Commentary

Semi-hard type dome type tweeter.

After carefully selected fibers are woven and molded for the diaphragm, two layers of brake agent are coated to obtain a brake effect that cannot be achieved by machining.

CCAW has been adopted for the voice coil to reduce weight, and the mass balance with the diaphragm is kept optimum, the high range limit is expanded, and transient characteristics and resolution are improved.

Different types of sound absorbing materials are filled inside the magnetic circuit and the vibration section to eliminate internal standing waves and unwanted resonance, and to minimize resonance at fo to reduce distortion factor.

Ferrite magnet is used for the magnetic circuit.

By using square rigid duralumin panel, resonance is prevented. In addition, special treatment is applied after hairline treatment to bring out the beauty of the material.
