The speaker system made by the theory of completely new a design and a measurement on the theme of reproducing " carrying out and carrying out "eliminating distortion of a time-domain completely" of the "time correctly.

Two units which adopted the powerful magnet, the small caliber diaphragm, and the large-diameter voice coil are carried in the Woofer. Furthermore, by applying a horn loading to all the bands, the low-pass latency which happens by transition of the phase response near fo is improved.

In order to remove the unnecessary signal component-multipath ghost distortion and reverb distortion accompanied by a time-lag, the curve which three, the cross section of a horn, form, and an impedance, interlock, and changes smoothly is developed, and the new vibration suppression method which absorbs an enclosure oscillation is performed.
