Divider bass uses inductance, high frequency porcelain resistance, metal capacitor. HIFI level sound effects. The midrange inductance is a rectangular hollow core inductor. High inductance inductors and high-quality metal film capacitors, self resetting fuse overcurrent protection. Add a tin wire on the back of the divider so that currents can pass through quickly and without loss. Good sound grade and excellent workmanship, long service life. Can effectively reduce the calorific value. Colour:White Material:plastic Package Contents: 1 * 3 way crossover Only the above package content, other products are not included.
