If you're planning to build your own enclosure and you wonder what type of
enclosure best suits your needs this page will help you choose the correct
I
enclosure. There are many different types of enclosures. The two most
L
common used enclosures are sealed and vented enclosures. This page will
D
show the advantages and disadvantages of the two enclosures.
I
N
Advantages of a sealed enclosure
G
*High power handling capability
*Great transient response
A
*Tolerant of minor enclosure size variation
N
*Easy to construct
*Smooth rolloff (12dB/octave)
E
N
Disadvantages of a sealed enclosure
C
*Requires a woofer with a long excursion for better low bass frequency
L
response.
O
*Can have lower sensitivity than ported enclosures.
S
*When using high power and small enclosures, the woofer is not in an ideal
cooling environment.
U
*Less low bass as compared to a properly tuned vented enclosure above
R
the ported tuning frequency.
E
Advantages of a vented enclosure
*Increased output around vented tuning
*Higher power handling above the port tuning frequency
*Extended frequency response
*Magnet is in a good cooling environment
*Handles higher bass frequencies with less distortion
Disadvantages of a vented enclosure
*Vented enclosure transient response is not as good as sealed boxes be-
cause of the resonant effect of the vent tuning
*Midrange sound coming from inside the enclosure through the vent
can produce unpleasant sound coloration.
*Loss of cone movement control below vent tuning, which can result in high
distortion and mechanical failure of the driver.
*Lower power handling below the port tuning frequency.
