Adopt overcurrent protection device, 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 German non-inductive 100V1.5U two capacitors in parallel, overcurrent protection, etc., to its 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 restore high-value electro-acoustic signals. Beautiful appearance, fine workmanship. The use of polypropylene film frequency divider special capacitors and high temperature line inductance coils its super load capacity and long-term good sound quality. color:Photo color Material:plastic Package Contents: 4 x speaker crossover Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
