2-2 Ultra wideband HD driver unit

This device uses a “HD (High

Definition) driver units” that is very

unique and can play sounds from a low

frequency to ultra high frequency with

only one unit. The diaphragm comprises

of the Liquid Crystal Polymer mentioned

earlier. The shape of the diaphragm

underwent hundreds of shape pattern

simulations and numerous listening

tests before it was finalized. Also, 360

kJ/m

high power neodymium magnets

are used, providing the source of

power needed to drive the diaphragm,

enabling reproduction of a wide range of

frequencies from 5 Hz to 80 kHz.

2-3 High-grade 7N-OFC Litz cord

The cord for transmitting the signal uses grade 7N OFC (Oxygen

Free Copper) of extremely high purity (99.99999 %). Suppressing

signal loss in the cord minimizes sound degradation.
