The unique trick used by Final Audio is that the roll-off frequencies for each driver section are determined by the relationship between the width of conductive coating between the driver sections and the assembly’s natural capacitance. Is that clever or what?!

The result is a multi-band speaker with separate sections for low bass, mid bass, midrange/treble, and uppermost treble. The added benefit is that the midrange- and treble sections can be made very narrow, resulting in a wide dispersion to cover a large listening area while providing excellent focus, independent of the precise listening position.

This also allows the creation of very narrow tweeter sections for improved high-frequency dispersion—traditionally a weakness of electrostatic speakers. The various printed sections also have different widths to help distribute and reduce resonances.
