Hi-Fi -- Independent Bass --
The crossover will block the signal above the mid-low frequency. Only the real bass part is left. It feels that the human voice becomes very small.
Let the bass stand out. To compensate for the lack of low frequency sound.
Pure copper large inductor
High cost of using wire consumption Equal length of copper wire and iron core Skeleton winding
Double capacitor group A group of 12db/oct filter A group of reactance and resistance composition for the subwoofer Impedance compensation circuit RC wave circuit Absorb peaks, power amplifier promotes stability
PCB bottom plate Thick copper layer withstands high current
Add heat-resistant glue to components, double discs for solder joints, strong shock resistance in the subwoofer box, reliable and durable
