The ESP subs are products of over 30 years of subwoofer innovation. Everything we’ve learned along our journey has directed the evolution of our subwoofers; hence why we call it the Evolution Subwoofer Package. ESP allows us to address several performance issues plaguing standard subwoofer designs.
True Size Carbon Fiber Blend Cone (CFB): Allows for more cone area and bass output from a given box size while staying in designated size classes. The CFB composition employs a potent carbon fiber based cocktail to give you the highest strength to weight ratio of any pulp cone in the industry.
Vario-density Extended Range Of Motion Surround (V-ROM): Provides the ultimate in linear control at high excursion while still allowing for dynamic sounding bass reproduction. The control ribs allow for a continuously variable control system through expansion and contraction.
Super Frame (SFrame): Maximizes spider diameter, cone diameter, suspension travel, works as a secondary shorting ring and provides additional heat sinking for directing heat away from the coil.
