SEALED ENCLOSURES
Sealed enclosures are the simplest to build. The most
important part of building a sealed enclosure is to make
sure that the enclosure is airtight. Using glue and some
type of sealant on all seams will ensure solid
construction and prevent air leaks. The box volume will
directly impact the performance of the speaker. Larger
enclosures will provide flatter response and deeper bass
where smaller boxes will provide a bump in the
response curve and generally higher output for greater
SPL.
Advantages of sealed enclosures:
•
Small enclosures
•
Linear (Flat) response
•
No port noise
•
High power handling at all
frequencies
•
Excellent for sound quality
VENTED ENCLOSURES
Vented enclosures vary only from the sealed enclosure
in that a vent or port is added to “tune” the enclosure.
The enclosures recommended are designed for great
overall performance. Larger boxes tend to be easy to
tune to lower frequencies while medium and small
boxes are easier to tune to higher frequencies. The
vented design is less linear in response than the
sealed box but with noticeably more output at the
tuning frequency.
Advantages of vented enclosures:
•
Higher average output than sealed
•
Tuning frequency can be easily adjusted by
changing port length
•
Deep bass response with lower power
requirements
•
Great for high output with limited power
