The compact floor type 3 way speaker system which
aimed at reproducing more correctly from a basic bass region to the upper
register besides an audio frequency band.
122A of the 30cm aperture
developed for exclusive use is adopted as low-pass.
In order to realize the cone paper which prepared the rib with the optimal
mass or a stiffness, and the exact piston action stabilized also in the
time of a large swing, it has the technical special features, such as attaching
a mass media trawl ring to a voice coil.
LE5-5 of the diameter of 13cm is adopted as a mid range.
combining a ring-like diaphragm and a powerful magnetic circuit with a
high region -- high -- the ring radiator 077 which realized the efficiency upper
register play is adopted.
From the horn of unique form with the property of both exponential / diffraction,
it is spread with large directional characteristics (110 degrees x 40 degrees)
It is the graceful design which allotted the top of the enclosure smoked
