The paper cone adopts Taiwan’s high-end new technology special formula foamed edge pitted paper cone, which has a high elastic modulus and a good combination of rigidity and flexibility. Compared with ordinary paper cones, the degree of compression of the fibers is relatively low, and the overall cone is relatively thick. , The natural frequency is relatively low, can withstand a large vibration stroke, increase the low frequency dive and the compliance of the speaker, the special formula of the cone material, make the sound more solid and durable.
