The speaker system which asked for the reality of
the original sound, inherited the design concept of TAD (Technical Audio
Devices) and Exclusive S5, and was developed by the concept in the high
sensitivity and the high efficiency.
Two 25cm cone type Woofers which
use an ALCC (alginic-acid composite cone) diaphragm are adopted as low-pass.
It is what mixed and carried out paper making of the alginate fiber, the alginate fiber extracted from seaweed, such as sea tangle, acts as a binder, and
this ALCC diaphragm is improving bonding strength, in order to heighten the
bonding strength of a high powerful poly ant rate fiber and pulp.
the magnetic-shield type double magnet magnetic circuit which added the
canceling magnet is adopted as a magnetic circuit, and the high flux density of
14,300 gauss is gained. Since T type pole is furthermore adopted and uniform
flux density is always obtained in order, the linearity of the swing to an input
Furthermore, in order to improve the responsibility at the
time of a small input and the Dainyuu power, the butterfly type damper which
looked over form again is adopted.
The horn type tweeter is adopted as a
The compression driver of the rear type with which high
resolution and the outstanding linearity are obtained is carried in honed
By the fading plug designed from research of hydrodynamics, the sound which
this compression driver is a thing of the same scheme as TAD and Exclusive
S5, and was emitted from the diaphragm is led to a core, turns into compressed
sound, and is emitted from a horn. Since it is the rear type which made
especially the pronunciation orientation of the diaphragm the orientation
of rear, the length of the path of the sound of a fading plug becomes respectively
the same, there is no disorder of the phase of the sound from each slit,
and the high region property is excellent.
In the diaphragm of this driver, 3cm titanium nitride is
adopted, it equips with the back cover excellent in the vibration proof made
from aluminum die-casting behind a diaphragm, and the occurrence of the
unnecessary oscillation is suppressed.
The large-sized oval wave horn is
adopted as a horn part. This horn is designing the form of the flare send out a
spherical wave, and, thereby, has realized a spread of a natural sound near the
simple sound source.
Furthermore, the reflection of sound is reduced by making a horn opening
round. Moreover, since horn form is an oval type, its horizontal directivity
is large and it can obtain a natural sound on a wide range listening point.
Molding accuracy has
adopted as the material of this horn aluminum die-casting which was highly
excellent in vibration suppression nature.
Moreover, AFAST (Acoustical
Filter Assisted System Tuning) of the new technology introduced by TAD is
introduced, and the resonator is formed in the horn upper portion. Thereby, the
transition of the phase could be smoothed and a more firm image orientation and
play sound have been obtained.
The network part selected only the
element of the low distortion carefully, it was made to distribute for every
unit further, and it arranges it, and, thereby, has prevented the time
interference of units.
Furthermore, the floating of the network board is
carried out from an enclosure, and it is intercepting the oscillation from each
In order to prevent an unnecessary oscillation of a baffle having
an ill effect on play sound, the tweeter Woofer is fixed with the original mid
ship mounting scheme of Pioneer.
The unnecessary oscillation of a baffle is
reduced by fixing a unit to the interior instead of a baffle.
enclosure is installing two single word I/O ports in a front in order to pull
out the bass-reflex effect which reinforces low-pass.
Compared with one
single word I/O port of the same dimension, there is little leakage of the
inside compass out of an enclosure, and it is reducing muddiness of the sound by
the interference from a unit.
Moreover, since the opening uses the R-shaped
special elastic body, there is little occurrence of wind end sound and an
elastic wave is emitted smoothly.
Furthermore, in order to improve a
low-pass property, it is considered as the mass enclosure of the internal volume
100L, and the diffraction phenomena of sound are prevented very much by making
the baffle of thickness into a round baffle.
Moreover, the high-density
particle board examined in sound is used for the quality of the material, and
finish is Chinese quince tone finish of the reddish dark brown colour.
The coordination which carried the attenuator in which high region level
adjustment is possible in the lower of the input terminal, and was united with
the status of the room by two positions of Normal/Decrease is possible.
