The speaker system which reexamined the mounting
scheme of the unit from the origin, and planned the thorough high rigidity and
the absent resonance.
It fixes to a rigid, making a Woofer and a tweeter become independent of
a front baffle in oscillation, and the technique of intercepting the oscillating
channels of communication of each inter-unit further is taken. This is
reducing the oscillation of the front baffle constituting the cause of
the blot of the image or less of a common cabinet to 1/10.
The 35cm cone type Woofer which used the pure cross carbon
diaphragm is carried in low-pass.
By knitting up a finer fiber with high
density as compared with common pure cross carbon, the cone lightweight as it is
is realized for rigidity.
Moreover, the vibration dissolution structure is
adopted as a diaphragm for the first time as a Woofer unit, and the flat sound
pressure property and the outstanding transient are gained.
large-sized magnet of phi220xphi110x25tmm and a phi100mm large-diameter voice
coil are carried, and the diaphragm is driven with high fidelity.
newly developed diamond joint coat diaphragm by an original process and the 8cm
dome shape squawker with which the vibration dissolution technology was united
are carried in the mid range.
The diaphragm of this unit developed further the plasma night rye dead
way which ceramics-izes the base material of titanium itself and high-rigidity-izes
it, and has obtained the hardness which is a diamond joint coat diaphragm
in which the super-hard diamond was formed on the diaphragm top layer,
and was excellent.
Furthermore, by adoption of the vibration
dissolution structure diaphragm by a laser beam machining, distortion by a
time-domain is suppressed thoroughly.
The 2.5cm dome shape tweeter which
adopted the diamond joint coat diaphragm like the mid range is carried in the
Furthermore, the diaphragm structure which cancels the peek of
a high region vibration is adopted, and the high-speed responsibility and the
transient are raised.
The quality part chosen by the repetition of the audition is used for a network part, and also in order to eliminate the slight
influence which an oscillation of a part has, the zircon sand filling network
TAP box is introduced.
Even if it made it approach, the component partses of
most networks without the problem of a cross interferencee were stored in the
dedicated-network TAP box, and this is filled up with the increased specific
gravity zircon sand. The fine oscillation of a network part was removed by this, and distortion by unnecessary vibration of network parts is eliminated.
Moreover, about a choke coil, a three-dimensional placement is carried out
on the outside of a network TAP box, and the mutual interference is made into
Furthermore, in order to maintain a network purity, neither the
printed circuit board nor a pewter was used, but each element product line is
direct connected with the crimp type terminal.
