Your subwoofer has a durable premium finish. To clean, use a damp soft cloth. Do not use a strong or abrasive cleaner. Avoid getting any part of the subwoofer system wet. Do not place wet objects (drinking glasses, potted plants, etc.) directly on top of your new subwoofer. A coaster must be used every time. If allowed to soak in, even a small amount of water may permanently damage the gorgeous high-end furniture finish.
