Using this EAW Otto Adaptive Subwoofer is easy. First, make sure to connect it to a proper audio source, but remember it doesn't come with a power supply, so you'll need to provide your own.

You can gently wipe the surface with a soft cloth. Don't expose it to extreme temperatures or moisture to ensure its long - term functionality. Enjoy the powerful bass it provides!
