COAXIAL PLACEMENT CONSIDERATIONS In most cases, speakers in the coaxial

configuration will be placed into factory speaker locations. If you have some speaker mounting flexibility, keep the following in mind: Lower mounting locations, such as the lower front corner (See Diagram F) of a door or a kick-panel provide the greatest path length distances for the sound emitted by the speakers. For this reason, they are generally more desirable than higher mounting locations. Higher mounting locations will usually result in extreme near-side soundstage bias which compromises the stereo listening experience (See Diagram E).

COMPONENT PLACEMENT CONSIDERATIONS A component system configuration gives you the

ability to place the woofer and tweeter separately in your vehicle interior. This can be good or bad, depending on how it’s done. As a general rule, the tweeters should be placed relatively close to the woofers for best tonal balance and most coherent imaging (the closer, the better). Any separation greater than 8 inches (20 cm) is likely to result in degraded sound quality (See Diagram H).

Avoid placing tweeters where they will be blocked
