Great choice of drivers!
In reviewing the patent plus a scientific paper on the technology (link below), I might call it an “Align Drive” or “LineDrive” acoustic engine because the twin section voice coil also aligns the voicecoil on axially throughout it’s travel, somewhat like a 4 link rear end keeps your axle at right angle to the drive line.
This scientific paper is phenominal in explaining the driver technology;
Clear Audio has also chosen the GranSun driver for their new headphone.
