The frequency divider is suitable for a high-pitched mid-range bass speaker, or a single-bass low-middle speaker. The speaker is suitable for 4-8 ohms impedance. The design is based on the 4-8 ohms mass value design. Most products are the same, in order to improve the sound quality. Product parameters: Model: (high, medium and low three-way three-way divider). Size: 94 mm long, 73 mm wide, 32 mm thick. Cutoff points: 1000Hz and 5000HZ Maxmium Power: 150W. Circuit: The treble is standard 12db/oct and the bass is standard 12db/oct. Ingredients: The inductor is made of enamelled copper wire. The high-frequency capacitor uses high-voltage metallization special capacitor, with minimum error of +/- 3% and high withstand voltage of 400V. It effectively prevents the low-frequency voltage from passing over and the tweeter. The bass capacitor is used normally. Electrolytic capacitor, withstand voltage of 100V. The design is reasonable, the appearance is exquisite, and the sound quality is also excellent. colour: as shown Material: ABS 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.
