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
