INSTALLATION GUIDE

true high fidelity in the car. This precision component, when properly
installed, is capable of audiophile-quality performance. The EXC 8,10 and
12 woofers are well suited for sealed, vented, and sealed band-pass
enclosures. They also work well in infinite baffle installations at one-half the
power rating.

Should your woofer ever require service or replacement, recording the
information below for your own records will help protect your investment.

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

• Lower power handling

• Low to medium efficiency

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

• Very good low frequency

• Medium efficiency

Cons

extension

• Very good transient response

• High power handling

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

Pros

• Good low frequency
extension down to the
tuning frequency

• High power handling down
to the tuning frequency

• Higher output than sealed

• Low power handling

• Almost no output
