Features ESP Subwoofer


  • Carbon Fiber Blend Cone (CFB) - The CFB composition uses a powerful carbon fiber-based cocktail to  To offer you the highest strength-to-weight ratio in the industry.
  • Vario-Density Extended Range of Motion Surround (V-ROM) - Provides the ultimate in linear control at high excursion while allowing for dynamic sounding bass reproduction. The control ribs are compressed to a lower density than the main surround body to allow for a stepless control system. The harder you control it, the more control you get.
  • Tuned Spider System (TSS) - Each suspension is tuned to specific performance characteristics, e.g. High Definition, Power Handling, X-Stiff Control.
  • Super-Frame (SFrame) - Maximizes spider diameter, cone diameter, suspension deflection and thus works as a secondary shorting ring and provides additional heat dissipation for better heat flow from the coil.
  • SuperCharge option possible!
