By applying such new techniques to planar loudspeaker construction,
Eminent Technology has been able to eliminate many of the flaws inherent
in earlier designs. The use of a welded channel-and-crossbar frame
dispenses with the need for perforated sheet metal (an “off-the-shelf”
material presumably used for reasons of economy and ease of
manufacture.) thus greatly improving dispersion, especially at high
frequencies.

Since it is now possible to have a powerful, precisely aligned magnet
structure on both sides of the diaphragm, true push-pull operation has been
achieved: Regardless of the degree of excursion the diaphragm undergoes,
the voice element is always optimally positioned within the magnetic field.
The result is extremely linear performance throughout the audible range,
with a profound increase in dynamic range and an absolute minimum of
distortion.
