Introduce:  This is a high-low two-frequency divider designed for bookshelf boxes. The frequency division point is above 200Hz. Bookshelf boxes are generally placed in not very large places in the room to listen to, the distance is relatively close, and the commonly used volume is not very large. Use 3~8 inches of bass, suitable for listening to the low frequency at a distance of 0.5 meters to 2 meters, and the dull music is not good.  1: In addition to an inductor on the bass line, a capacitor is also connected in series. The capacity is around 110uf and the passage of the subwoofer (ultra low frequency) can be adjusted through the capacitor limit.  2: The treble part uses 2 capacitors in parallel and can be adjusted through the switch to adjust the volume. The penetration of high frequency will be better than that of a capacitor, and the sound quality will be relatively delicate.  3: A capacitor is added to the ground at the bass output position to make the bass frequency more smooth. This frequency divider is installed on the bookshelf box, which reflects the low frequency better. It is suitable for expressing vocals and strings because there is no interference from heavy bass. The frequency is particularly clean and nice, suitable for small rooms such as bedrooms, offices, and tea rooms.     Feature:  Power: 250W.  Crossover point: 2500Hz-3000Hz adjustable, There are 4 frequency points adjustable through two switches. (Recommended for woofers of 3-8 inch speakers).  Impedance: 4-8 ohms.  Size: 112*62*26(mm).  Net weight: 146g/pc.     Package includes:  1 x Crossover High and Low Two-way Divider
