Frequency Divider - The function of the frequency divider is to separate the mixed analog audio signals into high, medium and low parts, and then send them to the corresponding high, medium and low woofer units to play. thus achieving the purpose of improving sound quality. | Professional - This is a three-way KTV for tweeter + mediant + bass, a professional stage speaker crossover and a DIY upgrade tool designed to improve audio quality. High quality capacitors - low loss and high quality, eliminating the problem of electrolytic capacitors. | High quality materials - high temperature resistant wire, wire wound ceramic resistor and imported metal film. Overcurrent protection design, simple and beautiful lines, reasonable component layout. Small switch can adjust the treble (usually 3 dB can be added). | Ensure large power handling, long life and very good sound quality. If you have any questions, please contact us, we will do our best to serve you. | 2PCS Speaker Frequency Divider Crossover 3-Way 300W HiFi Audio Speaker Heights Mid Bass 3-Units Crossover Filter for 3-5 Inch Speakers
