An audio filter is positioned at the input of each audio integrated circuit (IC) chip to filter the audio signal intended for speakers. A low-pass filter is utilized for the woofer, while a high-pass filter is employed for midrange speakers and tweeters.

The audio filter design is critical in ensuring that each speaker type receives the appropriate frequency range for optimal performance. The low-pass filter allows frequencies below a certain cutoff frequency to pass through, effectively directing bass frequencies to the woofer. This enhances the low-end response and prevents higher frequencies from interfering with the woofer's performance.

Conversely, the high-pass filter is designed to allow frequencies above a specific cutoff frequency to pass, which is ideal for midrange speakers and tweeters. This filter blocks lower frequencies that could distort the sound quality and ensures that these speakers only reproduce the frequencies they are designed for, resulting in clearer and more accurate sound reproduction.

The integration of these filters at the input stage of audio IC chips is essential for achieving a well-balanced audio output across different speaker types. The design parameters, including the cutoff frequencies and filter order, must be carefully selected based on the specifications of the audio system and the characteristics of the speakers used. Properly designed filters contribute significantly to the overall sound quality and performance of the audio system.To the input of the every audio IC chip is placed an audio filter for filtering the audio signal for used speakers ( low pass for woofer, high pass for midranges and tweeters ) 🔗 External reference
