Increasing flux density and achieving highly sensitive playback:
0kJ/m³ high power neodymium magnets
To enhance sound resolution, 440 kJ/m³ high power neodymium magnets which boast the highest
energy efficiency among general industrial goods were used. They supply clear mid and high tones and
powerful bass.
A manufacturing method called the “transverse field pressing method” boosts the magnetic force of
neodymium magnets even higher. This is a manufacturing method designed to strengthen magnetic
force even further by arranging the orientation of magnetic powder particles parallel in directionality
from the N pole to the S pole of the magnetic field that magnetizes the particles.
