To use these WorxAudio V8i loudspeakers, first connect them to your audio source like a mixer or amplifier using appropriate cables. Place them in a position where sound can spread evenly, like on stands for a wider coverage. When handling, be careful not to drop or bump them as it might damage the internal components. Keep them away from moisture and extreme temperatures. For maintenance, clean the exterior regularly with a soft, dry cloth. Check the connections periodically to make sure they are secure. This will help keep your loudspeakers working great for a long time.
