Features: 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 , suitable for listening to the low frequency at a distance of 0.5 meters to 2 meters, and the dull music is not good. In addition to an inductor on the 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. 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. A capacitor-to-ground is added to the output position to make the frequency appear smoother. This crossover is installed on the bookshelf box, which reflects better low frequency. It is suitable for expressing vocals and strings. Because there is no interference from heavy , you I will feel that his mid-to-high frequency is particularly clean and nice, and it is suitable for small rooms such as bedrooms, offices, and tea rooms.
