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 developed.

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 low-pass.
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 region.
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.

The 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.
