Adopt overcurrent protection device, durable and long service life. The PCB bottom plate adopts fireproof board, which is clear and clean. The four corners of are rounded, and the thick copper layer withstands high current. Capacitance is the key to the performance of the voltage divider. The tweeter adopts the famous non-inductive 100V1.5U two capacitors in parallel, overcurrent protection, etc., to super load capacity and long-lasting sound quality. In the speaker system, people call , the crossover circuit, and the speaker unit as the three parts of the speaker system, and the crossover circuit plays an extremely important role in whether the speaker system can high-value electro-acoustic signals. Beautiful appearance, fine workmanship. The use of polypropylene film frequency divider capacitors and high temperature line inductance coils super load capacity and long-term durable good sound quality. color:Photo color Material:plastic Package Contents: 2 x speaker crossover Only the above package content, other products are not included.
