Model Number: Date of Purchase: 3 Woofer Introduction Audiobahn woofers are a low frequency driver designed primarily for use in smal! 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. Woofer Content Audiobahn Dual 4 Ohm Coil High Excursion Sub Audiobahn Sticker Installation & Owner's Manual Wipe Towel! Registration and Warranty Card Technical Design Features Cast Basket The dual voice coil woofers use a polished chrome aluminum cast basket. This ensures a perfect alignment on each and every woofer. Unlike stamped baskets the cast basket can not bend or tweak under normal play and wear. Rigidity is important when trying to achieve high SPL and loud bass response. Poly Coated Cone The cone material used in the natural excursion sub woofer is spruce pulp paper. This provides а combination of weight and strength and allows high levels of output without cone failure. The spruce pulp paper also provides a very good quality of sound. The cone is non-pressed and has a 2-iayer poly coating which increases the cone rigidity and lowers distortion. Woofer Features Aluminum Voice Coil Former 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 improved power handiing by effectively dissipating heat. Extended Pole Piece 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. | MA № Lis En Woofer Features ee eh Mid A à Le BE Ge EN MN Re Ge ee ES Li Le 2 2 inch Treated Foam Surround The 2 inch treated foam surround is resilient to temperature variations and 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. | Fiat Spider The speakers linear compliance Is balanced through the use of a flat spider design. A flat spider provides symmetrical control of the voice col! 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 durabitity in protective metal finishes. We have spared no expense in this area, and not only is it a protective finish, butitis also a great addition to any plexi style enciosure. 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. ad у | ‚ Ф. - D 2005 Audiobahn Woofer Paramaters > Modei# | AW1000N | AW1200N | AW1500N | | 3 Vas does not represent the volume of a Box.

Fi Enclosures And Setup Building 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 tn 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 Crossover There are two operational types of crossovers, passive and active. Passive crossovers (cails 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. 12 Troubleshooting If 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 iong, they will start to heat up. A) 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. 13 . E | ERE RHEE OS & Warning / Disclaimer шишинишае мА Lois = WE MM EER SH GS td ы x a See eut WARNING Investigate the layout of your automobile thoroughly before drilling or cutting any holes. Take care when you work near the gas tanks, gas lines, hydraulic lines, and electrical wiring. Attach the system securely 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 pinching or damage from nearby objects. The +12V DC power wire must be fused at the battery positive terminal connection. Before making or breaking power connections at the system power terminais, disconnect the +12V wire at the battery end. Confirm your radio/head unit and/or other equipment is turned off while connecting the input jacks and speaker terminals. If you need to replace the power fuse, replace it only with a fuse identical to that supplied with the system. Using a fuse of different type or rating may result in damage to this system which is not covered by the warranty. Disclaimer Specifications are subject to change without notice.

Bi-amping: Means that instead of driving a speaker full-range with a single channel of amplification, through a single set of speaker cables, you actually connect two sets of cables, with each set driven by a separate amplifier, or seperate channels of a multi-channel amplifier. This way, low frequencies and high frequencies each receive dedicated amplification. Bi-wiring: Involves connecting two sets of cables to your speakers, like bi-amping, but both sets of cables connect to the same set of output connectors on your receiver or amplifier. Bi-wiring doesn't deliver more watts to your speakérs, so it doesn't offer the dramatic sonic improvement and higher loudness capability of bi-amping. Bl: Electro-magnetic force factor. BL: Driver motor strength. Boomy: The smearing of transients that makes bass reproduction sound muddled, usually because of improperly designed sealed (too small), ported (to small or tuned improperly), and band-pass enclosures, although the latter are sometimes designed this way on purpose by car audio manufacturers or install shops to be loud. Bridged: In a multi-channel amplifier, the connection of two channels to drive a single load. The input signal is split, and then the phase of one of the signals is inverted. The non inverted signal is sent to the left amplifier and the inverted signal is sent to the right amplifier (L+R-). The load is connected between the two outputs so it receives twice the voltage at a given input level. The resultant power is much greater than the two 4-ohm channels combined.

Dome Tweeter: A high freuency speaker with a dome-shaped diaphragm, usually small in size. Dual Voice Coil (DVC): A voice coil with two windings, generally subwoofers. Each voice coil can be connecied to a stereo channel, or both voice coils can be wired in parallel or series to a single mono channel. If connecting to stereo channels it is important that each channel have the same audio signal input so that 2 channels have the same output and both voice coils work in unison. 14 Driver: A loudspeaker unit, consisting of the electromagnetic components of a speaker, typically a magnet and voice coil. Driver Parameters: The physical properties of a driver that determine it's electrical and acoustical behavior. Also called thiele smali parameters. The minimum parameters used in determing speaker enclosures are Fs, Qts, and Vas.

Dynamic Range: Expressed in decibels, the range of singnal amplitude (from the loudest to the quietest) that can be reproduced effectively by a piece of equipment. With respect tp amplifiers, this range is defined by inherent noise at low levels and by overload distortion at high levels. The higher the number, the better the performance. EBP: Efficiency Bandwidth Product. A rating that helps a builder determine wheather a driver is suitable for a sealed or ported enciosure. EBP of less than 45 indicates the driver should be used in a sealed, 45 - 65 indicates flexible design options, over 65 indicates best for a ported enclosure. This only gives us a general idea what type of box to use. With actual testing the subs, sometimes EBP does not prove 100% accurate. EBP = Fs/Qes. | Efficiency Rating: The loudspeaker parameter that shows the level of sound output when measured at a prescribed distace with a standard level of electrical energy fed into the speaker.

Oscilloscope: An electronic instrument that produces an instantaneous trace on the screen of a cathode-ray tube corresponding to oscillations of voltage and curreni. Out of Phase: When your speakers are wired in reverse polarity (One speaker is wired one way, and another speaker is wired opposite of the first speaker). Bass response will be very thin due to cansellation. Output: The high level (speaker) or line level (RCA) signals sent from one system component to another, or the high level signal from an amplifier to the system speakers. p: Density of air at STP 1.18 kg/m*3 (rho).

Pass Through: To pass a signal through without processing or changing the signal. Passive Crossover: Uses inductors (coils} and capacitors to direct proper frequencies to the appropriate drivers. thes crossover systems can be simple (First Order 1 component @ - 6dB/octave slope) to complex (Fourth Order = 4 components @ -24dB/octave slope). Passive Radiator: A device that looks just like an ordinary driver, except it has no magnet or voice coil. A radiator is usually a highly compliant device, with a similar cone material and surround found on regular active divers. The radiator must usually be at least as large (or larger) providing bass reinforcement for the driver in a similar fashion as any regular ported box. A clear advantage of the radiator is the absense of port noise and some audiophiles claim the radiator provides a better sounding bass than a ported enclosure. Disadvantages include difficulty in tuning and the extra, required baffle area for the radiator. Most radiators can be tuned with either weights or silicone, adding material in a balanced manner until Fb is attained. Pe: Drivers rated RMS power handling capability. Peak: The maximum amplitude of a voltage or current. 18 _ Glossary Phase: Refers the timing relationship of two or more signals or sound waves. It's especially important to be sure that your stereo speakers are playing “in phase." This means that the drivers (cones and domes) of your right and left speakers are moving in and out at the same time. If your speakers are "out of phase" you'll hear significantly less bass, and instead of producing a strong center image, the sound tends to stay localized at the speakers. Phase Coherence: The relationship and timing of sounds that come from different drivers (subs, mids, tweets} mounted in different location in the vehicle. Phase Distortion: A type of audible distortion caused by fime delay between various paris of the signal; can be cause by equalizers. Polarity: The orientation of magnetic or electric fields. The polarity of the incoming audio signal determines the direction of movement of the speaker cone. Must be observed when wiring speakers, so that they are "in phase." Ported Enclosure: A type of speaker enclosure that uses a duct or port to improve efficiency at low frequencies. Excellent design for lower power systems, as the port often adds up to 3dB's to low frequency efficiency. F3 can be set considerably iower with proper design, although low frequency roll-off is generally -24dB/octave. Good transient response with proper tuning, Fb, but source material or frequencies below Fb cause the driver to progressively perform as if it were not enclosed at all. Due to this, ported enclosures without a low frequency filter may have lower power handling compared to other designs. More difficult to property build and tune than a driver. The best way to model these alignments is with a software program, where changes in tuning and enclosure size can be immediately noted. Power (P): The time rate of doing work or the rate at which energy is used. One equation for power Is: Р = Volts*2/Impedance Power Line Capacitor (Capacitor): Wired inline on the power lead with your car amp, this device stores current for instant release when short bursts of energy are needed to produce loud, deep bass notes. Best io mount as close to amp as possible. Pressure effect: In sealed box designs, the pressure build-up on one side of the cone which may cause non-linearity and inhibit dynamic range in the low bass. Push-Pull Configuration: One driver is mounted normally, the second is mounted so that it faces into the enclosure, both sharing the same internal volume and wired out of phase with one another. The drivers are acoustically in phase since they move in the same direction. This alignment theoretically reduces second order harmonic distortion. Q: The magnification of resonance factor of any resonant device or circuit. À driver with a high Q is more resonant than one with a low Q. 19 Qa: The system's Q at Fb, due to absorption losses. Qec: The system's О at (Fc), due to electrical losses. Qes: The electrical Q of the driver. Ql: the system's Q at Fb, due to leakage losses. Qmc: The systems Q at resonance (Fc), due to mechanical losses. Oms: The mechanical Q of the driver. Qp: The system's Q at Fb, due to port issues (turbulence, viscosity, ect.). Qts: The total Q of the driver at Fs, Qts = Qes + Qms. Qtc: Value for the damping provided for a driver in a sealed enclosure. Denotes the enclosures ability to control the driver response at resonance. Qic = 0.707 is the optimum value for sealed enclosures, providing flattest response and highest SPL for deep bass extension. Enclosures for this value are often rather large. Lower Qtc can give even better transition response, down to a Qtc of 0.577 for the best damping and transients, but the enclosure is usually huge and SPL's are down. АСК of 1.0 is a compromise between deep bass and transient response vs. smaller sized enciosure. Larger subs can go with an even higher Qtc, as their resonant frequency is often very low, but Qtc's above 1.5 can begin to sound very muddled and boomy, and sacrifice deep bass extension and transient response for enhanced mid-bass peaks (louder). Ras: Acaustical equivalent of Rms RCA: Also known as line level input, wires carry signals from your source unit to other processors such as an amp, EQ, crossover, line driver, ete. They can also be used from one processor to another. They carry higher signal strength than speaker wires, also known as high-level input. This means that you get a cleaner, stronger signal from unit to unit which helps increase the performance of your stereo. RCA's are the preferred method of wiring. Rear Fill: In autosound, the ambience created by a pair of rear speakers that helps complete the soundstage. A set of high quality components for the front powered by an external amp and a set of coax mounted on the rear deck powered by the head unit or small amp is a good example of a rear fill application. Rear fill speakers should be faded so that they create a richer ambience, but you should not be able to islolate any sounds coming from them. Res: The electrical resistive equivalent of RMS. Resonance: The tendency of an object to vibrate most at a particular frequency. Resonance Frequency: The frequency at which you speaker tends to vibrate most at. 20 ee a es ER CARE en го В 2 E AAA Е we A x A Gal A at . Ka + tea ARA TA па.

The roll-off frequency is usually defined as the frequency where response is reduced by -3dB's. S or (Q'): The overall damping of a 4th order bandpass enclosure. Ье., if you were to figure а 4th order bandpass enclosure with a Qtc of 0.707 for Vr (the sealed chamber), then you would also figure Vf (ported chamber) with an S of 0.707.

Sealed boxes are normally the best enclosure to use for sound quality aplications. Series: A method of wiring that raises the total impedance of multiple voice coils when wired together. Series-Parallel: A method of wiring that contains elements from both wiring methods. Signal: The desired portion of electrical information.

The stage should always appear to be in front of you, with a proper “image” of where each musician is playing on the imaginary soundstage. Spider: The flexible material that supports the former and voice coil within the speaker frame. Standing Wave: A buildup of sound level at a particular frequency that is dependent upon the dimensions of a resonant room, car interior, or enclosure.

Building a slant in a box on the back wall can help reduce standing sound waves. Strontium Magnet: A magnetic material with superior magnetic strength characteristics to that of ferrite. - Subwoofer: A loudspeaker designed to reproduce bass frequencies.
