Description: HIFI ultrasonic directive(parametric) speaker kit(assembled)10mmx48pcs F/JDescriptionAbout This ItemsThis is a speaker that uses ultrasonic waves that allows you to enjoy extremely sharp directivity.The sound quality is about that of a pocket radio, but it's pretty good for a parametric speaker.I use 48 40kHz transducers.Because they use a special driver circuit, they have higher output than conventional parametric speakers.It can reach about 10m to 20m in a quiet room.We recommend a power supply of about 19V, which can be used for a long time. It can be used up to 24V, but the radiator gets hot.Please replace it with a larger type. It will be shipped fully assembled with simple adjustments.
