Commentary

This is a speaker system for the 50th anniversary of Diatone Kobo, which was born from the idea of sound interior with excellent music reproduction ability and beautiful finish.

The vibration plate of each speaker unit is an all-cone 2-way with a cone shape, and excellent sound image localization is obtained.

A 13 cm cone type woofer is installed in the low range.
This unit is designed to suppress peaks in the high-frequency range and attenuate naturally. It realizes a direct connection method that connects directly to the unit without using a network, thereby suppressing deterioration of sound quality in network circuits.
In addition, even though it has a small diameter, it has a large magnetic circuit to improve low-frequency drive performance.

A 3 cm cone type tweeter is installed in the high range.

The enclosure features a bass-reflex design and exterior with a Birds-eye-Maple gloss finish.

Uses a gold-plated speaker terminal that also supports banana plugs.

The net grill has a total of 7 color variations.
Forest Green is included as standard, and other 6 colors are sold separately as an option.
