GOTO UNIT SG-38W 160,000yen(one-set, around the 1979 time)

The cone type Woofer for professional of 38cm aperture.

The flat cone is adopted as a diaphragm, the lightest-weight cone material is pressed in this class, and the hardening by special penetration material is given. Moreover, aluminum is used for a voice coil, and consideration is added to the diameter of a coil so that a tone-quality fall may be prevented at the time of a large swing. Moreover, it has prevented separating from a magnetic field by putting how to consider it as a careful numeration also on coil width or an edge damper.
