Component Placement

Because of the JBL Component System’s small size and extremely versatile mount- ing options, there are an almost infinite number of placement options to achieve excellent sound quality in any vehicle. Please consider the following state- ments to help you get the most from your system.

1.The most spacious stereo image is achieved when the left and right speaker systems are placed as far apart as possible.

2.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.

3.Treble is directional in nature. 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.

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 out- put of a head unit or an amplifier (Figures 7 and 8).

A more advanced system design can be achieved by adding a Decade,™ 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 frequen- cies blocked by electrical means. Active or passive crossovers can be used in order to achieve the best system fidelity and widest dynamic range. Crossover fre- quency recommendations are given in the Specifications.
