A solid front stage with a good image is one of the most difficult tasks to achieve in a vehicle. No car has the
optimum listening environment.This makes proper sound staging very difficult to accomplish. Most speakers
tend to be placed where they will fit easily, as opposed to where they can perform the best.The mounting
location of your speakers will have a great effect on the sound quality of your stereo system.The special care
taken to place the speakers will yield many hours of listening enjoyment in return. Several important recom-
mendations should be followed.
• Place the speakers where they have a direct path to the listening area.
• For the best integration between 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 problems) which will affect the speaker's ability to reproduce
the frequency range around the crossover frequency of the system.
• Whenever possible, place the tweeter directly above or below the
midrange as this maximizes the imaging (point source) capability of the
speakers (Figure 1).
• Sound radiated from a "point source" provides the best stereo imaging
because the separation of the acoustical centers between the midrange
and tweeter for each channel is at the optimum distance. In a closed en-
vironment such as an automobile, horizontal speaker alignment (Figure
2) can cause amplitude 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. Mounting the speaker with
minimum path length difference will ensure the best
staging and imaging possible from your audio system.
