A compact vertical twin speaker system with wave front control technology.

By adopting a vertical twin system with upper and lower woofer, sound field feeling and clear sound image localization are realized.
In addition, a wave front control technology has been introduced, and by strictly controlling four points : "adjusting the energy time response of the woofer and the tweeter on the time axis," "controlling directivity," "matching the electrical phase of the network, etc.," and "controlling the wave front diffraction by the baffle shape," a more realistic sound field and orientation is realized.

14 cm cone type woofer using newly developed oven cone of pulp containing aramid fiber is used for the low range.
This product is made from corn by mixing aramid fiber into pulp. This expands the range of piston motion of woofer and suppresses the generation of unnecessary natural vibration.
In addition, the frame of the unit is made of aluminum die-cast, and the shape is designed to use the acoustic resistance of the rear surface of the cone.

A 2 cm dome type tweeter with a W. F. (wave front) director is adopted for the high range.
In order to match the energy time response with the woofer, the W. F. director controls the position of the vibration plate of the tweeter and controls the directivity by making the horn shape smooth.
In addition, the rigidity of the tweeter has been greatly improved by inserting a honeycomb-shaped rib in the flange of the tweeter, which suppresses the squeal of the flange and realizes a reproduction sound with less dirt.
Ceramic carbon with carbon purity of 99.9% is used for the diaphragm.

The baffle has a large round shape to reduce the diffraction phenomenon of the low pitch.
Six sides of the enclosure, including the back side, are Red-Dark Brown color with Hananashi finish.
In addition, since the duct part on the back side is floating, turbidity due to plate vibration of the back plate and cross modulation radiated from the duct is reduced.

There was a speaker base (CP-11) that was sold separately and matched with the body design and adopted a special molded plywood.
