•Place the speakers where they have a direct path to the listening area.

• When using the Punch Splits, there are two options for speaker place-

ment between the midrange and tweeter. For the best integration be- tween the midrange and tweeter,

the tweeter should be placed less than 2" from the midrange. (Figure 1)

• If you cannot place the tweeter less than 2" from the midrange, then place the tweeter more than 7" from the midrange. Placing the tweeter 2"-7" from the midrange can cause destructive interference (frequency response prob- lems) which will affect the speaker’s ability to reproduce the frequency range around the crossover frequency of the Punch Splits system.

•Whenever possible, place the tweeter directly above or below the midrange as this maximizes the imaging (point source) capability of the Punch Splits speakers. (Figure 2)

Soundradiatedfroma“pointsource”hasthemostoptimumstereo imaging because the separation of the acoustical centers between the midrange and tweeter for each channel is at the optimum. Figure 2-Adescribes a horizontal speaker alignment. In a closed environment such as an automobile, horizontal speaker alignment can cause severe ampli- tude and phase differences which will degrade not only the imaging, but also the frequency response. This is due to the path length differences between the midrange and tweeter. Figure 2-Bdisplays a vertical alignment between the midrange and tweeter. With a vertical alignment, the path length differences between the midrange and tweeter are reduced to a minimum. The result is a negligible difference in path lengths between the midrange and tweeter regard- less of the proximity of the listener to the speakers. Mounting the
