Introduce:The treble circuit is a treble circuit with capacitors in series and inductors connected to the ground, and the switch can be adjusted to make the loudspeaker clear and bright. However, it can be compatible with midrange speakers between 3 inches and 6.5 inches. The bass line is a large in..

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 ..

Description:      The frequency divider is suitable for a high-pitched mid-range two-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 qua..
