GRAND TOURING SERIES TM Automotive Subwoofers P - 8 0 0 , P - 10 0 0 , P - 12 0 0 , P - 15 0 0 O w n e r ' s M a n ua l GENUINE JBL 02 Thank you for choosing this JBL Power Series subwoofer. The Power Series of automotive subwoofers is designed to be used in modern car audio systems to produce extended, powerful bass in a limited amount of space. Power Series subwoofers are designed to suit a broad range of applications and can be used in a wide variety of enclosure types. In order to maximize the performance potential of these subwoofers, it is recommended that installation be left to a qualified professional. If you feel you have the ability to properly build an enclosure and install the subwoofer yourself, the information in this manual will help you get it right. Keep your sales receipt with this manual in a safe place so both are available for future reference. JBL Power Series Features The JBL Power Series consists of serious subwoofers that are unlike any others in their class. They will deliver unparalleled performance in a wide variety of enclosures, giving creative installers unprecedented flexibility in system design. The JBL Power Series incorporates: · Injection-molded Titanium composite cones for optimum combination of stiffness and low mass · Butyl rubber surround for lower harmonic distortion and precise voice-coil travel · Dual-stacked magnets and X-LinearTM motor assembly for controlled, long-throw cone excursion · DeepbeatTM anti-resonance chassis coating on the basket to prevent audible ringing · ThermosinkTM motor assembly coating to dissipate heat and increase power handling · Unique 5-ohm nominal impedance for extreme flexibility in installations with multiple subwoofers The JBL Power Series woofers are designed to maximize the sonic potential of any system. When installed in a proper enclosure they offer smooth frequency response, excellent transient response, high-output efficiency, and high-power handling capa-bility. The result is powerful, dynamic and accurate sound reproduction that could only come from JBL. A Few Words About Enclosures The enclosure or box that you choose for your Power Series woofer will define the sound that will ultimately come out of it. The size of the box and tuning frequency of port tubes in vented enclosures dictate the lowfrequency performance and output capability of your system. The flexibility designed into the Power Series subwoofers lets them make tons of bass in small sealed, vented and bandpass enclosures. They will also work well in infinite baffle applications where there is no space or budget to build a box. Be aware that infinite baffle or "free air" mounting will reduce the power handling and the low-frequency response of a subwoofer. Finally, although information is available for Bandpass enclosures from your JBL Dealer, any variations from the recommended dimensions should be made using dedicated enclosure-design software such as JBL SpeakershopTM. If this type of software is not available, assistance is available through JBL`s Web site at www.jbl.com or from your authorized JBL dealer. Your Car And The BASS Made In It Depending on the size of the vehicle, bass frequencies below 50Hz or 80Hz are actually boosted by nearly 12dB per octave as the frequency decreases. If you wanted to purchase that kind of power, you would need an amplifier that was eight times more powerful than the one you have. You can either reduce bass level to compensate for this, or simply sit back and enjoy the "free" bass. Enclosure Calculation and Building Recommended box designs are available from your JBL Dealer, or at www.jbl.com on the Internet. You may choose cabinet dimensions to fit your car, but the internal volume must not be changed, since changes in internal volume will change the tuning frequency of the enclosure. Please contact your authorized JBL dealer if you cannot do the necessary calculations yourself. The JBL SpeakershopTM dedicated enclosure-design software program may also be helpful for experienced car-audio enthusiasts. Sealed enclosures exert the most control over the motion of a subwoofer because the air acts like a spring against the motion of the woofer cone. Larger boxes allow for more excursion, thus more sound output for the amount of power used. When placed in a sealed box larger than the rated compliance (Vas) of the subwoofer, it will react as if it were in an infinite baffle installation. Vented and bandpass enclosures have the lowest amount of excursion for the amount of sound output. This is a result of port tuning reinforcing the sound output. Vented boxes will not provide adequate woofer control when driven below the port tuning range, meaning proper design is important. A fourth-order bandpass box will have the lowest 03 04 overall cone excursion at the expense of limited bandwidth. 1. Dimensions: Whenever possible, try not to make a box that has dimensions that are equal to, or multiples of, each other. For example, a 10" x 10" x 20" box would be susceptible to standing waves that may cancel some frequencies and add to cabinet resonance. A better alternative would be 18" x 11" x 10". 2. It is recommended that 3/4" (19mm) MDF be used to build the enclosure. Particle board is acceptable, but it is more difficult to work with. Enclosures for 12" and larger subwoofers, or small subwoofers, driven by high power amplifiers should be constructed out of 1" (25mm) material. 3. All joints should be glued and screwed; do not use nails. "Deck" or "Zip" screws are recommended since they have coarse threads for better grip and don`t require pre-drilling holes. Once the box has been tested, it should be sealed with caulk around all interior joints. 4. Apply a 1" thick sheet of polyfill (available at fabric and craft stores) to all inside walls except the wall where the subwoofer is mounted. If this is not done, increase the recommended box volume by 10 percent. 5. Use PVC or ABS pipe (cardboard tubing is acceptable if the walls are over 1/16" thick). Keep in mind the openings at either end of the port must be at least one port diameter away from any obstructions inside or outside of the box. Minimum recommended port size is as follows: 8" 10" 12" 15" Subwoofer Subwoofer Subwoofer Subwoofer ­ ­ ­ ­ 2" 3" 3" 4" Tools you will need: · Straight-edge · Saw (circular or table) · Screwdriver (powered or screwdriver bits in a variablespeed drill are best) · Sabre saw or keyhole saw (to cut hole for woofer) · Measuring tape · Soldering iron and solder · Wire cutters/strippers · Utility knife (to cut carpet) · Pencil Materials: · 3/4" or thicker MDF · Caulk · PVC or ABS pipe · Deck screws · Carpet · Carpet Adhesive (aerosol-type works well) · Speaker wire (12 or 16 gauge for woofers) Take your time and mark the wood carefully before making any cuts. The old adage "measure twice and cut once" definitely applies here. Use the straightedge to make sure your lines are straight, and clamp it to the wood to use it for guiding the saw if you are using a circular saw. This will get you the straightest edges, the best fit and the best sound. Possible Perils Pertaining To Power Handling The power-handling capability of any woofer is related to both its ability to dissipate heat, and the maximum excursion limits of its cone. Power handling for subwoofers is directly related to the type of enclosure that is chosen. The JBL Power Series subwoofers are designed to meet their power ratings in properly designed, sealed, vented, and bandpass boxes. Please be aware of the following: · Voice-coil overheating and burning is typically caused by overdriving an amplifier into "clipping" This damages more . speakers than any other cause. Damage occurs because the amplifier is too small rather than too large. Bass that sounds broken up and distorted at higher volumes usually indicates that the amplifier is being asked to deliver power beyond its capabilities. · Sharp "popping" sounds coming from a woofer indicate that the voice coil is "bottoming out" or hitting the back of the motor structure. This can seriously damage a woofer. Either your sealed box is too big or leaking air, the port tuning frequency of a vented box is too high or your amp may be overpowering the woofer. Fix the box, retune the box or turn the gain down on the amplifier respectively. · Infinite Baffle or "free air" mounting applications allow for greater cone excursion than subwoofers mounted in an enclosure. In order to compensate, the power rating of the subwoofer should be reduced to half its rated power. If the woofer "pops," turn down the amplifier gain. 5 Ohms And System Optimization In order to increase flexibility, the Power Series subwoofers are designed with a 5-ohm nominal impedance. This provides an extra margin of safety for simple installations, and allows those in competition or those who are always pushing the "edge" to use more woofers per amplifier channel safely and efficiently, without shutting the amplifier down or exceeding the amplifier`s SOA (Safe Operating Area), which could cause serious damage. In systems using multiple woofers per channel, please make sure your amplifier can drive lowimpedance loads safely and effectively. 05 Specifications Component Systems Specifications: P-800 35Hz ­ 5kHz 18W ­ 250W 200W 1.5" 90dB 5 ohms P-1000 30Hz ­ 1.5kHz 18W ­ 300W 260W 2.0" 90dB 5 ohms P-1200 25Hz ­ 2kHz 18W ­ 350W 280W 2.0" 92dB 5 ohms P-1500 20Hz ­ 1.2kHz 18W ­ 400W 300W 2.0" 93dB 5 ohms 06 Usable frequency range Recommended power amplifier range Continuous power handling Voice coil diameter Sensitivity (2.83 volt/1 meter) Impedance Thiele/Small Parameters Free-air resonance (Fs) Total Damping (Qt) Equivalent volume of compliance (Vas) One-way linear excursion (Xmax) One-way excursion limit (Xsvs) Cone area (Sd) Dimensions Overall frame diameter Cut-out diameter Mounting Depth Top mount Bottom mount 28Hz 0.34 2.37 cu. ft. 0.16" 0.6" 33.2 sq. in. 30Hz 0.38 3.01 cu. ft. 0.3" 1.12" 56 sq. in. 30Hz 0.45 5.21 cu. ft. 0.3" 1.21" 85 sq. in. 28Hz 0.43 10.42 cu. ft. 0.3" 0.91" 140 sq. in. 8.4" (213mm) 7.1" (180mm) 10.1" (257mm) 8.8" (224mm) 12.0" (305mm) 10.8" (274mm) 15.1" (384mm) 13.6" (345mm) 3.9" (99mm) 4.5" (114mm) 5.0" (127mm) 5.6" (142mm) 5.7" (145mm) 6.1" (155mm) 6.6" (168mm) 7.2" (183mm) Warranty Terms: 1-Year Transferable Limited Warranty This is an important document.
