Commentary

A two way floor type speaker system using a large diameter woofer and a low distortion horn.

A 38 cm cone type woofer is installed in the low range.
The cone used is made by Horley Inc. in the United States and has excellent internal loss and stiffness.
The magnet uses a cast inner magnet type, and the voice coil uses a 105 mm diameter large-diameter short-stroke voice coil with improved efficiency by edgewise winding.
The frame part is made of aluminum die-cast to suppress parasitic vibration.

A horn type tweeter is installed in the high range.
The diaphragm is made of titanium, the voice coil is edgewise wound with aluminum ribbon wire to improve efficiency and input resistance, and the magnet is cast inner magnet type to reduce distortion.
The horn section is a short-cut type made of die-cast aluminum. The multi-pass equalizer and large acoustic lens are used to match the phase characteristics to achieve excellent directivity.

A ferrite core containing coil and a special metallized film in the network section.
It is also equipped with a continuously variable level control for high frequencies.

The enclosure is designed with a bass reflex using a high-density conifer particle board, with side plates 20 mm thick and baffles 28 mm thick, with sufficient internal reinforcement.
The exterior is finished with a Motoki veneer of elm.
