Ujjdwiurgh HiFi 150W Bookshelf Speaker Dedicated Crossover 1 High 1 Low 2 Way Adjustable Audiophiles for Superior Sound Controls

2. The crossover is composed of an inductor coil and a capacitor. The inductor alleviate the direct current of the power amplifier to the speaker and filter out the interference of ultra-high frequency. 1.This BT-218 crossover is to solve the problem of head-booming. It solves the problem of head-booming by connecting a large capacitor in series after the inductor. 3. The inductive reactance enhance the strength, and cooperate with 2 capacitors to filter out the signal below 70Hz of the power amplifier speaker beyond the limit range, so that the is purer, the strength is enhanced and the resonance head-booming problem is solved. 4. There are 2 capacitors on the treble line, and the capacity can be controlled by the switch, so that the sound details are richer and the frequency requirements suitable for oneself are achieved. 5. It is recommended to choose some better fever songs during installation, listen to more songs, and debug the effect through the switch inside. Only by trying more can you get the best effect.
