Purpose and Function in the Audio System

The woofer speaker grille plays a key role in the correct mounting of the transducer in the front of the vehicle. This component:

• stabilizes the speaker's position in the door,
• limits vibrations of the door structure in the immediate vicinity of the transducer,
• helps direct the acoustic wave towards the cabin,
• protects the speaker basket from accidental mechanical damage from the inside of the door.

Thanks to its proper fit to the BMW G series structure, the grille supports the maintenance of the factory sound character, especially in the low-frequency range.
