The speaker system developed from a new
high-sensitivity technology at the base in the wave-front control technology
cultivated by development of a vertical twin system, and the high speed-ized
Two Woofers which used 14cmALCC (alginic-acid composite
cone) for the diaphragm are carried in low-pass.
In order that this
diaphragm may heighten the bonding strength of a high-rigidity substance and
pulp, it is 混抄(ing) the alginate fiber which extracted from seaweed, such as sea
tangle, and fibrosed, and is improving bonding strength sharply because this
alginate fiber works as a binder.
The dome shape tweeter of 2.0cm is
adopted as the high region.
The pure ceramic carbon of 99.9% of a purity and
the new ceramic carbon borne by the composite material of the ceramic graphite
of 99.99% of a carbon purity are adopted as a diaphragm.
Furthermore, the new model-like cross shaped W.F. (wave front) director
is employed as the front, and a wave front, an image lateralization, a
feeling of sound field, etc. are controlled on the listening point with
the wave-front control technology.
Especially the new model-like horn is excellent in perpendicular and
horizontal intention nature, and supports a sideways and both of every length.
Moreover, the packing which has the vibration suppression effect around a
director is added so that a director may not generate an unnecessary
The magnetic circuit of each unit serves as a
magnetic-shield type with a canceling magnet.
In order [ which
incidental sound sticks because an oscillation of a unit gets across to a
baffle, and makes play sound muddy ] for a thing to protect, full mid ship
mounting is adopted. The Woofer and the tweeter are firmly fixed to the interior
of an enclosure, and an oscillation of a unit is not told to a baffle, but the
unnecessary oscillation is suppressed.
In order that an enclosure may
heighten the bass-reflex effect, it has adopted the double duct and has improved
the image lateralization with centralization of a voice-source location, and a
symmetrical location. Moreover, the duct opening has performed the round
treatment and is reducing the wind end sound and the diffraction of a duct.
Finish is considering all the 6th page including a rear view as Chinese
quince tone finish of the reddish dark brown colour, and is reducing the
diffraction of sound by the round baffle.
