StereoType

A modular wall-mounted DML audio system based on interchangeable resonant panels.

Professor: Stefano Maffei

Type: group

Year: 2026

Stereotype is not a traditional speaker, neither a decorative element.
It is a platform.

Stereotype is a modular wall-mounted audio system that allows users to customize their listening experience through interchangeable sound-radiating panels.

Instead of relying on a conventional speaker cone, the system uses distributed mode loudspeaker principles, where an exciter transfers vibration directly into a flat surface that becomes the source of sound.

The project is developed as an academic design proposal, but it is conceived and presented as a working prototype. Its ambition is to offer a clear product identity, strong spatial integration, and a unique form of physical sound customization through material choice.
