Queenway Aurum Cantus G3ST-D aluminum super high-pitched speaker loudspeaker

super high-pitched speaker/loudspeaker HIFI speaker.

​

The Aurum Cantus aluminum tweeter is the same as the dome, cone and other speakers. The difference is

that the latter’s diaphragm and 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 tweeters such as the

dome, the cone and the like have not yet 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%.

       The aluminum belt diaphragm is made of specially processed pure aluminum material. It is required to be

extremely thin and light. Due to the full-width conduction, the DC resistance is very low (low impedance). It

cannot be driven by ordinary power amplifiers. It must be designed to produce a high The quality of the

transformer, that is, the efficient connection between the diaphragm and the amplifier. After thousands of

experiments, the precision transformers for aluminum ribbon tweeters of Aurum Cantus have been developed

with high efficiency, low frequency bandwidth and small distortion, which successfully solved the difficulty of

low impedance of aluminum diaphragm.

        In order to achieve high sensitivity, the aluminum belt type speaker requires a magnetic flux density B

value of the magnetic circuit system to be strong enough. The U-shaped magnetic circuit structure developed

by Aurum Cantus has high magnetic utilization rate, and the expensive N40 NdFeB magnetic material is used.

The B value of the magnetic gap reaches 5500-6000 Gauss. This makes it easy to obtain high sensitivity. The

sound pressure level in the direction of the G2 spindle reaches 96dB/w/m, and the sound pressure level in the

direction of the G3 spindle reaches 100dB/w/m, achieving efficient and high-quality electro-magnetic-force-

acoustic exchange.

          As a high-frequency transducer and radiator of the frequency-divided speaker box, the gold-plated

aluminum tweeter has comprehensive and excellent physical and technical characteristics. It is connected

with wide frequency response, high sensitivity and small distortion. Not only does it respond well to simple

harmonic signals, it shows high-fidelity waveform reduction capability, and it also has a variety of music

signals, especially percussion, plucking (and testing square waves, squeaking, etc.). The response is very

fast, the wavefront follows well, and the attenuation has no delay. This can be said to be an important

expression of "high resolution", and related to the richness, activeness, delicateness, softness, and directivity

in the horizontal plane in front of the radiation main axis. Good (that is, the tolerance is wide and symmetrical)

and so on. These hard-won achievements are expected by music, audio professional and enthusiasts, as well

as the sincere dedication of the people who care for consumers.
