Special reminder:

This board is a subwoofer pre-amplifier, directly connected to the speaker, it will not produce sound. It must be connected to a pure post-amplifier board to make an active subwoofer to produce sound. The power of the pure post-amplifier board is shocking according to personal needs. The degree of selection, the greater the power of the pure power amplifier, the more shocking the bass effect. The so-called low-pass filter board filters out the high-pitched part above the human voice, and retains the low-frequency part to amplify to increase the bass reproduction strength. Human voice and high-frequency instrument sound will not be heard during playback. Buyers must understand this knowledge to avoid not knowing how to use it after buying it.
