The speaker system which supplied the technology and
experience which have so far been accumulated as a reference of the new
generation corresponding to high-quality medias, such as a DVD-Audio, and was
The AFAST (Acoustical Filter Assisted System Tuning)
technology is adopted as this speaker.
By adopting a vocal tube as the inside of an enclosure, or a horn opening,
this absorbs a stationary wave and vibration sound, suppresses an unnecessary
resonance, cancels an unstable order migration of the image by fluctuation
of a pitch (pitch of sound), and is improving the clearer reproductivity.
The 25cm cone type Woofer is carried in
What fully carried out tone-quality tuning by mixing a Kevlar in
cone paper equivalent to the TAD unit which is acknowledged as a speaker for a
studio monitor, and performing an aging treatment is adopted as a diaphragm.
The 3cm compression driver and the AFAST horn are carried in the high
The compression driver serves as an efficient design which supplied
the design know-how of TAD, adopts the diameter edgewise voice coil of 3cm of a
light weight and a high rigidity, and is aiming at the play of sound excellent
in the retroaction.
Moreover, the AFAST technology is introduced into the
horn, both an intensity and an internal loss are raised by mixing copper powder, and the vibration is suppressed by increasing weight.
In order to
reproduce the super-high region whose DVD-Audio is made possible, the ribbon
type super tweeter is developed newly and carried.
By adoption of the
magnetic circuit which uses a neodymium magnet, and an aluminum ribbon,
super-high region play capacity up to 120kHz which raised the efficiency ratio
is made possible.
It is being fixed from enclosure back and each unit
makes the extensive dynamic range possible with the high-resolution.
dividing network which adopted the high-quality sound part as the product-line
code, the choke coil, the capacitor, and the terminal, and attained thorough
low-loss-izing and low leakage-ization is adopted as a network part. Attention
was paid to especially the phase response especially of the inter-unit, and the
smoothness as a system is gained.
Moreover, the changeover termination also
corresponding to a bi-wiring interconnection, a by amplifier interconnection, and a multi-amplifier drive is carried.
3 position switching type level
control for tweeters is carried.
It is designed in pursuit of the ideal
of the speaker system "an enclosure sounds only a diaphragm without sounding."
First, an intensity is raised by adopting a trapezoid structure and the
unnecessary vibration is held down according to the three-layer structure which
sandwiched special damping materials further.
Furthermore, it is while arranging inside an enclosure the vocal tube by
the AFAST technology into which the technology of TAD which is a professional
studio monitor of Pioneer was developed further and reducing acoustic material
sharply,The occurrence of a stationary wave made into a Tallboy type weak
point is canceled (a patent is ending with application).
In addition, cross-sectional form made the trapezoid
enclosure the separate structure halved in the upper portion and the lower, and
technique, such as the speaker base made from special ceramics with a weight of
24kg and a round form, is given.
The natural bass play of a bass-reflex structure arranging a dimple on the base while establishing the path of sound in an omnidirectional from an enclosure lower etc. is aimed at.
