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. For this, 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 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!
