The speaker system of the Tallboy type which adopted
the double Woofer drive scheme.
A 20.3cm cone type unit is adopted as
Polypropylene and a high rigidity graphite fiber are combined with
a diaphragm material, and the IMG (Injection Molded Graphite) cone which raised
a moderate internal loss and intensity is adopted.
A 12.7cm IMG cone
type unit is adopted as the mid range.
The 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.
Furthermore, the dust cap which strengthens
rigidity is adopted as the cone center which a physical stress concentrates.
The EMIT-R type unit which improved the EMIT type tweeter by a
technology original with Infiniti is adopted as the high region.
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.
It is attached in two gilding input
terminals corresponding to by amplifier, and the metals foot of the letter of a
spike is attached.
