SUBWOOFER
CONGRATULATIONS!
You have chosen a superior product for reproducing
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.

DESIGN FEATURES
•Installation Flexibility -The EXC woofers perform well in smaller-
sized sealed, vented
and band-pass enclosures. Regardless of the application, the EXC woofers perform!
•Heavy Cast Aluminum Frame provides extra rigidity and damping with Silver Powder
Coat Finish for durability and scuff resistance.
•Ultra-High power handling Voice Coil with Black Anodized Aluminum Former
increases power handling and performance. Aerospace grade adhesives and
materials insure longevity and high performance.
•High Excursion Design -The EXC woofer offers an Extra Long Voice Coil for extra
high output. New Ultra-Excursion Surround enables this.
•Computer Numerically Controlled (CNC) machined magnet plates and pole piece
precisely focus the magnetic energy for optimum performance. High Emissivity
Coating for improved power handling and lower distortion.
•Vented Pole Piece for greater voice coil cooling.
•Rubber Magnet Cover for added durability and exceptional appearance.
•Custom-designed High Strength Spider controls the long travel cone assembly.
•Gold Plated 8 Gauge Terminals ensure consistently o
utstanding connectivity for cable
hook up.
•Designed and Manufactured in the U.S.A.

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.
Pros
•Very good low frequency
extension
•Very good transient response
•High power handling
Cons
•Medium efficiency
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
•Good low frequency
extension down to the
tuning frequency
•High power handling down
to the tuning frequency
•Higher output than sealed
enclosures
Cons
•Low power handling
below the tuning
frequency
•Almost no output
below the tuning
frequency

Sealed Band-pass Enclosure
Sealed band-
pass enclosures enclose both sides of the woofer(s). An
airtight enclosure is built around the front and back of the woofer and
one chamber is ported to a specific frequency.
Pros
•
High power handling
within the operating
frequencies
•Very high output
within the range of
the operating
frequencies
Cons
•Low power handling
beyond the tuning
frequency
•Poor to moderate
transient response
•Poor low frequency
extension
C
ALCULATING NET INTERNAL ENCLOSURE VOLUMES
When constructing any type of enclosure, you must be aware that the
outside dimensions DO NOT represent the true (Net) volume inside.
Such things as woofers, ports, thickness of enclosure material, dividing
walls, and any internal bracing will reduce the total amount of the actual
air space available. The following worksheet has been designed to
provide you with the necessary steps to accurately calculate the absolute
(Net) internal volume of any given enclosure.
Calculating Cylindrical Port Volume
1. Measure the outside diameter of the port and divide by 2 for the
radius.
2. Square the radius and multiply by 3.14 (pi) to arrive at outside port
area.
3. Multiply the area by the length of
the port inside the enclosure for the
port volume.

BUILDING THE ENCLOSURE
•Determine the dimensions of your enclosure.
•Be certain the box you have designed will fit into the location you
have chosen. Sometimes making a cardboard box with the same
outside dimensions is helpful.
•Use 3/4 inch thick Medium Density Fiberboard (MDF) or High
Density Particleboard. It is preferable to cut the wood with a table
saw to ensure straight, even joints. If a table saw is not available,
a circular saw is acceptable.
•Use a "T' square to verify precise right angle gluing.
•Use a high quality wood glue and air nails or wood screws to
assemble the enclosure. Elmer'swoodworker's glue and
Weldwoodwork well. To guarantee an airtight box, seal each
inside joint with silicone sealant.
•For Sealed Enclosures, stuff the chamber with 50-75% filling
(approximately 1.5 pounds per cubic foot) of fiberglass insulation
or Dacron.
•For Vented Enclosures, staple 1-inch thick fiberglass insulation or
Dacronto all walls of the enclosure except the baffle to which
the woofer is mounted.
•Use the eight (8) wood screws or T-nuts and bolts to seal the
woofer in the enclosure. Progressively tighten each of the bolts or
screws to prevent warping the woofer frame.
