Full paper cone (speaker paper for the British senior full-range speaker paper, light as a feather, thin as silk, toughness comparable to aluminum-magnesium alloy)

Cone has a long history, but the sound is not outdated, high-end full-range speakers symbol. WE / Altec 755A full range Goodman Axiom 80 full range Altec A5 / A7 AR 3a Lowther TAD and so on all special for the cone, but the non-general cone comparable to the process of paper pots, especially this artificial paper Pots are more non-ordinary baskets comparable, can not be confused, the paper for the things that are soft and hard, and made of trumpet cone, the requirements of hardness and softness in order to adjust the distortion and basin distortion and so the minimum so the German sound of the British sound And so have their own unique research and development of the secret, this is why the Chinese people can not design such a good voice, the reason lies in the secret of the pot, this basin is designed by the British designer to sound good, In addition to the cone, no choice of speakers using a special voice coil flat copper package aluminum design, high-quality sound protection

In general, the sound characteristics of the cone is smooth and natural, crisp and clear and not neurotic. Because the innumerable fibers are intertwined, the energy delivered in them can be quickly absorbed and formed to be well damped, so that the basin split resonance caused by the high end of the acoustic frequency domain is not obvious and the cut- Very smooth. This can be said to be a very good feature. Alone to the human voice, the cone is the best, no other. The other material of the basin to listen to the human voice is a bit weird and not kind enough.

The rigidity of the cone is quite good, and it has a good performance for the details of the instantaneous reaction and the hearing. Do not look at the common paper is soft, in the appropriate shape and thickness, the paper is able to do a very good rigidity. Moreover, if the design and production properly, the cone can be done very light, than the lightest plastic diaphragm is also lighter than 15%, but in fact the difference is not, so the sound high efficiency.

Other materials made of the speaker, and some hear the first feeling is very good, but the actual listening down two or three hours always feel a little tired, and the design of the cone is more easy to get a pleasant ear cone, a long time to listen to music is not tired. To be resistant to hearing, only the pots.

The characteristics of the cone

The possible weakness of the cone is that its properties change with the humidity of the environment, and the sound will become affected by the fact that the density of the paper becomes high (variable weight) and the rigidity becomes worse (softening). As for this change is good or bad is hard to say, it was declared in the rainy day, the home speaker particularly nice. It seems justified.
