The small vertical twin speaker system which
introduced the wave-front control technology.
By adopting the vertical twin system which installed the Woofer up and down, a feeling of sound field and a clear image lateralization are realized.
furthermore -- having introduced the wave-front control technology --
"adjusting the energy time response of a Woofer and a tweeter on a time base",
"controlling a directivity", "agreeing electric phases, such as a network,", and
"baffle form,More real sound field and lateralization are realized by
controlling four points of control" for a wave-front diffraction strictly.
The 14cm cone type Woofer using the oven cone of the newly developed
pulp containing an aramid fiber is adopted as low-pass.
The material which mixed the aramid fiber in pulp is being used for this
diaphragm. By this, the waveguide-plunger motion band of a Woofer is expanded
and the unnecessary natural oscillation is reduced.
Moreover, the frame of the unit is made into form which
is a product made from aluminum die-casting, and is that the sound resistor on
the back of a cone is adopted.
The 2cm dome shape tweeter which employed
the W.F. (wave front) director is adopted as a high region.
W.F. By the
director, in order to coincide an energy time response with a Woofer, the
diaphragm location of a tweeter is controlled and the directive control is
performed by considering it as still more smooth horn form.
rigidity is sharply improved by putting a honeycomb-shaped rib into the flange
of a tweeter. Thereby, the resonance of the flange was suppressed and little
play sound of dirt is realized.
The ceramic carbon of 99.9% of a carbon
purity is adopted as a diaphragm.
The baffle serves as form around [
form ] it went greatly in order to reduce the diffraction phenomena of a bass.
The enclosure serves as Chinese quince tone finish of the reddish dark
brown colour in the 6th page also including a rear view.
Moreover, since the floating of the duct fraction on the back is carried
out, it is reducing the muddiness by the cross modulation emitted from
the panel vibration and the duct of a back board.
The main-unit design was matched as the option and
there was the speaker base (CP-11) which adopted special formed plywood.
