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 the 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 . In the speaker system, people call , the crossover circuit, and the speaker unit as the 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 inductance coils super load capacity and long-term durable good sound . color:Photo color Material:plastic Contents: 2 x speaker crossover Only the above content, other are not included. Note: Light reflection and different displays may the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
