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.
Passive subwoofer speaker with attractive parameters and built-in low-pass filter for powerful deep bass. The heat dissipation hole design ensures safe and effective work, the low frequency is flexible and natural and powerful, which is very suitable for home theater.
From design to material selection to proofing, every step is carefully designed by our engineers and technicians. Every step of the way is hands-on, presenting a work of art for the client.
