crossover Advantages and Features: 1. Audio-specific anti-interference high-power high-current high-voltage double 50uF large capacitor.Filter treble, midrange and low frequency above 290Hz2. The anti-interference 0.22uF capacitor filters the self-excitation and howling in the audio.3. The inductance length is close to 8cm, the inductance is 4.8mH, and the wire diameter is used 1.57mm high temperature enameled wire4. The design on is a gain of 12db, and it can withstand a power of about 1500W Rate.5. The upper limit frequency is about 260Hz~290Hz. Advantages and Features: 1.

Large inductance bass powerful dive 2. Use PCB fireproof board thick copper bottom plate circuit and increase the tin wire, so that the large The current flows smoothly 3. Solder- gold-plated terminals are more high-end and generous, easy to use, and do The workmanship is fine and the effect is awesome. 4. The anti-vibration foot pad is distributed, which is more convenient for installation.
