Commentary

This 3-way speaker system uses Delta Olefin Refined Corn.

Based on Delta Olefin, which has completely eliminated the peculiarity of sound peculiar to the diaphragm material of Woofer and Scoker, Delta Olefin Refined, which has increased rigidity by 4 times of Young's modulus by controlling the added compound, is adopted.
We have also succeeded in increasing the power of the magnetic circuit by using a voice coil bobbin made of polyimide resin.

The tweeter uses a soft dome type made of chemical fiber with uniform thickness. The diffuser is designed by computer analysis and exhibits excellent directional characteristics.

We have wood-grain D-3R and black finish D-3R (B).
