4 way speaker system which operated the highest unit in the best piston motion
zone, and was developed by the basis of the concept of investigating the high
musicality and art of a quality.
The 31cm corn type Woofer is carried in
In order to aim at correspondence to digital sauce, the carbon
graphite corn is adopted as a diaphragm, and also rigidity is improved by making
into two-layer structure in piles the corn in which angles differed on the
two-sheet same axle. Moreover, a circle-like hollow is established in the
portion of the root of a corn, high frequency is cut, the resonance of a chamber
is suppressed, and intensity is raised.
A balanced type magnetism circuit is
adopted as a magnetic circuit, and the movement toward the upper and lower sides
is kept equal. a voice coil is an edgewise volume of an oxygen-free-copper line
-- furthermore, long -- since a voice coil, high imitation nature has been
obtained also in the Dainyuu power.
A thing 160mm in diameter is adopted as
a magnet, distortion by back electromotive force is controlled by attaching a
copper cap to a pole, and the rise of impedance is suppressed.
hard dome shape squawker is carried in inside low-pass.
The newly developed
material is adopted as a diaphragm and high efficiency of 97dB is realized by a
balanced type magnetism circuit and adopting a copper cap like a Woofer.
It is light to a voice coil and the edgewise volume of the high copper
Klatt aluminum wire of a conductometric is adopted as it, and though it
is a squawker, wide-range-ization (150Hz - 10kHz) is realized as the simple
The equalizer is using polycarbonate, it has structure which
does not resonate easily, and 52S material which can be used also for a
diaphragm is supplied to the frame.
Furthermore, the low-pass characteristic is improved by preparing a back
The 6cm hard dome shape
high-speed-steel coker is carried in the mid-high range.
Relation of sound
is improved by adopting the same diaphragm as a squawker, and also supposing
that it is structurally the same.
The high-definition play in a piston
motion zone is enabled by using only 4kHz - 8kHz with a unit simple substance, although a play (500Hz - 20kHz) is possible.
The 2.2cm hard dome shape
tweeter is carried in the high region.
The same material as a squawker and a
high-speed-steel coker is used for the diaphragm, and flattening is attained to
the play limit of a unit by forming lightweight high rigidity.
A play (5kHz
- 40kHz) is possible for this unit, and the crossover is set as 8kHz or more.
The distributed architecture which made the wiring board of a Woofer and
crown compass become independent completely is used for a network part.
silicon steel plate core excellent in the characteristic in a low-pitched sound
region is adopted as the coil of a Woofer, a 1.4mm oxygen-free-copper line is
coiled, and improvement in the engine performance is aimed at. Moreover, the
good fair light core of the high region characteristic is adopted as the coil of
a mid-high range, and the oxygen-free-copper line is twisted.
special electrolytic condenser of new development [ object / for Woofers ], a
capacitor is a black gate capacitor to a low-pass cut for squawkers,WT capacitor
is adopted as a high-speed-steel coker, MF capacitor is adopted as a tweeter, and adoption in which the characteristic of each capacitor was employed
efficiently is performed.
Moreover, low distorted-ization is attained with
sticking-by-pressure wiring, and the 0.18mmphi56 core oxygen-free-copper line is
used for internal wiring material.
Highest-class high-density particle
board is used for the baffle before and after the enclosure, re-plywood of the
two 15mm thickness is carried out, and intensity is raised. Moreover,
diffraction phenomena are reduced because front and back gives a round baffle.
The thing of 25mm thickness is used for pleuron, and also the time of the 20mm thick board has been carried out to the side, the top plate, and the sole plate as reinforcement, respectively, and the thickness of pleuron has become 45mm. Furthermore, two reinforcements are fixed to a front baffle at the transverse direction. Moreover, rigidity is improved to the rear baffle by using a front baffle mechanism omission board for reinforcement, and also passing a gusset plate all around.
