A speaker reproduces the AC voltage of a guitar signal by travelling forwards and backwards (I.e. Alternating between positive swing and negative swing). This creates compression waves in the air and hence, sound.
DC is a constant positive swing. The speaker would be in a instant state of positive excursion. If it can't go back to rest...then no compression wave was generated hence, no sound.
