FEATURES
Rare-earth Samarium-cobalt magnet
magnetic circuit
Rare earth samarium-cobalt magnets with
high magnetic energy are built into the limited
volume of the super tweeter. Its powerful magnetic
characteristics, combined with the electromagnetic
soft iron showing extra low carbon and low impurity
used for the pole yoke and plate, constitute an
ultra-strong magnetic circuit with a magnetic flux
-4
density of 2 Tesla and a total flux of 40x10 Wb.
