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
n
tests with the tweeter mounted to different locations inside the vehicle. For this, double
sided tape can be used.
Set all tone controls, i.e. pre-EQ, treble / bass and loudness functions of your headunit
n
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 to get right, i.e. high mounting efforts.
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 -6 dB may help.
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 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!
