Queenway Aurum Cantus G2 aluminum band tweeter Rectangular
aluminum band tweeter tweeter pair

The Aurum Cantus aluminum tweeter is the same as the dome, cone and other speakers. The difference is that the latter’s diaphrag mand voice coil are two parts. When combined with the magnet, the charged voice coil cutting magnetic line is generated. Drive the power and move the diaphragm (piston movement). Due to this working principle and the limitations of the structure, the amplitude frequency characteristics and phase frequency characteristics are more distorted, the frequency response is difficult to obtain a wide enough, and the sensitivity is also suppressed. Although the Aurum Cantus aluminum belt speaker also needs a magnet, the key is to ingeniously combine the voice coil and the diaphragm. The charged diaphragm is fully actuated in the magnetic gap, the diaphragm is flat and light, and the force has no phase difference. High conversion efficiency, wide frequency response, low distortion, good diaphragm control and good transient characteristics. It is the ideal tweeter.
The thickness of the diaphragm of the gold-plated aluminum tweeter is only 0.01mm and the width is 8.5mm. It is hand-crafted into a hexagonal honeycomb shape and then folded into a special wave shape, which achieves a good overall rigidity and is difficult to form a severe vibration. The requirement is that the amplitude-frequency characteristic is superior, the phase-frequency characteristic interference is avoided (that is, there is no influence of phase difference), and the "pure" vibration state that the tweeter such as the dome, the cone, and the like has not been reached or is difficult to achieve has been obtained. The frequency response range is broad and flat, and the G2 frequency response range is 1700Hz-40KHz±3dB. G3 frequency response range: 1300Hz-40KHz ±3dB, the upper limit of the effective frequency response range of the actual G2, G3 aluminum ribbon tweeter has a large margin, the upper limit of both models can reach 100KHz, the second and third harmonic of G2 The wave distortion is below 1%, and the second and third harmonic distortion of G3 is below 0.5%.
