DIATONE D-80E

Commentary

A large woofer system developed for the theater hall.

D-80E and D-80S are used for different purposes and have different characteristics.

80 cm cone type large diameter woofer unit is used for the unit.
This unit was developed by making full use of the honeycomb technology cultivated in space technology, and the amplitude at the time of heavy low-sound high-output reproduction is very small, enabling reproduction with less distortion.
Honeycomb construction cone is used for the diaphragm. In this cone, coarse fiber with high specific elastic modulus and moderate internal loss is used for the skin material, and coarse honeycomb diaphragm is used. In addition, high resolution, heavy and low sound reproduction with excellent transient characteristics is possible by driving with high heat-resistant voice coil and strong magnetic circuit.

Weight reduction has been achieved by adopting a honeycomb diaphragm with a large diameter but mostly composed of air layers.

The enclosure uses a bass reflex system.
