Correct. I missread the original post.
This is just a guess: If there is some series resistor (for current
limiting) in line with the speaker, this resistor and the capacitor
should construct some sort of low pass filter. I.e.: The speaker is
driven with a square wave voltage that has many harmonics. The low pass
filter can cut off may of the harmonics making a better "sound". The
speaker, as beeing an inert mechanical system, has a low pass filter
"build in".

The capacitor
simply eliminates the DC offset on the signal.
Not the way he described it being
connected, across the speaker.
