The speaker system which aimed at the reproductivity
of the sound field which introduced the wave-front control technology into the
vertical twin newly, and were more excellent in it, and the clearer image
In order to employ the merit of a vertical twin speaker
efficiently further, the wave front of sound reached the listener's ear how, or
the actual condition was solved scientifically, and a new wave-front control
technology is introduced.
the point -- "baffle form "which electric phases,
such as a network, are made to agree [ "controls the directivity of a Woofer and
a tweeter" ]", [ "which adjusts the energy time response of a Woofer and a
tweeter on a time base" ]By four points of controlling a wave-front
diffraction", the wave of sound enables the propagation of the wave front of a
beautiful sound which spreads uniformly by these-controlling.
Two 20cm cone type Woofers using the newly developed cone that mixed the
aramid fiber in pulp are adopted as low-pass.
Moreover, a short ring is used for the Alnico magnetic circuit of a new-installation
meter, and it attains a Low-noise-izing further, and is raising driving
force further by edgewise voice coil adoption.
A frame is aluminum die-casting of a high rigidity, and is
intercepting the unnecessary oscillation by adopting a shielding frame gasket as
The 3cm dome shape tweeter which employed the W.F. (wave front)
director is adopted as a high region.
The diaphragm location of the tweeter
was controlled so that the peek of a riser was in agreement, and also the
directivity is controlled with a director's horn form, by this, the wave front
of the sound in a listener's listening location is made to coalesce, and the
reproductivity of sound field and the image lateralization are raised more.
A director has few resonances fabricated by the special elastic body, and is
firmly fixed to an aluminum die-casting flange.
The ceramic graphite of
99.99% of a carbon purity is adopted, and in a magnetic circuit, flux density is
large, and has adopted the quality AlNiCo-Magnet as a diaphragm in it.
Each unit has adopted full mid ship mounting, a Woofer is fixed to the
inner baffle prepared in the interior of an enclosure, and the tweeter is firmly
fixed from a rear view through a spacer.
The unnecessary oscillation of the
baffle was suppressed by this and little natural play sound of the distorted
feeling has been obtained.
Distribution of the unit was used for the
network and it has prevented the cross interferencee of each unit.
round treatment was carried out greatly and the top baffle has controlled the
Moreover, it is designed so that it may be flattened
with a lower baffle at the time of a saran net attachment, and it is tuned up so
that the tone quality which is in the status of an attachment and was excellent
may be obtained.
Finish of the enclosure is Chinese quince tone finish of
the reddish dark brown colour.
The large-sized terminal in which a
bi-wiring interconnection is possible is adopted.
