Sony MDR-Z1000 - Manual (Page 3)

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 3 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.
