The size of an audio transformer depends on the following parameters : Frequency range. Current drive/power. With lower frequency, to maintain the same impedance, the self/mutual inductance of the transformer has to be increased. Since self-inductance is directly proportional to size, size has to be increased to support low frequency.

The blocking capacitor in series with the primary winding of the transformer provides the negative bias, reset voltage, for the magnetizing inductance. Without the blocking capacitor, there could be a duty-ratio-dependent DC voltage (DC offset) across the winding and the transformer could go into saturation. This approach works well where the frequency is high
