They are difficult to disassemble, to repair and to upgrade. The concept Open System Speaker aims to minimize obsolescence through decentralized production and a modular design. Construction, production and sale of the Bluetooth speaker are designed in an open system. Electronic components from various manufacturers can be exchanged, integrated and updated. All parts are accessible and customizable via an online platform.
