Commentary
Two way speaker system.
B-199A which is 30 cm cone type woofer is mounted in the low range.
A cone made of pulp and paper and wool is used for the diaphragm, and a variable density system is used. The density is highest in the central part and decreases as it goes to the periphery. This prevents interference due to flapping and reflection of propagating waves and provides a constant response.
Two 5 cm cone tweeters, B-200Y, are installed in the high range.
The cone is placed on a foam rubber platform to damp spurious peaks and vibrations. Similarly, ranges above 10 kHz are handled by a 2 cm aluminum center dome. This is based on the principle that the diameter of the cone must not exceed the wavelength of the maximum reproduction frequency.
The enclosure is hermetically sealed.
The exterior is designed to remind you of the Greco-Roman art, with grill cloth and iron decorations all over the panel and a oak finish.
