Description
 
The speaker system of the Tallboy type which adopted the double Woofer drive scheme.

A 20.3cm cone type unit is adopted as low-pass.
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.
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.

It is attached in two gilding input terminals corresponding to by amplifier, and the metals foot of the letter of a spike is attached.
