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. Woofer Audiobahn Dual 4 Ohm Coil High Excursion Sub Audiobahn Sticker Installation & Owner's Manual Wipe Towel Registration and Warranty Card 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. WWW.DUBSERIES.COM 03 Woofer Features 2 inch Rubber Surround The 2 inch rubber surround provides the consistent support necessary for the linear motion of the speaker cone. In addition, the inherent damping capabilities eliminates the transmission of sonic disturbances between the cone and the frame of the speaker. This greatly improves the clarity of the speakers frequency response. Flat Spider The speakers linear compliance is balanced through the use of a flat spider design. A flat spider 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 finishes. We have spared no expense in this area, and not only is it a protective finish, but it is also a great addition to any plexi style enclosure. Convex Dust Cap The use of a convex dust cap is used to increase the cone rigidity and improve power handling by forcing more air through the voice coil. Added benefits include smooth frequency response. 04 Woofer Features Aluminum 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. pport In e nd the of the 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. e use cal Linear ed rtion 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. no h, but it 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.

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 sho ...
