Using these loudspeakers is easy. First, find a stable place to set them up. Make sure to connect them to the correct power supply that comes with the set. Once powered on, you can connect them to your audio source like a music player or a mixer. When it comes to maintenance, keep them clean by using a soft, dry cloth. Avoid exposing them to extreme temperatures or humidity. And always handle them gently to prevent any damage. If you notice any issues, check the power connection first before seeking further help.
