Commentary

A bookshelf-type speaker system designed based on the design criteria adopted by large systems.

A 18 cm cone type woofer is installed in the low range.
A pulp fiber cone is used for the diaphragm, and a 40 mm diameter titanium bobbin, copper plated aluminum voice coil is used for the voice coil.
The frame uses a cast frame.

A hard dome type tweeter with a titanium diaphragm is mounted in the high range.
By installing a large rear chamber at the back of the unit, the influence of the back pressure of the woofer is eliminated.

The enclosure is interwoven with 1 - and 2-inch thick materials to increase strength and reduce sound coloring.

There were 8 variations in the finish of the exterior.

There was a special floor stand as an optional item sold separately.
This stand is filled with sand.
