*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 frequency response.

*Can have lower sensitivity than ported enclosures.

*When using high power and small enclosures, the woofer is not in an ideal cooling environment.

*Less low 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 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.
