Commentary
This is a bookshelf type speaker system that uses a soft dome unit and is the top model of the 30 series.
A 25 cm cone type woofer is installed in the low range.
This unit was developed in collaboration with Brown and speaker developer Dr. Kurt Mueller, and provides extended bass playback.
Rubber is used for the edge of the unit.
The mid-range is equipped with a 5 cm soft dome type squaker, and the high-range is equipped with a 1.9 cm soft dome type tweeter.
The diaphragm of these units is made of Terylene, a polyester synthetic fiber, and liquid rubber is smoothly attached to the surface of the diaphragm. This diaphragm is manufactured by hand by skilled craftsmen one by one to eliminate the distortion of sound quality caused by the diaphragm.
In addition, these units are designed independently to avoid the effects of low-frequency enclosure vibration and to prevent mid-range sound from becoming muddy or falling.
The enclosure is hermetically sealed.
There are two variations of the appearance, walnut and white finish.
It is removable with silver aluminum plating metal with anodized aluminum on the front.
There was a connection cord with DIN standard connector LK9C sold separately.
Other than that, there was a special speaker stand.
