The crossover uses a professional crossover processing chip to effectively protect the sound output performance to be stable and powerful. Adopt MKP film capacitor, with high withstand voltage, small lead loss, small internal temperature rise, negative capacitance temperature coefficient, and excellent flame retardant performance. The metal aluminum shell resistor has a heat sink slot, high power, and good overload bearing capacity. Built-in tweeter protection bulb can continuously protect the tweeter from being burned out.
