Commentary
This 2-way speaker system uses Infiniti's original EMIT tweeter.
A 25 cm cone type woofer is installed in the low range.
Polypropylene is used for the cone part, and the Q of general paper cone is as low as 7 ~ 9 compared to 80 ~ 100, and it reduces waving phenomenon and deflection of the cone and prevents muddy sound.
The high-range is equipped with EMIT (Electromagnetic Induction Tweeter), a full-drive type tweeter originally developed by Infiniti.
Samarium-cobalt, the most powerful magnetic material, is a full-surface drive type sandwiched by ultra-thin and ultra-lightweight plastic diaphragms, achieving excellent high-frequency reproduction.
