All drivers are dipolar (planar or moving-coil). Bass drivers are no exception, and the only way to achieve (preserve) bass, is by preventing the out of phase back-wave cancelling the front wave.Low bass can be achieved using planar/electrostatic technology through several means. Firstly, you could enclose the bass driver, preventing the back-wave from interacting with the front-wave. Secondly, you could augment the bass with a conventional enclosed moving coil drive unit (hybrid designs like the Martin Logans). Moreover, big size helps. Big size prevents the back-wave working its way to the front (at least down to the upper bass), but at really low frequencies, you would need an infinite baffle (an enclosure) to prevent these destructive interactions.
