The small vertical twin speaker system which pursued
a feeling of a scale of the sound field which rival a floor type speaker in the
size made every shelf.
The vertical twin system which introduced the
wave-front control technology is adopted,Four points, "controlling a wave-front
diffraction by baffle form", are improved. [ "electric phases such as a network, are made "adjusting the energy time response of a Woofer and a tweeter on a time
base", "controlling the directivity of a Woofer and a tweeter", and to agree"
and ]
The oven cone which mixed and carried out paper making of the aramid fiber to pulp is adopted as low-pass, and low-pass resolution is raised
by raising a velocity of sound and obtaining a moderate internal loss.
Moreover, the AlNiCo-Magnet was adopted as the magnetic circuit and
low-distortion-ization is achieved by the synergistic effect with a copper short
ring and an OFC voice coil.
The 2.5cm dome shape tweeter which employed
the W.F. (wave front) director who took in the wave-front control technology is
adopted as a high region.
W.F. An energy time with a Woofer is controlled on
a time base by a director, and also horn form is performing the directive
control.
Newly developed new ceramic carbon is used for a diaphragm, and it
is a composite material of ceramic carbon and a ceramic graphite, and has
realized the higher velocity of sound and the Takauchi part loss.
The
AlNiCo-Magnet is adopted as a magnetic circuit.
Each unit has adopted
full mid ship mounting which suppresses an unnecessary oscillation of a baffle, and also has shielded the baffle and the unit with the shielding frame.
Thereby, thorough investigation of no vibrating and the absent-resonance-izing is carried out over the systemwide.
To a baffle,
it is as thick as 30mm, and the diffraction phenomena of sound are stopped by
adopting an elliptic curve round baffle.
Moreover, since electrostatic hair
transplantation to which a fine fiber is made to stick is given to the top layer
with static electricity and also hair is transplanted to the baffle mounting
hole, the unnecessary oscillation of a baffle and the unnecessary reflection are
suppressed.
The enclosure serves as Chinese quince tone finish of the calm
reddish dark brown colour.
The gilding terminal in which the bi-wiring
interconnection which separates the circuitry the object for low-pass and for
high regions, and can supply electric power is possible is adopted as a speaker
terminal.
Moreover, the gilding short bar is attached.
