Audio Database INFINITY Kappa Video 60,000yen(one-set, around the 1993 time) Description �@ The center loudspeaker with which the technology of the new Kappa series was supplied. The magnetic-shield design is performed in consideration of the destination in audio video. Two 13cm cone type Woofers by an IMG cone are carried in low-pass. This IMG cone is a cone which consisted of composite materials of a graphite fiber and polypropylene, and is fabricated under loud sound and a high voltage (injection molding: Injection Molding). The graphite fiber is radiately arranged toward the perimeter from the hub, and its undeformed operation area of a cone is large, and it has obtained the performance without a breaking up of a cone. Moreover, in order to raise special design-shaped a curvy linear cone (an intensity is added to the waveguide plunger under motion) and an intensity, the inverting dust cap by which the new-installation meter was carried out is adopted, and deformation of a cone is small suppressed also under the high power status. In the new Kappa serieses, a light weight and quantity rigidity-ization (it is light 10% and harder than before 5%) are attained from the conventional IMG cone, and a magnet and a cotton yarn line of phi133x19mm are used for a magnetic circuit. The planar drive type EMIT-R tweeter which adopted the circular diaphragm is carried in the high region. The planar diaphragm of an EMIT-R tweeter is using the ultra-thin KAPTON film, carries out photo etching of the annular voice coil to the top layer, constitutes a timbal, and is driving the diaphragm directly combining a special-shaped magnetic circuit. This has acquired the flat frequency characteristic and extensive directional characteristics. The enclosure has adopted the column-like polygon cabinet in order to suppress the influence of an internal stationary wave to a min. Moreover, it can attach with a ceiling or the surface of a wall. There was also a Black oak model as an ordering model.
