The X-motif cap, made of Injection-Molded Polipropylene, controls resonance frequency and cut away unnecessary high frequency sound to deliver powerfull, solid bass. Diamond shapes are etched all the way to the speaker edge, helping to reduce surface waves on the speaker diaphragm, decrease vibration, and suppress distortion. The diamond array pattern also provides additional rigidity to the speaker to improve voice coil response for dynamic and clean audio reproduction.

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.

The air is pushed by the cap, the voice-coil is cooled when air passes through the gap.

The closed yoke realizes larger magnetic circuit to increase heat radiation, the more metal the better the heat radiation.

Redesigned shape to equalize the stress to increase mechanical durability.
