[. . . ] Similarly, the woofer cones are manufactured with a proprietary injection-molded titanium-composite cone in order to deliver the clarity and effortless power that have made JBL famous. This cone is suspended by a heavy butyl-rubber surround, which serves to absorb any remaining cone resonances for the clearest, most articulate reproduction of voices and other mid-range sounds. As a bonus, the butyl-rubber surround is impervious to temperature extremes and humidity, making it ideal for automotive applications. [. . . ] The best center image will be achieved when the distance from the left speaker and the right speakers are as equal as possible from your listening position. This is most easily achieved by placing the speakers as far forward as possible. This means that high frequencies are reduced as you move off the tweeter's axis. The angle mounts will allow the tweeters to be pointed across the car to the listener on the opposite side. This will make each listener slightly off-axis to the tweeter that is closest to that listener, which helps to compensate for the fact that the listener is always closer to one tweeter than to the other (see Figure 6). The best system integration is achieved when the tweeter is mounted close to the midwoofer speaker. This helps smooth the transition from the midrange and tweeter at the crossover point. Choosing mounting locations that satisfy all of the above criteria will provide the most satisfying performance. Left Figure 6 Right System Design There are a variety of system options available with the Component System. The simplest configuration is to use them full range with their built-in passive crossovers by connecting them to the output of a head unit or an amplifier (Figures 7 and 8). A more advanced system design can be achieved by adding a Decade, TM GT, Power, GTi, or equivalent subwoofer to your component system. In this case the component system will be used as high and midbass frequency drivers and should have their extremely low frequencies blocked by electrical means. Active or passive crossovers can be used in order to achieve the best system fidelity and widest dynamic range. Crossover frequency recommendations are given in the Specifications.

However, the use of a small amplifier to attain very high volume levels could lead to over-driving the amplifier. [. . . ] When listening at high volume levels, always use hearing protection or turn the volume down! 06 Specifications Component Systems Model P-62c Power Series Automotive 6-1/2" 2-Way Component System 1/2" titanium-composite neodymium magnet tweeter.
