3-Layer Fibre Woven Radial Rubber Surround

The surround is required to precisely control the huge power handling and extended linear excursion.
This design eliminates surround puckering at large excursion, resulting in louder, more controlled bass response with improved durability.
The honeycomb pattern reinforcing cloth evenly distributes strength throughout the surround material, eliminating any weak points of surround and improving high power capability.

    * Improved power handling capabilities
    * Reduced distortion caused by the surround changing shape under extreme power conditions
    * Improved linear excursion - Louder more accurate bass
