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 recommendations 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 environment 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.
