Commentary
Horn type tweeter announced under Exclusive brand, also used in model3401 speaker system.
The diaphragm uses a beryllium diaphragm with a diameter of 35 mm and a weight reduction of 0.07g. Combined with a high magnetic flux density magnetic circuit, it realizes high frequency reproduction at 45 kHz.
The horn shape adopts a diffuse type with wide directivity to improve the localization characteristics.
A rare earth cobalt magnet is used for the magnetic circuit, achieving a magnetic flux density of 20,000 Gauss.
In addition, the voice coil is made of pure aluminum edgewise wire with alumite coating to increase the conductor occupancy rate in the magnetic gap and improve the efficiency.
