Paper / Kevlar cone is used for this unit.

The diaphragm is an FST unit with a Kevlar cone. The FST maximizes the effect of Kevlar by improving the response time of the cone and sound transmission integrity, and the frame is designed to minimize the impedance to airflow from the rear of the driver.

A 2.5 cm metal dome type tweeter is installed in the high range.

The enclosure has a curved cabinet structure and uses a closed system.
