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.

Woofer Features

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.

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.

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.

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 sealed boxes already include the displacement for the subwoofer. NR = (Not Recommended)

Audiobahn Box Specifications

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

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

ENCLOSURE AND SETUP

Building an Enclosure

To work properly, the walls of the enclosure must be rigid and not ex when subjected to

high pressure generated by the speaker’s operation. For optimum performance, we recom-

mend 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 follow-

ing 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 aver-

age. 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 bafe 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 specica-

tions 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 cal-

culation.

Subwoofer Crossover

There are two operational types of crossovers, passive and active. Passive crossovers

(coils and conductors) are placed on the speaker leads between the amplier and the

speaker. An active crossover is an electronic lter which separates the audio signal fed to

different ampliers. For optimum subwoofer performance, we recommend using an active

80-100Hz low pass crossover at 12/dB/octive.
