INTRODUCTION

Woofer Introduction

Audiobahn 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 specications in this

manual, our website at www.audiobahn.com. As specications and parameters are subject

to change, we highly advise always checking our website or calling us for the most current

information. By utilizing the latest materials and construction design and techniques, we

are able to offer a sub woofer with optimized low frequency response..

Woofer Specifications

Aluminum Voice Coil Former

The voice coil former is black, anodized aluminum for highly efcient thermal transfer. This

allows winding high temperature copper wire in multiple layers for improved efciency. This

allows improved power handling by effectively dissipating heat.

Extended Pole Piece

The pole piece has been extended to provide a more linear magnetic eld for the opera-

tion 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 bot-

toming out. Additionally, the back plate is vented with a radius aerodynamic back vent

which efciently 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 congured when matched with multiple subs. Please continue to the wiring

diagram portion of this manual for possible congurations you can run. The Natural Sound

subs have a dual 4 ohm voice coil operation.

Woofer Features

Flat Spider

The speaker linear compliance is balanced trough the use of a at spider design. A at spi-

der provides symmetrical control of the voice coil through it’s cone excursion. Linear cone

excursion reduces harmonic distortion for improved sound quality. This allows for reduced

mechanical distortion for better sound quality.

Chrome Finish

Chrome has long been an industry standard in terms of durability in protective metal n-

ishes. We have spared no expense in this area and not only is it a protective nish, but it is

also a great addition to any plexi style enclosure.

Audiobahn Box Specifications

Remember to build your box to the total volume, not just air space, as total volume includes all displacement.

An EBP of less then 45 is SUGGESTED for only a sealed box and greater then 65 for a ported box.

The larger a sealed box is, the lower the sub will play, but the less power it will handle. The smaller a sealed box is,

the higher the frequency the sub will play, and the more power it will handle.

All ports listed are circle ports unless otherwise stated. Surface area of a circle port = (3.14) X (radius) (squared)

Ultimate SPL Bass Box

Everyday Bass Performer

A port velocity of 20% or under is good for everday use and 5% or under for SPL competition . Port velocity

translates to port noise, so the lower the number, the less port noise you will incur.
