Commentary
A compact speaker system with 3 types of variations to suit your room.
The metal screen fits in the Saran of the primary colors of red, blue and green, and the aluminum angle tightens the design.
Two 10-cm cone type woofers are installed in the lower range.
A large magnetic circuit of 36 φ x30mm is adopted, and it is a Skyper edge type to withstand large amplitude.
The H-50, a horn type tweeter using a duralumin diaphragm of 20 μ thickness, is mounted in the high range.
A metal baffle is used for the front baffle in order to increase the effective volume and make low-frequency reproduction more advantageous, and in order to prevent unpleasant resonance even at high sound pressure.
The enclosure is constructed by a tight combination of laminated acoustic plywood.
The network section is equipped with a high-speed automatic recording device manufactured by Brueel Co., Denmark, which measures electrical characteristics and determines the results through listening tests.
