Characteristics of Sealed Enclosures
The most basic and simple of all speaker enclosures is the sealed box or acoustic suspension design.
The acoustic suspension design has several advantages; it is easy to build, easy to tune and offers high power
handling, tight response and extended low end output. Acoustic suspension enclosures roll off at 12 dB
per/octave. Cone motion is better controlled at all frequencies because of the constant pressure on the back side
of the cone, which enables you to run more power to the woofer. They are called acoustic suspension enclosures
because the air inside the box acts like a viscous brake to control the woofer. That is why the box
must
be sealed
tight. If there are any air leaks in the enclosure, the woofer cannot function properly.
Pros
1 - High power handling capability
2 - Extended low frequency response and smooth rolloff (12 dB/octave).
3 - Excellent transient response.
4 - Tolerant of minor enclosure size variations.
5 - Easiest enclosure to build.
Cons
1 - Not as efficient as other designs.
