It is the floor type speaker system which adopted the dabbled live system.
It is a unique design [ say / making reproducing
characteristics equalize ] by carrying out the parallel drive of the aperture of
30cm, and the 20cm corn type unit low-pass, and raising radiant efficiency, and
also changing an aperture.
The heavy low-pitched sound play is enabled by
adjusting tuning of two Woofers.
The corn type unit (30cm and 20cm) is adopted as low-pass. The characteristic
improvement is aimed at by the thing which will raise radiant efficiency
by carrying out the parallel drive of these units, and also will carry
out two kinds of sizes and to do.
Two of these have been
arranged perpendicularly and a spread in stereophonic reproduction is improved.
The 3cm corn type unit which uses an aluminum alloy molding board is
adopted as a super-high region.
The level control of the step type which
can change a level to a three-stage in 2000Hz - 25000Hz is carried in the front.
