Advantages and Features: 1. Audio-specific anti-interference high-power high-current high-voltage double 50uF 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 resistant 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.Features: 1. The high current switch can be adjusted around 30Hz. inductance bass powerfuldive 2. Use PCB fireproof board thick copper bottom plate circuit and increase the tin wire, so that the The current flows smoothly3. 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.Model: -89Power: 1500WApplicable impedance: 4~8Upper limit frequency: 290Hzsize: 117 x 95 x 56mmMaterial: pcbcolour: As shownPackage Contents: 1 x bass crossoverOnly 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.
