3. 500GTi are engineered to provide excellent frequency response low distortion and high power handling in a minimum size The small size of the GTi Woofer Midranges is made possible through the use of a Neodymium magnet assembly with JBL s Stray Field Containment Geometry By preventing stray magnetic fields this closed circuit magnetic assembly design concentrates the magnetic field on the voice coil where it provides superior performance This high concentration of magnetic power is coupled to a 2 Edge wound Aluminum 4 Wire High Temperature Fiberglass Voice Coil This voice coil uses lightweight aluminum wire to maintain the agility to reproduce high frequencies while ts large diameter assures extremely high thermal power handling The cone motion of these high excursion designs is controlled by a Aromatic Polyamid Fiber Spider This new material is able to control the 0 6 motion of the cone while maintaining musical accuracy because it is 3 times stronger than conventional spider materials Treated Kevlar fiber cones are used because of their combination of low weight high stiffness and resistance to resonances The 400 and 500GTi Woofer Midranges are topped off with a treated fabric inverted dome for smooth reproduction of high frequencies What does all this technology add up to A driver with flat frequency response excellent off axis response and high output capability all in a small and elegant package The resul

6. eeds Component Placement The location of each of the loudspeakers plays a vital role in achieving proper frequency response and spacious imaging Because the 400 and 500GTi have an extremely wide and smooth dispersion pattern excellent performance may be achieved in any vehicle Because of the wide variety of vehicles there is not one right way to locate the 400 and 500GTi however knowledge of the following considerations will help you get the most from your system 1 The most spacious stereo image is achieved when the 400 and 500GTi s are placed as wide apart as possible The best center image will be achieved when the distance from the left speaker to your left ear is as equal as possible to the distance from the right speaker to your right ear This is most easily achieved by placing the 400 and 500GTi as far forward as you can The best system integration is achieved when the woofer midrange is mounted close to the tweeter Installing the tweeter close to the woofer midrange helps smooth the transition from woofer midrange to tweeter at the crossover point You will get the best frequency response when the path from the woofer midrange and tweeter to your ear is unobstructed Because of the high acoustic energy capability of the 400 and 500GTIi they must be securely mounted in a rigid panel which is free from resonances rattles and air leakage Installation Warnings and Tips Be careful not to cut or d

9. imum of 12dB per octave slope be used for the transition point between the subwoofer and the 400 or 500GTi The optimum crossover frequency for this transition is de pendent on the specific components used the vehicle and other installation details As a general rule the crossover frequency should be as low as possible to achieve the best sys tem imaging You can fine tune the crossover after the installation is complete for the best sound A good place to start your tuning process is between 50Hz and 150Hz when using the 500GTi and between 80Hz and 150Hz when using the 400G7i In 4 way sys tems using a midbass driver such as the 600GTi the crossover point may be raised higher without detrimentally affecting imaging as long as the midbass drivers can be mounted reasonably close to the midranges This higher crossover fre quency will allow the system to play louder Since no crossover is perfect it is advisable to keep your crossover points away from the range where your hearing is most sensitive Therefore we recommend that you try to keep the high pass frequency below 250Hz and the low pass above 2500Hz This lets the 400 or 500GTi reproduce the entire range of frequencies covering the most important vocal and lead instrument fundamentals without a crossover point If you prefer to use all passive crossovers you will need to construct or purchase either a low pass or band pass filter for the midrange driver and match it to a h
