A frequency divider is a nonlinear device that produces an oscillation frequency that is a divisor of its input frequency. It refers to distinguishing the sound signals of different frequency bands, respectively giving them to the amplification, and then sending them to the speakers of the corresponding frequency bands for playback. In high quality sound reproduction, electronic crossover processing is required.
The crossover is the "brain" in the speaker, which is very important for the sound quality. The music signal output by the power amplifier must be processed by the filter wave component in the frequency divider to allow the signals of specific frequencies of each unit to pass. It is necessary to scientifically design, rationally and rigorously design the frequency divider of the speaker to effectively modify the different characteristics of the speaker unit, optimize the combination, so that each unit can develop its strengths and avoid weaknesses, and exert its potential as much as possible to make the frequency response of each frequency band change. Smooth, accurate phase of the sound image, in order to make the music played by high, medium and low sounds clear, co-ordinated, clear, comfortable, wide and natural sound quality.
The following is a circuit diagram of the divider.

Copper Cooling Tube
[HIGH REFRIGERATION EFFICIENCY]Good heat dissipation and refrigeration capability,high strength at low temperature.Copper tubes are hollow,so has strong heat transfer capability.If you need refrigeration for refrigerators, freezers, air conditioners, this is a good choice
[COPPER MATERIAL]Copper refrigerator tube has the features of high temperature resistance, corrosion resistance, oxidation resistance, durability, long service life[SOFT & SHAPE CHANGEABLE]Because refrigeration copper pipe can bend and deform, they can often be made into elbows and joints. Smooth bending allows copper tubes to bend at any angle
[WIDELY APPLICATION]Refrigerator Tubing is not only used for refrigerator, freezer and air conditioner as refrigeration tubing coil, but also used as a HVAC system pipe.
