The active speaker kit is a training and practical electronic production kit, it looks beautiful, good quality. We choose the large magnet horn so the sound quality is good. The material of the shell is divided into lime wood and acrylic, the colors of acrylic boards are black and transparent. Each speaker is made of 6 pieces of 4 mm thick acrylic panels, and in order to make the whole structure more solid, we firmly fix three adjacent boards and each corner with a copper block. The transparent rubber soft pads at the bottom can not only resonate, but also protect the desktop from being scratched by the speaker.
The speaker uses original PAM8403 amplifier chip, which belongs to class D amplifier, with high power, high efficiency, low distortion and so on. Most of the audio signal capacitor is monolithic capacitor. The connection line between main and sub-speaker is used 5-core shielded cable to ensure the minimum distortion and smallest interference of the audio signal from the main speaker to the secondary speaker. The level indicating circuit of main speaker and sub-speaker is independent, even you adjust the volume potentiometer, it will not change the level of the level indicates status of two speakers.
