1. components: The speaker crossover features a high-frequency circuit with capacitors in series and inductors to ground, as well as an adjustable switch that allows you to control the size of the sound and clear and bright high-frequency sound. 2.10 microfarad mid-range filter: The speakers filter frequency divider uses a 10-microfarad mid-range filter to filter out low-frequency and high-frequency sounds, making it compatible with mid-range speakers between 3 and 6.5 inches in size, while the large inductance in the low-frequency circuit limits high-frequency sounds from passing through. 3. Two-stage low-frequency circuit: To prevent interference between high and mid-range frequencies, the HiFi audio speaker crossover also features a two-stage low-frequency circuit with a capacitor to ground that provides powerful and impactful bass. 4. Easy-to-use terminal connections: The audio HiFi filter circuit board has switches for each frequency range, and its terminals are designed for easy connection without soldering, making it a convenient and user-friendly solution for upgrading your audio system. 5. Adjustable frequency points: The audio speaker frequency divider module features an adjustable switch that allows you to fine-tune the frequency points between 5200Hz-5500Hz, providing greater flexibility and adaptability to different types of speakers. With its high-temperature resistance and large inductance, the crossover delivers excellent sound quality and prevents music resonance.
