Speaker Circuit. Speakers contain a long wound loop of wire called a voice coil. The output signal has both ac and dc component and dc component is undesirable and can t be fed to speaker.
The output signal has both ac and dc component and dc component is undesirable and can t be fed to speaker. A basic equivalent circuit of the speaker can be made by only using two components. The amplifier sends an audio signal out through the speaker output into the first.
There are several ways to wire up speakers the most common methods are series and parallel.
Although the cost involved compared to its passive counterpart is much higher an active system has definitely a clear edge over the passive systems.

When i was tinkering with the circuit i found that removing the 470uf capacitor connected to non working speaker and shorting the wire the speaker starts receiving sound.
