Thank you and Congratulations,
Congratulations on your decision to purchase PowerBass Xtreme “2XL” series subwoofers.  These top-of-the-line speakers are the result of years of extensive engineering and testing, resulting in the finest car audio subwoofers you can purchase today.

At PowerBass USA, Inc. we are confident you will have many years of outstanding enjoyment from your investment.  For maximum performance we recommend that you have your new PowerBass Xtreme product installed by an Authorized PowerBass Xtreme Dealer. Doing so will also automatically extend your warranty to a full THREE-YEAR Period. 

POWERBASS XTREME 2XL WOOFER FEATURES

• IMFPM Cone: A new material designed for high powered/high pressure environments in which a FP Matrix “Foam Sandwich” was created to provide a very rigid and stable surface that will prevent cone krumpling while increasing bass response.
• Custom Aluminum Basket with Voice Coil Perimeter Aerovents: 
  This cast aluminum basket is manufactured to the highest quality standards to ensure maximum excursion, exceptional alignment of the subwoofer’s motor structure and moving parts while providing an extremely rigid, non-resonant frame.
• Pro-Lock Input Terminals:  Giving your woofer all of the current and voltage that it needs to perform up to maximum capability is why we have designed these Pro-Lock terminals. They insure a tight and energy efficient connection between your amplifier and the woofers voice coil. They also simplify wiring in multiple speaker installations.
• Vented BKSV Voice Coil Former with Bonder 360 Adhesive: These specially designed Kapton™ coils are coated with Hernon® Bonder 360 to provide a thermal shock resistant bond that can withstand temperatures of 600˚F (316˚C).  This dramatically increases heat dissipation and increases power handling.
• Xtra Xtra Large Motor Structure: Just like a cars’ engine, the motor structure of a woofer drives the cone. This dual stack motor will allow your 2XL woofer to handle lots of power while delivering accurate linear movement for tight deep bass.
• Custom Billet Aluminum Trim Ring: Clamps the surround for a better grip on the frame by holding it in-between the ring and frame.  This ensures the surround will stay in place during high excursion of the  woofer cone.
• U-turn High Roll Santoprene Surround: This high roll surround is used to ensure long and linear travel throughout the entire excursion range resulting in more bass output and higher SPL. The nonstandard "U" design also gives the woofer more cone area to move more air and make more bass. 

WIRING GUIDELINES

It is highly recommended that you seek an authorized PowerBass dealer to properly setup, wire and install your woofers for maximum performance. 
All PowerBass Xtreme subwoofers use dual voice coils. The use of dual voice coils offers you more versatility in system configuration.  It is important to know the limits of your amplifier to optimize its performance.  It is always better to use your subwoofer in a mono / bridged mode if your amplifier has the capabilities.  There are basically four different types of wiring configurations: Series, Parallel, Series-Parallel or Parallel-Parallel.  It is possible to change the impedance or load by how the speakers are to be wired and by the quantity of woofers used.

DUAL VOICE COIL WIRING

NOTE: Never connect only one coil of a Dual Voice Coil (DVC) speaker. BOTH voice coils must be connected to the amplifier

INSTALLATION EXPERIENCE

Installation of PowerBass Xtreme Speakers requires experience with a variety of mechanical and electrical procedures. This manual provides only general installation and operation instructions. If you have any reser-vations about your installation skills or lack of the proper tools, please contact your local PowerBass Xtreme dealer for assistance. 

CHOOSING A SPEAKER ENCLOSURE

The PowerBass Xtreme 2XL Subwoofers are engineered to perform at their optimum level in a Sealed en-closure.  However, while not optimum, these woofers may also be used in vented and bandpass enclosures.  For maximum performance we recommend you have your new PowerBass Xtreme Subwoofer installed by an Authorized PowerBass Xtreme Dealer.

SEALED BOX

A sealed or acoustic suspension enclosure is easy to build and typi-cally offers a smaller size enclosure and greater power handling. It has the most predictable frequency and phase response; the bass response will roll off slower than that of a ported design. Sealed boxes typically provide the best musical detail and definition. A well-designed sealed enclosure will exhibit smooth frequency response with excellent sound quality and great low bass extension.  They also exhibit relatively accurate, punchy bass reproduction for most types of music. If a sealed enclosure is too large to fit into a specific area of a vehicle, it is possible to decrease the recommended box volume by using 1.5 pounds per cubic feet of low density, high heat specific box stuffing material.  PowerBass recommends Fiberglass, Dacron, Poly-Fill or long fiber wool for stuffing the enclosure.  (Decreasing the box enclosure however should not exceed 20% of the recommended size.)  When using any type of box stuffing mate-rial be sure that the subwoofer’s vented pole piece is clear from any obstructions, since covering the pole piece will result in loss of bass and can possibly cause damage to your subwoofer.   The most important aspect of a sealed enclosure is to make sure that it is airtight and solid. If your enclosure has any air leaks or if the panels vibrate or flex, you will experience a loss of bass output. Using glue and some type of sealant (caulk) on all seams will ensure a solid constructed box without any air leaks.

VENTED BOX 

Also known as a ported or bass reflex enclosure, this type of box is almost as easy to construct as a sealed enclosure. This design however is more efficient and results in an increase of bass output at certain frequencies. Although vented enclosure has an output advantage at some frequencies, it also has a steeper rolloff, which will only affect bass frequencies below port tuning. Air inside the port will move in phase with the subwoofer reinforcing frequencies above the F3 (-3dB point). The SPL advantage of the vented enclosure comes from the fact that the effect of the vent tuning reduces the excursion of the subwoofer near the tuning frequency allowing more SPL to be produced before the subwoofer bottoms. Damping material should also be used to line the internal walls to reduce any sonic reflection. Because of the characteristics of a vented enclosure, subwoofers typically will become unloaded (act as if it is not in a box) at frequencies of ½ octave below the enclosure tuning frequency. Using a high pass filter / subsonic filter will help prevent the subwoofer from unloading or exceeding its excursion capabilities. It is important to stay within the recommended enclosure specifications. (PowerBass recommends port placement to coincide on the same panel or baffle that the subwoofer resides on.

PREPARING FOR INSTALLATION

NOTE: The tools listed below may be required for basic installation.

• An electric drill with bits
• Saber, circular and jig saw
• Phillips-head and standard screwdrivers
• Wire strippers
• Crimping tool and needle-nose pliers
• Silicone sealant (for enclosures), closed cell weather-stripping (for the speakers)

INSTALLATION PRECAUTIONS

NOTE: Proceed only if you are a qualified installer otherwise; let your dealer do it.

• Always wear protective eyewear when using tools.
• Turn off all stereo and other electrical devices before you begin.
• Disconnect the (-) negative lead from your vehicle’s battery.
• Keep the speakers in the package until final installation, and always rest it with the cone facing up. Never use force when installing a speaker.
• Locate all fuel lines, brake lines, oil lines, and electrical cables when planning your installation.
• Check to see if there is enough clearance behind the mounting surface before drilling holes or install-ing screws for proper speaker ventilation. 
• Also make sure there’s enough front clearance for speaker cone excursion. Failure to do this could cause the cone to vibrate against any obstructing object.
• Use a utility knife to trim away fabric from the speaker mounting hole location before drilling.  It is hard to get a good seal if you have both the carpet & subwoofer gasket between the speaker and the enclosure.
• When running speaker wires through sheet metal, be sure to use grommets to properly insulate the wires from metal edges.

BANDPASS ENCLOSURE

The most common bandpass enclosure is a combination of a sealed and a vented enclosure working together (4th order or single reflex bandpass system). The rear of the speaker goes into the sealed chamber while the front of the speaker goes into the vented chamber. Because the vent produces all the sound generated from this type of enclosure, sound quality may not be as good as a well-designed ported or sealed design. Often the sacrifice for sound quality and subwoofer cone control is greater SPL output. However unlike a sealed or vented enclosure, you can effectively in-crease the enclosure sensitivity with the appropriate tuning choices.  You can choose to design a narrow frequency band with very high sensitivity or choose a wide frequency band with the sacrifice of lower sensitivity. The damping effect of the vented chamber reduces the motion of the cone so that potentially higher sound output is achieved without the subwoofer reaching its mechanical limits.  Minor deviations from design recommendations however may result in frequency response and distortion problems.

(If you are intending to use multiple subwoofers in your system, PowerBass recommends hav-ing separate chambers for each subwoofer if the subwoofers will be operated by two different amplified signals.  This will prevent any possible cancellation.)
NOTE: Due to the vented backplate, you must allow an additional 2" behind the subwoofer when designing your speaker enclosure.

ENCLOSURE VOLUME

To calculate the volume required for your enclosure please refer to the Recommended Enclosures section of this guide for your specific model number. These are listed in both cubic fee  and liters. One cubic foot is expressed as 12" x 12" x 12" = 1728 cubic inches (see picture below).

TIPS TO GET THE MOST OUT OF YOUR 2XL WOOFER
Your PowerBass Xtreme subwoofer has been meticulous engineered and designed to handle high power musical reproduction.  Despite their rugged construction, it is possible to damage your speaker if they are improperly used.  In general, you will hear distortion as a so-called warning before any damage occurs.  If you hear distortion in your system, immediately reduce the musical level to the point where the sound retains its clarity.

1. All PowerBass Xtreme subwoofers require an initial break-in period before it will reach optimum performance. Like any new precision machinery, allow a minimum of several days to one week with normal daily usage to ensure that the suspension has properly been broken-in. 
2. Never use only one coil on a dual voice coil subwoofer. Doing so will significantly decrease the ef-ficiency and power handling of the speaker.
3. Be sure you supply the speakers with enough unclipped amplifier power to drive them properly.(More damage can be done to a speaker by under-powering and clipping your amplifier than any other way!)
4. Where possible, run your Speakers in mono instead of stereo.  Most bass is reproduced in mono so there is less chance of any cancellation if played in mono.
5. Where possible, wire your Speakers in parallel instead of series.  Bass is reproduced either way but again there is less chance of cancellation in parallel.  
   NOTE: Be sure the amplifier you are using is stable to the resulting impedance of the speaker load!
6. Where possible, a separate amplifier just for your subwoofers should be used with an electronic crossover to set the frequency range.
7. Do not block the front of your speakers or ports.  You want as much direct air coupling as possible. Also be sure to round off the inside edges of the port to reduce any port noise.
8. For ported enclosures, keep in mind that you must leave at least twice the port diameter size be-tween the subwoofer and the port itself.  Leave at least one time the port diameter between the port and any walls of the enclosure.
9. Remember the Golden Rule “Measure twice…cut once.”

PARAMETERS FOR POWERBASS 2XL SERIES SUBWOOFER

(Due to Constant Improvements, Specifications and Parameters are subject to change without notice.)

POWER RECOMMENDATIONS

Many speaker and amplifier brands measure their power ratings in different ways.  Often the stated “Max Power handling” are viewed as continuous RMS power handling of the speaker, when actually the “Max” is generally the breaking point of the speaker.
In an effort to minimize any confusion, PowerBass has chosen to rate our Super Subs in the following manner:
NOMINAL POWER HANDLING
Playing your woofer at levels below the Pe-RMS spec will allow the woofer to operate at optimum conditions and cause the speaker minimal mechanical degradation over time.
Pe-RMS POWER HANDLING
Pe-RMS is the highest power rating we assign the woofer for continuous use under normal conditions.  Exceeding this power level for extended durations will result in mechanical degradation that may lead to possible failure over time.
Pe-MAXIMUM POWER HANDLING
Pe-Maximum is the maximum power rating the woofer can handle for short bursts or peak transients with clean input power.  Exceeding this power level or using dirty (distorted input power) will cause thermal failure that will void the speaker warranty.

RECOMMENDED ENCLOSURES

Please note that these enclosure volume recommendations are for the internal airspace inside the enclo-sure and include the displacement of the subwoofer and ports. When choosing your enclosure type, please pay close attention to your specific woofer, failing to use the correct enclosure may result in lower power handling and poor sound quality.   To calculate the internal airspace required, take the internal dimensions of the box. First multiple these number by themselves and then divide this sum by 1728.  (W x H x D) / 1728. Please contact your authorized PowerBass Autsound dealer for other designs and specifications. (Even though these subwoofers can be used in a ported enclosure, PowerBass recommends a sealed enclosure for optimum performance and sound quality.)
