CORAL DX-SEVEN/II

Commentary

This 3-way speaker system was developed with the theme of realizing highly pure music space.

A 31 cm cone type woofer is installed in the low range.
The diaphragm of this unit uses a two layer carbon graphite cone incorporating a new material.

A 9 cm hard dome type skoker using new material is mounted in the middle area.

A 3.6 cm hard-domed tweeter is installed in the high range.

Level controls for mid and high frequencies are provided on the side of the enclosure.

The enclosure is sealed and the front baffle has a round shape to suppress the diffraction phenomenon of sound waves.
