There are several different enclosure designs for different applications.
The EXC subwoofers work very well in all the following enclosure
designs. It is up to you to select the specific enclosure that will work
the best for your particular application.

Infinite Baffle
Infinite baffle is the simplest type of subwoofer installation. In this type of
installation, the woofer(s) is mounted to a baffle, which is then mounted
to either the rear deck or back seat of the vehicle. The best results are
achieved when the trunk area is virtually airtight and isolated from the
passenger compartment.

Pros
•
Excellent low frequency extension
•
Excellent transient response
•
Uses almost no trunk space
Cons
•
Lower power handling
•
Low to medium efficiency
Sealed Enclosure
Sealed enclosures are relatively simple to build and install, as all that is
required is an airtight box. The larger the sealed enclosure, the more the
performance resembles that of an infinite baffle installation.

Vented Enclosure
Vented enclosures use a sealed enclosure with a vent or port in the box
which is tuned to resonate at a specific frequency.
