quality components and adjustable frequency control: The speaker crossover uses a frequency circuit with capacitors in series and inductors to ground, plus an adjustable switch to shape the sound, delivering a clear and bright frequency response. Midrange filter and compatibility: The divider uses a 10 microfarad midrange filter to filter out unwanted low and frequencies, making it compatible with midrange speakers between 3 and 6.5 inches in size. The large inductance in the lowfrequency circuit helps limit frequency leakage. Twostage lowfrequency circuit for better separation and bass impact: To prevent interference between and midrange frequencies, the HiFi audio speaker crossover includes a twostage lowfrequency path with a capacitor to ground that provides powerful and impactful bass. Easytouse terminal connections for quick upgrades: The circuit board has switches for each frequency range, and its terminals are designed for easy connection without soldering, offering a convenient and userfriendly solution for upgrading your audio system. Use scenarios and applications: Upgrading a bookshelf speaker system with 3 to 6.5 inch drivers to achieve clearer highs, better tonal balance, and an improved soundstage. Replacing a factory crossover in a HiFi speaker to gain more precise frequency control and reduced driver interaction. DIY speaker projects where solder terminals simplify assembly and rapid prototyping while preserving audio performance.
