The floor type speaker system which kept the basics faithfully on the basis
of the ideal "the speaker which forgets an entity of an audio equipment
and can be fascinated by the music itself", and maintained the whole
balance for the completeness of each unit with slight height on it.
EL-403 which is a 40cm cone type Woofer is adopted as
Newly developed cone paper is used for the diaphragm, and low-pass
distortion is reduced by the highly efficient low-distortion magnetic circuit by
ED-915 of a driver unit and horn EH-351S are adopted
as a mid-high range.
ED-915 has realized a 22kHz high region play with the
large diameter of 48mm in diameter using the ultralight diaphragm made from a
beryllium. Moreover, the Mie slit type was adopted as the fading plug, and the
super-precision instrument manipulation and the interval have improved the
transient. The AlNiCo-Magnet is adopted as a magnet.

is constituted by wooden [ made of plywood / the 2nd phon of ].
which is a horn type super tweeter is adopted as a super-high region.
combination of a high flux density magnetic circuit with a beryllium diaphragm
35mm in diameter and a rare earth magnet has realized a 45kHz high region play.
Moreover, the horn part serves as a diffraction type with a large
EN-907 is adopted as a network part.
The design which
is equal also to a maximum of 300W input is performed, and a tone-quality
modification, such as using the metallized film type focused on a tone quality
for a Low-noise-izing, the reduction in direct current resistance, and a
capacitor, is aimed at in the coil.
Moreover, the panel side is equipped
with the termination for multi-amplifier which is easy to use.
