Theoretical Circuit

The theoretical circuit is available in form 1.Passive materials with mediocre dimension is used by the manufacturer. In order to make a theoretical circuit one needs a printed circuit diagram. In a circuit diagram it is observed that the circuit has one entry with two exits. In the entry portion the exit portion of the amplifier is connected and in the exit the crossover is connected. Two crossovers one with high frequency and the other with low frequency is used. The path from the entry to the crossover is none other than a filter with a very high frequency. Similarly the way to the crossover with low frequency is a filter with low passage. The filter of low passage consists of an inductor L2 and a capacitor C2.The inductor is in the same line with the circuit and the capacitor with the crossover.

The complex resistance changes in association with the price of the frequency. The price of the complex resistor of inductor is directly proportional to the frequency and that of the capacitor is inversely proportional to its frequency. With the increase in frequency the self induction acquires bigger complex resistance and the capacitor a smaller one. Thus this combination provides no provision for the higher frequencies to go close to the crossovers. The provision in the same way is reversed when higher frequency filter passes a crossover with a high frequency. Capacitor C1 is placed at the same time and place. In this arrangement as the frequency increases the complex resistance of the capacitor decreases but in the case of the inductor at the same time when working with the crossover the frequency increases. As long as the frequency is increased the capacitor facilitates the passage of frequency and least fully it absorbs the induction force from the same.

Apart from the filter elements present in the circuit the existence resistors and the capacitors stabilize the functioning of the crossovers.R3 an additional resistance in the circuit performs a different function and operation. This so called R3 resistance offers shorts a safety point in the design. By chance if a high voltage current passes through it creates a danger of burning the crossover with a high frequency which can burn up the crossover and the present resistance and the sound level is also decreased.
