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.

DESIGN FEATURES
Installation Flexibility - The EXC woofers perform well in smaller­and 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
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
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
Cons

Sealed Band-pass Enclosure
Sealed band­airtight enclosure is built around the front and back of the woofer and one chamber is ported to a specific frequency.
Pros
Cons
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.
within the operating frequencies
Very high output within the range of the operating frequencies
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.
Low power handling beyond the tuning frequency
Poor to moderate transient response
Poor low frequency extension
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's woodworker's glue and Weldwood work 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 Dacron to 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.
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.
