Product Description The crossover is to distinguish the sound signals of different frequency bands, amplify them separately, and then send them to the speakers of the corresponding frequency bands for playback. When reproducing high-quality sound, electronic frequency division processing is required. The crossover is the "brain" in the speaker and is crucial to the quality of the sound. The music signal output by the power amplifier must be processed by the filter element in the crossover to allow the signal of the specific frequency of each unit to pass. To scientifically, reasonably and rigorously design the crossover of the speaker, we can effectively modify the different characteristics of the speaker unit, optimize the combination, make each unit play to its strengths and avoid its weaknesses, and give full play to its potential, so that the frequency response of each frequency band becomes smooth and the sound and image phase is accurate, so that the music played by the high, medium and low frequencies can have distinct levels, be in sync, bright, comfortable, wide and natural sound quality effects.
