Commentary

A speaker system capable of handling the wide dynamic range of the latest recording technology.

A 21 cm cone type woofer using Reinforced Plastiflexed cone is installed in the low range.

A 1.9 cm dome type tweeter using a polymer diaphragm is mounted in the high range.
This unit uses magnetic fluid to increase cooling effect.

The unit layout is opposite to that of a typical speaker system, with a tweeter placed below.
It was conceived by Henry Azima during the development of the 700 and was designed with the intention of equalizing the distance from the sound center of the drive unit to the listener's ear.

The front baffle board is injection-molded from polypropylene and natural minerals.
The natural mineral composition is unique to the mission, and the baffle provides a controlled and accurate response to low-frequency transients and optimal stiffness to minimize mid-range resonance.

There was a speaker stand sold separately.
