DC offset is a small amount of DC at the output terminals that is not desirable, but also not a big problem, and not typically enough to see visible cone movement. What you have is a BIG problem, much worse than just a bit of offset, it's quite a bit of DC.

DC-Offset. Audio signals are conveyed electrically as an 'alternating current' or 'AC' signal. This might typically result in a signal voltage that varies, for example, between +3 Volts and -3 Volts, with a waveform that is more or less symmetrical about the 0V line. However, there are circumstances — often, but not always, as the result of a ...

DC Offset, sometimes called “DC in the AC,” is usually the result of unbalanced loads or flaws in the power distribution system. This can cause DC current flow in the transformers that power your audio equipment, making them run hotter and produce an audible, mechanical hum.

Removal of DC offset is not a constant addition to the audio signal since DC offset tends to change over time due to changes in temperature or pressure. The DC offset should be removed with caution. A simple high pass filters is tricky to use because some of the zero Hz signal (which is the DC) might be actually part of the original signal.

DC offset is a potential source of clicks, distortion and loss of audio volume. This page explains the causes and dangers of offset and how to remove it. Ideally any DC offset that is present should be removed as the first editing step after recording audio or importing it, before any other editing is attempted.
