However, traditional audio crossovers often have problems such as poor sound quality and unsatisfactory crossover effects, which are mainly attributed to the unreasonable selection of crossover components and circuit design.

[0004] Researchers and engineers have been exploring and improving the design of audio crossovers. They try to use different types of components such as resistors, capacitors, and inductors, as well as optimize circuit design to improve the performance and sound quality of the crossover. In this process, some new materials and technologies are gradually applied to the production of audio crossovers, such as professional constant resistance potentiometers, oxygen-free copper wire hollow inductors, metal film capacitors, etc. The application of these new materials and technologies makes it possible to improve the performance of audio crossovers.

[0005] There are still some deficiencies in the existing audio crossovers. Some crossovers do not perform well in the high or low frequency bands, resulting in distorted sound or high distortion. In addition, the circuit design of some crossovers is complex, resulting in high manufacturing costs and difficult maintenance. Therefore, it is necessary to continue to study and improve the design of audio crossovers to improve their performance, sound quality and reliability.

[0006] Therefore, there is an urgent need for a frequency divider that uses professional components and optimized circuit design, adopts a multi-resistor parallel treble attenuation circuit and a multi-capacitor parallel treble frequency division circuit to effectively improve the sound quality and performance of the audio system.
