The 3.2cm ring radiator type tweeter is carried in the high region. Power handling capability is heightened by pouring in magnetic liquid between pole piece and a yoke. Moreover, since magnetic liquid leads a voice coil to the central axis of pole piece automatically, its accuracy of a unit improves and it is enabling little distorted play. Tone control of a two-step change is carried in high regions. The traditional acoustic suspension system is adopted as the enclosure, and the low-pitched sound play is improved in air inside the enclosure by which full sealing was carried out acting as a spring supporting a corn.
