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 produce lower bass
because they roll off at 12 dB per/octave. Cone motion is better controlled at all frequencies because of the con-
stant pressure on the back side of the cone. This 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 needs to be sealed tight. If there are any air leaks the woofer cannot function properly because
there is very little force being exerted back on the woofer.
