Heat-Resistant Aluminum Voice Coil Bobbin. Most common subwoofer failure factor is Voice Coil Burnout. By using heat-resistant aluminum voice-coil bobbin with higher thermal conductivity, heat is easily transferred to the iron parts. This will Increase durability of the voice coil. |
|
Newly-Designed Airflow Control The air is pushed by the cap, the voice-coil is cooled when air passes through the gap. |
|
Closed Yoke Design The closed yoke realizes larger magnetic circuit to increase heat radiation, the more metal the better the heat radiation. |
|
Computer-Optimized Spider Redesigned shape to equalize the stress to increase mechanical durability. |
