Woofer Introduction

AAudiobahn woofers are a low frequency driver designed primarily for use in
small sealed or vented enclosures depending on the model of sub. Please check
the specifications in this manual, our website at www.audiobahninc.com , or call us
at 714-988-0400 or 800-488-8595. As specifications and parameters are subject to
change, we highly advise always checking our web site or calling us for the most
current information. By utilizing the latest materials and construction design
and techniques, we are able to offer a subwoofer with optimized low frequency
response.

Technical Design Features

Cast

The dual voice coil woofers use a polished chrome steel stamped basket. This
ensures a perfect alignment on each and every woofer.

Glass Fiber Composite Laminated

The cone material is a KM3 Coated laminated paper. This provides the necessary
combination of weight and strength and allows for extreme levels of output
without causing cone failure. The increased rigidity of the cone also helps lower
distortion levels.

The 2 inch rubber surround prov id es t he c on si st ent support
necessary for the linear m o ti on o f th e sp ea ke r co ne . In
addition, the inheren t da mp in g ca pa bi li ties eliminates the
transmission of sonic disturbances between the cone and the
frame of the speaker. This greatly improves the clarity of the
speakers frequency re sp on se .

Woofer Features

AAluminum Voice Coil

The voice coil former is black, anodized aluminum for highly
efficient thermal transfer. This allows winding high temperature
copper wire in multiple layers for improved efficiency. This allows
for improved power handling by effectively dissipating heat.

Extended Pole

The pole piece has been extended to provide a more linear magnetic
field for the operation of the woofer. This lowers distortion and
provides the woofer with better low frequency response.

Vented Oversized Back Plate

The back plate has been stepped deeper to allow the woofer more
excursion without bottoming out. Additionally, the back plate is vented
with a radius aerodynamic back vent which efficiently and quickly
circulates cool air around the voice coil. This allows for more
excursion and higher power handling without damaging the sub.

Voice Coil

The 4-layer, edge wound voice coil design of the speaker allows for
a variety of impedance loads to be configured when used individually
or matched with multiple subs. Please continue to the TECH TIPS
section of this manual for wiring diagrams and procedures. The High
Excursion subwoofers are a dual 4 ohm voice coil configuration..

Enclosure and Setup

BBuilding an Enclosure

To work properly, the walls of the enclosure must be rigid and not
flex when subjected to high pressure generated by the speaker's
operation. For optimum performance, we recommend using 3/4" MDF
(Medium Density Fiberboard) and internal bracing. The enclosure
should be glued together along with support of screws or nails.
Because MDF is porous, it is suggested that you seal the outside with
polyurethane prior to painting or carpeting.

Calculating Volume

Calculating is merely a matter of measuring the dimensions in inches,
and using the following formula:

Box Volume = (Height) x (Width) x (Depth) divided by 1728. This will give
you the volume of the box in cubic feet.

If two facing sides are uneven length, add them together, and divide
by 2 to take the average. Using this number will give you the volume
without the necessity of calculating the box in sections, and adding
the sections together. The thickness of the baffle material reduces
the internal volume so this must be subtracted from the outside
dimensions to determine the internal volume. The amount of air
displaced by each model is listed on the specifications sheet in this
manual and should also be subtracted from the gross volume
calculation. All box parameters include displacement for ports and
subs. These specs do not include the volume of the material used to
build the box, so this must still be factored into the calculation.

Subwoofer

There are two operational types of crossovers, passive and active.
Passive crossovers (coils and conductors) are placed on the speaker
leads between the amplifier and the speaker. An active crossover is an
electronic filter which separates the audio signal fed to different
amplifiers. For optimum subwoofer performance, we recommend using an
active 80-100Hz low pass crossover at 12dB/octive.

Troubleshooting

IIf you start having problems with distorted
sound or loss performance after installing your
subs, you can follow the instructions below to
try and locate what is causing the problem.

1) If you have any distorted sound, loss of
performance, or rattling from your subs, check
the connections running from your amplifier or
other processor to the box. You will also want to
check the connections inside the box to make sure
no wires have become unhooked or are loose.

2) If the above does not solve the problem,
check your enclosure thoroughly to see if there
are any leaks, cracks, or broken pieces. Any loss
of structural integrity of your enclosure can
cause significant performance loss and distortion.

3) The next step you can take is to remove
the subs and look for any burned wire leads or
separated components. You can normally smell
something burning when a sub blows or is going
bad. Sometimes when you play subs to hard for
too long, they will start to heat up.

4) If none of the above steps solve the
problem, you will want to start looking at the
other components in the vehicle. Start by
checking all connections to and from the box,
amplifier, source unit, or any other processors
you may be using. You will need to reference to
that particular manufacturer for any setting
configurations or troubleshooting.

Warning and Disclaimer

WWARNING

Investigate the layout of your automobile thoroughly before
drilling or cutting any holes to the automobile. Take much care
when you work near or around the gas lines, hydraulic lines, and
electrical wiring. Do not use a power amplifier unmounted and
make sure to secure the entire system to the automobile to
prevent damage, particularly in the event of an accident. Do not
mount the system so that the wire connections are unprotected
or are subject to pincing or damage from nearby objects.

The +12V DC power wire must be fused at the battery positive
terminal connection.(16" max. distance is recommended) Before
making or breaking power connections at the system power
terminals, disconnect the +12V wire at the battery end. If you need
to replace any power fuses, make sure to replace the fuse with the
exact same size rating. Using a different type or rating may result
in damage to this system which is not covered by the warranty.
