Using the EAW AX396 is easy. First, place it in a suitable location where you want to project sound. Make sure it's on a stable surface. Connect it to your audio source using the appropriate cables. When it comes to volume, start at a low level and gradually increase it to avoid any sudden loud noises. As for maintenance, keep it clean by gently wiping the exterior with a soft cloth. Avoid exposing it to extreme temperatures or moisture. Also, check the cables regularly for any signs of damage. If you notice any issues, contact a professional for repair.
