Advantages and Features: 1. Audio-specific anti-interference high-power high-current high-voltage dual 50uF large capacitor. Filters treble, midrange and low frequency above 290Hz 2. The anti-interference 0.22uF capacitor reduces self-excitation and howling in the audio 3. Inductance length is close to 8cm, inductance is 4.8mH, using 1.57mm high temperature resistant enameled wire 4. Designed with a gain of 12dB, capable of handling approximately 1500W power 5. Upper limit frequency range is approximately 260Hz to 290Hz Features: 1. High current switch adjustable around 30Hz. Large inductance allows deep and powerful bass 2. Utilizes a PCB fireproof board with a thick copper base and increased tin plating for smooth high current flow 3. Solder-free gold-plated terminals provide a premium look, ease of use, fine craftsmanship, and excellent performance 4. Anti-vibration foot pads for easier installation Model: WEAH-89 Power: 1500W Applicable Impedance: 4~8Ω Upper Limit Frequency: 290Hz Dimensions: 117 x 95 x 56mm Material: PCB Color: As shown Package Contents: 1 x Bass Crossover Note: Light reflection and different displays may cause the color of the item in the picture to appear slightly different from the actual product. Measurement allows an error of +/- 1-3cm.
