Audio Module (AUD) (2006): Design: Loudspeakers

All versions of the audio module (AUD) permit the installation of two pairs of loudspeakers:

• front loudspeakers in the front doors
• rear speakers in the rear doors. For C70, the rear speakers are in the side panels.

In some versions of the audio module (AUD), a treble speaker can be connected to the front and rear speakers. Premium Sound also contains a loudspeaker mounted centrally in the dashboard. Treble loudspeakers, when installed, are always installed in the upper parts of the doors. The three audio module (AUD) versions have different loudspeaker arrangements:

Performance 

• one pair of front loudspeakers
• one pair of rear loudspeakers.

The loudspeakers are the broad range type and cover the whole frequency range. In England and USA there is also a smaller type of treble loudspeaker in the front doors.

High Performance 

• one pair of front bass speakers with treble loudspeakers
• a rear pair of loudspeakers with treble speakers.

The front treble speakers are electrically connected to the same signal cable as the front loudspeakers. The rear treble speakers are electrically connected to the rear loudspeakers.

Premium Sound 

• a front pair of 3-way loudspeakers consisting of a pair of 2-way loudspeakers (bass and mid range) with treble speakers
• a rear pair of loudspeakers with treble speakers
• a 2-way centrally mounted loudspeaker (available in two versions ¹⁾ ) positioned in the dashboard.

The front treble speakers are electrically connected to the same signal cable as the front loudspeakers. The rear treble speakers are electrically connected to the rear loudspeakers.

¹⁾ When the display is installed in the dashboard the bass and mid range elements of the center loudspeaker are 3¹ /₂ inch, otherwise 5 inch.
