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.
