PS-series 30cm subwoofer

The KFC-PS3017W PS-Series 30cm Subwoofer delivers deep, solid bass with up to 2000 W peak power from a rugged polypropylene cone and high-ridged two-piece diaphragm. A heat-resistant aluminium bobbin, stress-controlled spider and advanced airflow control support reliable, high-output performance, while its 4 ohm design and sealed or ported box compatibility make system building simple.

  • Oversized Dimension
  • Heat dissipation technology

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.

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.

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.

Close Yoke Design

Realises a larger magnetic circuit provides higher thermal conductivity.
