For QY-303 white series, we use a unique white paper cone with a special formula. The sound of the paper cone is smooth and natural, bright and clear. Because there are countless fibers intertwined with each other, the energy transferred in it can be quickly absorbed to form a good damping. Therefore, the basin split resonance caused by the high end of the vocal frequency domain is not obvious, and the roll-off cut-off band is also It's smooth. This can be said to be a very good feature. In terms of human voice alone, the paper cone is very good, nothing else.

Imported German rubber edging, thickened rubber edging to ensure the back and forth movement of the bounce, which cannot be copied and replaced, and is also a guarantee of sound quality. For a full-range speaker of this diameter, the low frequency is good. In order to extend the high-frequency response of the speaker and increase the high-frequency SPL, speaker manufacturers often use the process of putting a copper short-circuit ring on the magnetic core (Faraday copper ring for short), so that eddy currents are generated in the copper ring that are opposite to the current that increases in frequency. The impedance is reduced and the input current of the voice coil is increased, so that the high-frequency output of the loudspeaker is increased, and the frequency response is broadened. This design also reduces the harmonic distortion component, thereby reducing the distortion. The drum paper is made of virgin pulp, and the resolution is very good. The dynamic details of the silk and bamboo percussions in pure music can be heard, and they are well connected and layered.

The advantages of the full frequency band: the full frequency band is sounded with a unique sound source, from low to high overall continuity and good natural fidelity, and the sound is fresh, pure and hearty. It has high efficiency, beautiful sound, no need to use different units and crossovers, no loss and phase distortion, good transparency, good range balance, high-frequency details sufficient but not harsh, low-frequency restoration is loose enough and not Vague, sweet and warm tone, natural and true mid-frequency performance are its big advantages.

Especially when listening to the recording of a single instrument or a single vocal, its effect is almost spooky.
