  • A third amplifier is used to drive one speaker terminal to the same DC potential as the speaker's other terminal. This achieves a 0V DC potential across the speaker.
    A coupling capacitor is not needed since there is no net DC voltage across the speaker and, hence, no DC current through the speaker.
