Maintenance
To ensure the longevity and optimal performance of your Teufel STEREO M 2 speakers, follow these maintenance guidelines:
- Cleaning: Use a soft, dry, lint-free cloth to clean the speaker surfaces. For stubborn marks, slightly dampen the cloth with water. Avoid abrasive cleaners, solvents, or chemical sprays, as these can damage the finish.

- Wood Cabinet: The speaker cabinet is constructed from FSC®-certified wood. Treat it with care to prevent scratches or dents. Avoid placing the speakers in direct sunlight or near heat sources.
- Dust: Regularly dust the speakers, especially around the drivers and vents, to prevent dust buildup which can affect sound quality and internal components.
