TWEETER MOUNTING LOCATION
The tweeter positioning does exhibit a direct and profound influence on the front staging
of your component system. Depending on the chosen location where the tweeters will
be installed, different loudness levels in the high-frequency region will result.
n
To determine the best tweeter location, it may be necessary to carry out short listening
tests with the tweeter mounted to different locations inside the vehicle. For this, double
sided tape adhesive can be used.
n
Set all tone controls, i.e. pre-EQ, treble/bass and loudness functions of your headunit
to the neutral position first, before you attempt any listening test of the speakers installed
in your car.
Attention:
The influence of the tweeter mounting location on the front staging remains –
and care must be taken to achieve a good compromise between unobtrusive mounting
and good sound quality.
Examples of different tweeter mounting locations, and the results that are most frequently
obtained, are explained below:
1 A-Pillar
Best option concerning the depth of image and overall sound balance of the
component system. Not that easy to get right, i.e. serious mounting efforts involved.
2 Dash Board
Sometimes aggressive sound and overly brilliant treble reproduction caused by the
horn loading effects of the front window. Setting tweeter ATT switch to -3 dB may help
to get rid of it.
3 Window Triangle
Bright sound combined with a high soundstage, sometimes sounding a bit “nervous”
with some side biasing too.
4 On the upper end of the door panel
Balanced sound with good staging qualities
5 Right on top of the mid/woofer
Good staging, but often “dull” sound, especially with a person sitting on the
passenger's seat.
Note:
A “on-axis” installation (with tweeters directly pointing at the listener) is not re-
quired, neither recommended. Tweeters directly aiming at the listener’s ears are usually
responsible for the unwanted “side-biasing” effect, where the sound seems to originate
from the drivers, instead of floating on top of the dashboard.
