X-Motif Cone with Diamond Array Pattern
The newly designed X-Motif [A] Cone not only adds strength to the cone but also controls resonance frequency and cuts unnecessary frequency, delivering powerful and solid bass response. The Diamond Array Pattern [B] enhances sound and reduces distortion.
Airflow Control & optimized heat dissipation
The Close Yoke Design [A] has a strong magnetic circuit with the purpose of reproducing deep low frequencies and optimized heat dissipation.
The combination of the Heat-resistant Alminum Bobbin [B] that provides higher thermal conductivity and the Newly-designed Airflow Control [C] that cools the voice coil when air passes through, ensure the efficiency and longevity of the subwoofer.
Computer-optimised spider
The Computer-Optimized Spider has a redesigned shape to equalize the stress to achieve very high levels of linear travel and increase mechanical durability.
Close Yoke Design
Realises a larger magnetic circuit provides higher thermal conductivity.
