It uses very high-end and easy-to-use wiring terminals. Press the black/white button to insert the wire and release it to clamp the bare wire on the wiring terminal. Press again to pull out the wire. It can also be welded on a copper plate with reasonable design. The inductance is made of oxygen-free copper enameled wire, and dual inductances dedicated for audio are connected in series and staggered by 90 degrees. Since the frequency divider is composed of multiple inductors, the inductors will induce each other, and the coupling effect like a transformer will cause intermodulation interference, which will seriously affect the sound quality. Stagger the two inductors by 90 degrees to cut off the coupling path. Change the frequency to apply more speakers. The old crossovers are rigid. If they are not suitable for users, they cannot be changed after they are installed. Sometimes the treble is too harsh and the bass performance is poor, which is difficult for beginners to solve; even if the crossover is replaced, it may not be appropriate. And the cost is higher. The frequency divider has added frequency adjustment function, which can adapt to a variety of speakers.
