It will not sound when directly connected to the speaker. It must be connected to a pure final stage power amplifier board to make an active subwoofer. The power of the pure final stage power amplifier board is shocked according to individual needs. The degree of selection, the higher the power of the pure final stage power amplifier, the more shocking the bass effect. The so-called low-pass filter board filters out the high-pitched parts above the human voice, and retains the low-frequency part to zoom in to improve the bass playback strength, and does not hear human voices and high-frequency instrument sounds during playback. Buyers must understand this knowledge to avoid using it and not knowing how to use it.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan style='font-size:18px;font-family:\"Times New Roman\"'\u003eMost of the subwoofers in the market are basically dual-powered.
