Using the Daichi Dome Horn Tweeter Speaker is easy. First, make sure to connect it to a compatible amplifier according to the impedance specifications (it's 8Ω). You can use it in long - throw PA setups or in large rooms to get great sound. When handling the speaker, be gentle as it has a delicate HiFi Dome driver. Avoid exposing it to extreme temperatures or humidity. For maintenance, keep it clean by using a soft, dry cloth to wipe the exterior. Check the connections regularly to ensure they are secure. If you notice any issues like reduced sound quality or strange noises, it's best to consult a professional.
