So, this looks like basically a flexible electrostatic speaker? Which means almost no bass and highly directional?

  Not quite, since an electrostatic speaker requires the surrounding layers to be electrically charged to move the diaphragm. This appears to be closer in form to a piezo (or array of piezos) where the diaphragm itself moves under the electric charge.

  Not exactly. This isn't a dipole, it's expanding and contracting across its whole surface. So, almost no bass (no excursion) and not as directional as if it were a dipole. Electrostatics put out the inverse wave behind them, this is either mounted on a rigid object (no back radiation) or in free air (in-phase back radiation, and front radiation is half as powerful as it would be against an object)
