Warning: this is a really dangerous and stupid idea. On the other hand it would provide almost infinite frequency response especially at the low end of the spectrum.
A strong magnetic field is imposed with the north pole and south pole opposing each other. Across the air gap metal plates provide
a high (variable) voltage. The air is made conductive by a source of ionizing radiation. The current perpendicular to the magnetic field produces a force on the air that can be modulated to produce any frequency of sound. Since there is no speaker cone, travel is not limited.
