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. The tweeter
level can be adjusted on the pc board of the x-over, to compensate for different mounting
locations.
■
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. To temporary
mount the tweeter, double sided tape can be used.
■
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
to your car.
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 on the installation side.
2 Dash Board
Sometimes aggressive sound and overly brilliant treble reproduction caused by the horn
loading effects of the front window.
3 Window Triangle
Bright sound combined with a high soundstage, sometimes sounding a bit “nervous”
with some side biasing.
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 an additional person sitting on the
passenger seat.
Note: A “on-axis” installation (with tweeters directly pointing at the listener) is not required,
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 floa-
ting on top of the dashboard.
The tweeters come with swiveling function, play around with it – but don’t overdo the job!
