*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 because of the resonant effect of the vent tun

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 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 ven
