Purpose and fitment for Mercedes W166

This component has been developed specifically for the Mercedes W166 body and for installation in the front left door. The design of the triangle corresponds to the geometry of the door frame and the exterior mirror base, allowing for secure mounting without the need for modifications. The mounting holes and edge shapes are adapted to the factory door panel, ensuring proper sealing and fitment against the upholstery after installation.

Function in the Bang&Olufsen audio system

The triangle serves as a support and cover for the Bang&Olufsen tweeter, ensuring it remains stable in an optimal acoustic position. Correct placement of the tweeter in this door zone promotes a precise soundstage and better high-frequency dispersion within the cabin. The properly shaped surface of the triangle helps to reduce unwanted mechanical resonances, which translates into cleaner audio playback.

Design characteristics

The speaker triangle is manufactured as a component matched to the lines of the pillar and mirror housing, maintaining consistency with other door components. The applied mounting geometry allows for secure anchoring within the door structure, minimizing the risk of looseness during operation. The shape of the outer surface is selected to blend harmoniously with the upholstery and mirror housing, creating a uniform, visually organized area.

Condition, service, and tuning applications

The offered triangle falls under the Exterior Mirrors category, which highlights its close connection to the mirror mounting area and the finish of this part of the door. As a used component, it provides a practical solution for replacing a damaged triangle after a collision, mirror removal, or audio system modifications. It can also be used in projects where the vehicle owner is retrofitting the interior with Bang&Olufsen components while maintaining the factory look of the doors.
