Using overcurrent protection device, durable, and has a long service life. The high-volume part adopts the famous noninductive capacity in parallel, and the high power non- capacitor, the low frequency part is converted by inductance to achieve a clear and full effect. PCB floor with fire board, thick copper layer can withstand current. Use of polypropylene film divider capacitance and high temperature resistance wire inductance coil, guarantees carrying power and long-term durability and very good sound .
