The speaker system of the 50th anniversary of a Diatone studio.

There was a color variation (it is an option except the Forest green of a standard color) of all the 7 colors in a net grill.

Both high and low-pass diaphragms are unified with a corn type, and it is considered as all corn 2 way excellent in the acoustic image normal position.
It does not color by adopting as a Woofer the Woofer direct connection currently used by the monitor system, but an original sound as it is is reproduced.
