Bass second-order 12dB, treble second-order 12dB to achieve phase compensation, clean crossover professional speakers. High-power two-way frequency divider: The treble capacitor is a polypropylene audio coupling high-voltage anti-interference capacitor, the sound be more , and the treble switch makes it better adapt to the treble sound pressure. Use double protection: capacitor + resettable fuse. So that the treble is well protected during high-power work and not suddenly become silent due to high power. Solder- terminal block "Zero" technology does not require soldering wires, making it easier and faster. 1.2mm wire diameter, bass, high temperature resistance and large inductance, better show the flavor of sound quality.
