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
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.
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.
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
