Composite assembly for a motor vehicle

A composite assembly for a motor vehicle, the composite assembly comprising:

• at least one electroacoustic transducer for emitting sound waves;
• at least one wall element of the motor vehicle, behind which the transducer is mounted in a concealed manner;
• an intermediate element for influencing the sound emission behavior is arranged between the transducer and the wall element, the intermediate element having a contact surface facing the wall element for transmitting the sound waves;
• and
• a recess in which there is no contact between the intermediate element and the wall element is formed within the contact surface,
• wherein the contact surface has a plurality of recesses.
