The 3 way speaker system which carries the horn
tweeter of 90 degree revolving type.
A 30cm cone type unit is adopted as
low-pass.
It is a unit which bears the Dainyuu power by FB cone and an
aluminum voice coil adopting it as vibration system, and adopting a large-sized
ferrite magnet and a long voice coil as a time circuitry.
Moreover, fo in a
speaker simple substance is as low as 19Hz, and the enclosure which packed
sufficient acoustic material has realized the low-pass play.
The 12cm unit which uses FB cone which used the model deep to a mid range
and secured the intensity is adopted. In this unit, directional characteristics
are also raised by the effect of a cone central dome.
Moreover, the cap was attached to the
inside side of a cabinet, and the influence of the back pressure from a Woofer
is prevented.
The multicellar horn unit of 90 degree revolving type is
adopted as the high region.
The unit in which the multicellar horn of the
diaphragm of 25mmphi and the product made from aluminum die-casting which
fabricated the hard duralumin of 30micro thickness in the shape of a dome was
put together has realized the play to a 28000Hz high region.
This unit has the unique structure where the orientation of a horn can
be rotated 90 degrees. The directional characteristics which do not change
by this also when a speaker is installed in which of length and width are
acquired. Moreover, the scheme which suppressed distortion by interference
is adopted as the installment to a baffle board.
The object for
mid ranges and the level control for high regions are carried in the front.
