The speaker system of the Tallboy type which adopted
the double Woofer drive scheme.
A 20.3cm cone type unit is adopted as
The IMG (Injection Molded Graphite) cone which was combining
polypropylene and a high rigidity graphite fiber with the diaphragm material, and raised a moderate internal loss and intensity is adopted.
type unit which adopted a 12.7cm IMG cone is adopted as the mid range.
IMG cone adopted as the mid range chose the mixed ratio of polypropylene and a
graphite fiber, and has attained high rigidity by the low-mass.
the dust cap which strengthens rigidity is adopted as the cone center which a
physical stress concentrates.
The EMIT-R type unit which is an advanced
type of the EMIT type tweeter developed by the technology original with Infiniti
is adopted as the high region.
A planar diaphragm 3cm in diameter is
adopted, and the Tran Gent property, low distortion, and wide-range play which
are the special features that an EMIT type tweeter is big are realized.
Two gilding input terminals (low-pass, high region) are carried, and the
metals foot of the letter of a spike is attached.
