So would the sound still be directional, or are we heading into omnidirectional territory? It's late, so I'm having trouble thinking it through, the spherical driver would push it in the omnidirectional territory, but I don't know what the stacked diaphragms would do, counter it, promote it, or what? Is that related at all to their staggered signal delay technology? (I suspect not.) They were actually stacking drivers, like a pseudo-line-source? So it's a pseudo-line-source with a slight omnidirectional bent, like the Gallo Reference 3.x, except with an electrostatic basis?
