The frequency division point is above 200hzthis frequency divider is installed on the bookshelf box, which reflects the low frequency betterfeature:brand: weahmodel: 204power: 250wcrossover point: 2500hz-3000hz adjustable, there are 4 frequency points adjustable through two switchesuse 3~8 inches of bass, suitable for listening to the low frequency at a distance of 0the frequency is particularly clean and nice, suitable for small rooms such as bedrooms, offices, and tea rooms3: a capacitor is added to the ground at the bass output position to make the bass frequency more smooththe penetration of high frequency will be better than that of a capacitor, and the sound quality will be relatively delicatethe capacity is around 110uf and the passage of the subwoofer (ultra low frequency) can be adjusted through the capacitor limit(recommended for woofers of 3-8 inch speakers)imped5 meters to 2 meters, and the dull music is not goodbookshelf 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 large1: in addition to an inductor on the bass line, a capacitor is also connected in seriesit is suitable for expressing vocals and strings because there is no interference from heavy bassintroduce:this is a high-low two-frequency divider designed for bookshelf boxes2: the treble part uses 2 capacitors in parallel and can be adjusted through the switch to adjust the volume
