SELECTING AN ENCLOSURE

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		Cons
∙	Excellent low frequency extension	∙	Lower power handling
∙	Excellent transient response	∙	Low to medium efficiency

∙Uses almost no trunk space

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.

Pros	Cons
∙ Very good low frequency	∙ Medium efficiency
extension

∙Very good transient response

∙High power handling

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.

Pros		Cons
∙ Good low frequency	∙	Low power handling
extension down to the		below the tuning
tuning frequency		frequency
∙ High power handling down	∙	Almost no output
