PRACTICE SAFE SOUND™
Continuous exposure to sound pressure levels over 100dB may cause permanent
hearing loss. High powered automotive sound systems can generate sound pressure
levels in excess of 130dB. When playing your system at high levels, please use hearing
protection and prevent long term exposure.
Included in this box are all the necessary mounting hardware and cables for your basic
installation. Listed below is a detailed list of the components included in this system
package.

TOOLS OF THE TRADE
Listed are the majority of the tools required to perform the installation. Having the
proper tools will make the installation much easier. It is very difficult when you get
half way through the installation and discover that you require a specific tool to
get yourself through a particular part of the installation. Some of these tools are
necessities. Some make the job much easier.
• Marking Pen • Electric Drill and assorted Bits
• Phillips Screwdriver • Wire Strippers
• Allen Wrenches • Volt/Ohm Meter (Optional)
• Table Saw • Jig Saw
• Wire Cutters • Wire Crimpers
INSTALLATION
The performance of these XTRPRO subwoofers is directly proportional to the quality
of the installation. Care taken with the installation process will be rewarded by years
of satisfying performance. If you are unsure of your installation abilities, please
refer to your local authorized ORION dealer for assistance. Orion dealers are trained
professionals dedicated to extracting the maximum performance out of your Orion
system. If you decide to install this speaker system yourself, please read the entire
section on sealed and vented enclosures before starting the installation.
FINDING SPEAKER MOUNTING LOCATIONS
Choosing the correct speaker locations will have the greatest effect on the sound
quality of the system. Different considerations are needed when choosing the
locations that best suit your needs. The locations must be large enough for the
speakers to fit. Care is needed to ensure that the location you have chosen will not
affect any of the mechanical or electrical operations of the vehicle.
Determining the best location for the speakers will depend on your cosmetic needs
and your vehicle’s interior. Usually the woofers are installed in the trunk, rear seat, or
rear of the vehicle..

are calculated into the volume of the enclosure, you will not need to add these
volumes to calculate GROSS volume for the enclosure.
Notes
* Due to the high power capabilities and long excursion of the XTRPRO woofers, the
Thiele/Small Parameters were calculated and measured using a Klippel analyzer
system.
** Energy Bandwidth Product (EBP) is determined by the following formula Fs/
Qes=EBP. EBP values of 50 and lower suggest a sealed enclosure is best, 50 to90
means the subwoofers versatile and 90 and above mean vented Enclosure is
recommended.
*** Subsonic filter should always be used and adjusted specifically for vented box
There are many different factors that help determine the best style of enclosure for
you or your vehicle. Listed below are some factors that should be considered.
The size of the enclosure is directly proportional to the efficiency and power handling
of that speaker. A woofer in a smaller enclosure will handle more power than the
same woofer in a larger enclosure. The exact opposite is true for efficiency, a larger
enclosure will play lower frequencies at a louder volume with less power than a
smaller enclosure.
The following will explain differences in sealed enclosures. A large enclosure is
best suited if you have smaller amounts of power (25% to 50% of speaker’s power
handling), have a larger vehicle or looking for greater output. While the smaller
enclosure should be utilized if you have recommended power (50% to 100% of
speaker’s rated power handling), have a smaller (high gain) vehicle or are looking for
more accurate sound reproduction. A smaller sealed enclosure will yield more control,
this audible translates into faster and more accurate bass.
A vented enclosure will offer greater efficiency and stronger low bass output compared
to a sealed design. A vented enclosure uses the back wave (sound from the back side
of the cone) to reinforce the output from the speaker. A properly tuned enclosure will
yield gain across the entire bandwidth of the subwoofer system and offer more cone
control than a sealed enclosure. A low tuning will yield less overall gain but greater
extension (low bass). A high tuned enclosure will offer more gain but limit the low
end response of the system. One of the advantages of having a vented enclosure is
because it is tunable to a specific frequency and that tuning frequency is known as the
“Fb”. Another important box specification is “F3”, which is the roll-off frequency at
which the driver's response is down -3dB. This is an important number when it comes
to setting your high-pass filter or your ORION Intelli-Q. The Intelli-Q should be set at
the same frequency as the “F3”as this will keep the speaker from damaging or what
is know as over-loading.
Good planning and proper construction will assure the best response from your
system. The next pages will outline many different enclosures and designs that allow
the XTRPRO subwoofers to perform best. As always, if you have any questions on
enclosure construction or design, call Technical Support 1-800-753-0800.
