If you're planning to build your own enclosure and are confused

in what type of enclosure best suits your needs this page will help you

choose what enclosure best fits your needs. There are many different types

of enclosures. The two most common used enclosures are sealed and

vented enclosure. This page will show the advantages and disadvantages

of the two enclosures.

Advantages of a sealed enclosures

*High power handing capability

*Great transient response

*Tolerant of minor enclosure size variation

*Easy to construct

*Smooth rolloff (12dB/octave)

Disadvantages of a sealed enclosures

*Requires a woofer with a long excursion for better low bass

*Can have lower sensitivity than ported enclosures.

*When using high power and small enclosures, the woofer is not in

*Lower bass as compared to a properly tuned vented enclosure

above the ported tuning frequency.

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

*Midrange sound coming from inside the enclosure through the vent

*Loss of cone movement control below vent tuning, which can re
