In D-80 which overly adopted the large-sized unit (80cm), it is a Woofer system for Hi-Fi systems.

The honeycomb construction corn of Diatone tradition is adopted as a unit.
In order to heighten the ability of this diaphragm further, the aramid fiber which unites and has a high specific modulus and a moderate internal loss in skin material was adopted, and it has completed as an aramid honeycomb diaphragm.
Furthermore, the high resolution pile low-pitched sound play with a quick transient response is enabled by adopting a high-heat-resistance voice coil and a powerful magnetic circuit.

In order to also make the output of audio amplifier fully drive, it is the high efficiency design of 100 dB/m.

A baffle plate is begun and composure is given by considering the whole enclosure as grain finishing.
