Sealed enclosure installation
The most basic and simple of all speaker enclosures is the sealed enclosure otherwise referred to as an acoustic suspension
design. They are called acoustic suspension enclosures because the air inside the box acts like a brake to control the woofer.
The sealed
enclosure is the easiest design to build and tune, as long as you work within the minimum and maximum
recommended
volumes you cannot get it wrong. The smaller enclosures produce a tighter punchy bass, the larger enclosures
produce
a deeper bass. Sealed enclosures offer high power handling, tight response and smooth low end roll off and cone
motion
is better controlled at all frequencies because of the constant pressure on the back of the woofer.
Sealed
enclosures are ideally suited to rock, jazz and live music.
Ported enclosure installation
A ported or vented enclosure is not much more complex than a sealed design. It consists of a box with a hole in it.
The vented enclosure has to be correctly designed in order to function correctly. The vent in the enclosure interacts with the air
in the
cabinet and the woofer to increase output and reduce cone excursion at and around the tuning frequency.
At the
tuning frequency of the enclosure almost all of the bass is being produced by the vent, not the woofer. It is more difficult to
achieve
good performance as the enclosure volume and port volume are critical but the results are worth it as the ported box is
up to
3 times as loud as the same woofer in a sealed box. It is also possible with the correct tuning to add a “bump” in the
response of
the enclosure to boost bass at a preferred frequency. Vented enclosures are best suited to dance, R&B,
electronically
produced music and high SPL applications.
