High quality and durable components: a wire-wound ceramic resistor and high quality metal film capacitors deliver high load handling, long service life, and no burnout. Wide application: Hi-Fi sound filter module board, widely used in tweeters and woofer drivers, in car full-range speakers, or used on its own for highs or lows. Dual frequency crossover for highs and lows: a professional crossover commonly installed in loudspeakers. The mixed signal is split into treble and bass and routed to the respective high and bass driver units during playback, improving overall sound quality and playing a key role in splitting the full frequency signal. Clear Hi-Fi sound: the crossover enhances treble clarity and strengthens bass, enabling clear and natural music. It supports treble and bass frequencies, helps send the treble signal to the tweeter and divides the bass signal to the subwoofer unit. Use scenarios: - In a two-way hi-fi speaker system to improve frequency separation and overall clarity. - In car audio to balance treble detail with deeper bass for full-range speakers. - In DIY speaker projects as a standalone crossover to drive a tweeter or a subwoofer.
